Delphia 46 DS – tested and reviewed

Delphia yachts’ new 46 ds, a polish-built cruiser that’s taking on the bluewater market.

The premise behind the yacht is simple enough: to produce a big, comfortable boat tailor-made for a couple to go bluewater sailing. That puts her right at the top of the Delphia range and kitted out with all the bells and whistles you would expect to come with a flagship – generators, watermakers, washing machines, sauna… all right not the sauna but I’m sure you could get that as an extra if you paid enough.

Inspecting the yacht from the quayside, her lines are easy on the eye. The hull was designed by Andrzej Skrzat back in 2008 so the hull is actually somewhat retro. Funnily enough though, what goes around comes around and design thinking in many ways has moved back towards the 2008 school. She has a modest, easily-driven hull with no chines and somehow that seems rather contemporary. The only thing that betrays her vintage is the lack of a plumb bow and her sugar scoop transom.

Step aboard and the centre cockpit is a nice place to be; it’s very secure and sociable. The fact that you are able to put the mainsheet aft of the cockpit where it is both within reach of the helmsman and out of harm’s way is a massive bonus on a serious cruising yacht. There is also a lot of storage on deck, with good-sized lazarette lockers and further storage up forward just abaft the anchor locker.

There were also plenty of indications that this is a yacht intended for serious bluewater sailing, with the huge arch over the transom that carried both the tender and a radar and gave the yacht an air of purpose. Meanwhile the hydraulic bathing platform with its clever drop-down step was a clever, luxurious touch.

Room with a view

Stepping down below doesn’t involve much stepping down at all thanks to the deck saloon, and the dominant feature is the masses of light that streams in through the huge wraparound window. To starboard is a big dining area with two bench seats running athwartships and also a nifty little flip-out seat at the end. The table can also drop down to create a third double berth, although this might be rather a noisy spot to sleep. There is good access and ample room for a generator beneath this seating area.

It makes for a very sociable area, as everyone is at the same height and the cockpit also feels highly accessible, so the helmsman does not feel isolated if everyone else is below.

I tested the Delphia from the boatbuilder’s base in Gdansk on the Baltic. The day was crisp and clear with a very modest 10kt breeze. The beautiful scenery promised to demonstrate the capabilities of her deck saloon to perfection, but I was rather concerned that the light breeze might defeat this heavyweight cruiser with her rather modest sail plan. Happily I was wrong and she behaved very well.

Sam’s verdict

This is a yacht that fits very snugly into the category of bluewater cruiser and Delphia has clearly worked hard to ensure she ticked all the boxes.

She was very comfortable, supremely easy to handle, thoughtfully laid out and finished to a high quality. She sailed surprisingly well in light conditions and the hull looks sea-kindly enough to handle the rough stuff.

She may lack the cachet of, say, a Swedish bluewater cruiser, but she is good value for money by comparison and Delphia is a proven performer these days. Her trump card is that swing keel option which will mean that, for some, she is the only option.

Quick Look: Delphia 33

• By Jeremy McGeary
• Updated: September 12, 2007

Still a newcomer to the North American market, Delphia maintains its determined assault on the status quo, introducing its third model in as many years and its smallest model to date.

Curvaceous deck lines and thoroughly modern window styling atop the slick hull belie the traditionally inspired, teak-centric decor below. A huge berth under the cockpit takes advantage of the hull’s generous beam aft and fullness forward allows the V-berth to fit well up in the bow. With the head tucked aft, to port, this allows room amidships for a comfy saloon and workable galley and nav desk, all finished in smart joinerwork with little gelcoat in sight.

The sail plan and keel appear nicely balanced and the swept-back spreaders should assure minimal interference between the shrouds and the 110-percent genoa. www.delphiayachtsusa.com

Delphia 24 Review

Andi Robertson took  the Delphia 24 for a spin.

The Sportsboat market has had its peaks and troughs. The SB3 is very much the boat of the moment and fleets continue to grow both nationally and internationally. The 1720 and Hunter 707 markets have bottomed out, but new fleets are growing organically as well-priced boats are snapped up in different areas around the country.

The Delphia 24 Sport was launched in Poland to meet a perceived demand for an inclusive package one-design Sportsboat and since then it has sold comparatively well with fleets growing in Germany and Poland. Since it was launched last year the 24 has sold 33 boats outside of Poland and more recently there have been three boats delivered to Sydney, Australia and a further three to Sweden.

Things have not been so brisk in the UK, where the market is doubtless tighter and more complex. On the Forth at Port Edgar, Delphia’s dealer in the north — Jock Blair of The Bosun’s Locker — has been campaigning his Delphia Racer most of the season, while the one boat on the south coast competed in the Round the Island race finishing 15th in a class of 70.

Both boats competed in the Sportsboat class at the Scottish Series in May and took fourth and fifth. They were both beaten by three 1720s, but in turn came out on top of the remaining Melges 24, Beneteau 25 and J/80 collection. But the lack of sales success so far is in part down to lack of exposure. The boat needs to be actively raced in the main series along the south and east coast of England to achieve any kind of sales.

Design and build

Delphia Yachts are no pocket outfit in Poland. They have more than 20 years experience building yachts and powerboats in Olecko. Indeed, with an output of close to 3,500 units each year they are increasingly becoming a significant player. In the late 1990s they were contracted to build for Jeanneau and Feeling, and more recently they have also built runs of J/92s and J/80s, giving them experience of building series production performance boats.

It was some two years ago that they saw a market opening for a fast, open monohull which would be good for slightly more advanced sail training and handicap and one-design racing. The 24’s first racing season in Poland was a success as a strict one-design fleet, boosted significantly by the creation of the Delphia 24 Cup, which was sponsored by Toyota and drew an initial entry of 20 boats. There is a very active class association in Poland.

The Delphia 24 was drawn by renowned Polish designer Andrzej Skrzat. He is the architect chosen for the full seven-boat Delphia range from the 24 up to a 40-footer. He has also done the Majestic 24-footer, which is a similar concept but with a little open plan interior.

Conceptually the Delphia 24 does create its own niche. Unlike the 1720 it is a ‘sit out and hike’ boat, which — having sailed the 1720 more than enough — I rather like. Unlike the Melges or Beneteau/Platu 25 it is a face-in rather than out boat. It has more freeboard than the Hunter 707 and is easily trailerable on its lifting keel.

The hull shape and form attracts inquisitive glances. It has very distinctive chines and concave, hollowed topsides aft, giving the appearance of a stretched slightly retro National 12. Forward the entry is both powerful, and relatively shallow and slender, but there is certainly ample buoyancy forward. The lines are very dinghy-like with flat topsides forward, working aft to this hallmark concave sheer.

Designer Skrzat explains his thinking, ‘The ideas of the hard chine aft and the concave sides are several, but mainly when the boat is heeling the longitudinal hull side shape helps reduce leeway and complements the work of the centerboard (ballast) blade on which the side force is reduced, allowing it to use more of its ballast as righting moment. The concave hull sides also increase the hull sides’ strength and stiffness, prevent splashing with water and when the yacht is fully planing it doesn’t make stern waves but only diagonal bow waves what reduces drag.’

Rig and layout

The coachroof blister is pronounced and almost disproportionately high, but it does a job allowing ample headroom in the little working area ‘downstairs’. There is loads of working space in the cockpit and the big, open transom keeps the boat dry.

The deck layout is pretty conventional. The gennaker is launched from a shallow lateral kite bag set at the forward end of the cockpit floor. The alloy sprit is centre mounted through an aperture in the stem. There are stainless foot rails/grab bars on the bow which we never used in anger, instead sailing all the time with the genoa up.

The mainsheet is set on an alloy hoop with a central swivel jammer. The backstay is led forward to give control to the helm, while all the remaining controls are mounted on the aft edge of the coachroof, or — like the tackline and the pole outhaul which run through the ‘cabin’ — are conveniently mounted to hand on the starboard side, while to port is the jib cunningham and forestay tensioning tackle. The kicker is a conventional cascade system, which has a long tail allowing it to be tensioned or released from anywhere in the boat, and I rather liked the neat detailing on the clever washboard which drops in tidily and securely.

The alloy rig offers plenty of tuning options. Spreader angles are secured by what look like slightly heavyweight bottlescrews, but along with the jib cunningham, forestay tension and shroud tensioning there is plenty to get right — and wrong — to make the boat go quick. The main has a distinctive rounded roach area, while the genoa has a slight overlap and is sheeted to short tracks on a conventional 2:1 system. Sheet loads on both sails are on the light side, making it ideal for lightweight crews. The keel is a cast iron straight vertical daggerplate weighing 275kgs, which gives a draught of 1.62m keel down, or 23cms with the daggerplate and lifting rudder raised.

On the water

We enjoyed a mixed fleet handicap race at Port Edgar. Under Sportsboat rating the Delphia 24 races off 0.908, which makes it slightly quicker than the J/80 and slower than the Melges 24. Some quick maths says the Melges will give the D24 three minutes in the hour, and it will in turn give a J/80 about 1.5 minutes. Sailing four up — three crew 85-90kg oldies aged 40-plus and one 54kg female former 420 and 470 sailor — we had a great evening race.

In many respects this, at the design’s formative stages in the UK, is its preferred domain, delivering heaps of simple fun on a handicap racecourse. It was quick enough to stay with the 35ft cruiserracers upwind in 14-19 knots of breeze with us enjoying the burn of a little hiking and leaving the J/80 behind. I daresay that a well-sailed J/80 up against an average crew in a D24 would be more of a match but we were going well upwind.

The boat handles like a dinghy upwind, but with the added security of a lump of ballast to stiffen it slightly. Certainly in terms of weight on the helm and responsiveness it was like a dinghy, but pleasingly positive and direct. If anything I felt a little more rudder depth/area might help in the stronger stuff when the boat was well heeled, but we rarely had a problem. Upwind in the gusts the boat remained pleasingly balanced while feathering with plenty of lift staying attached to foils.

It is not an especially stiff boat, and will certainly relish crew weight on the rail. Four-up is fine, but five lighter weight individuals will not cramp the cockpit nor leave anyone excessively redundant.All the while upwind there was no particular feeling of being overpowered in terms of the sheet loads. Again, with dinghy-style rachets on the jib leads and the mainsheet purchase there was no problem in de-powering the main or the jib slightly and re-sheeting them, even for the lighter crews.

My biggest disappointment with the boat is the standard sails package. They are acceptable as a ‘get going and get racing’ inventory but Delphia UK are offering a package with Sobstad which will add a further £2.5k to the all up price. That would be money well spent. The gennaker shape is simply odd, with a very high clew and rounded luff profile, and lacks drive and area on the leech. One direct consequence was that for the wind strength and sail area we were setting, the boat sometimes lacked power in marginal conditions.

When it hit the plane, it reached flat and true and handled well. On a tight spinnaker reach was where we felt the kite was not making the most of the boat’s potential and there appeared too much sideways and upwards drive rather than useable twist and a nice tight luff.

Downwind the D24 proved quick and easily handled. We especially liked the cockpit space, which makes manoeuvres easy to accomplish, affording time and space to see what is happening. We pulled a couple of basic broaches coming out of the gybe too hot and too quick, but this is a boat which should find favour with tuition establishments looking for a simple, well performing boat to teach asymmetric techniques as well as the basics of performance keelboat sailing.

Delphia 24 Review: Verdict

Overall we came to rather like the Delphia 24 Sport. It is a thoroughly entertaining mix which does offer some very different performance characteristics than the current crop of the UK and Ireland’s popular Sportsboats. It is less physically demanding and easier to sail well than the Melges but more fun, with a lighter, more dinghy-like feel than the plodding 1720. It is drier and feels more of a big boat than the Hunter 707, yet retains the tune-ability and demands of a performance dinghy.

But in the end you have to come back to weighing up the USPs versus the cost. It is a well built, nicely finished boat which, if it had Laser or J-Boats or RS branding, rather than the slightly dated and insipid East European styling on it, would likely be selling in slightly greater numbers. The bottom line is: does it offer enough of a different sailing experience to warrant a new allup price of £20k? Or are you better to compromise and buy a good used Hunter 707 or a 1720 and know you simply can’t lose on the deal?

The answer is that the boat is good enough to warrant the price and as a new boat it is good value. The D24 will appeal to those who want something a little different, but it may be some time before we see fleets building in the UK.

Delphia 40.3

Built in Poland, the Delphia 40.3 is a classic cruising sloop that can be configured in many ways to suit each buyer’s needs  (published January 2016)

We motored down Back Creek and out into Annapolis Harbor and the Bay. Once clear of the channel we put the throttle down and were happy to see that the 40.3 will make close to eight knots at maximum revs and will cruise at a comfortable 6.5 knots at cruising revs of 2200 rpms.  At cruising speed and in flat water, the engine will burn approximately half a gallon per hour, which translates into a safe cruising range, with 55 gallons of fuel in the tanks, of over 600 miles. That’s comforting to know.

The wind was hovering around five to seven knots, not really enough to give the boat a serious sea trial. But, in the light breeze, we were able to get her going and get a sense of her balance and speed potential.

The boat we sailed had the twin-wheel option and the shoal  draft keel option.  Hard on the wind you could sit to leeward in the cockpit to get a good view of the telltales on the genoa and trailing edge of the main. Hard on the wind, the 40.3 will sail at about 28 degrees to the apparent wind and has an easy groove when the main is trimmed right. With the smaller genoa, the boat tacks easily and held her speed well through the tacks despite the wind being fairly light.

The 40.3 was designed by Andrzej Skrzat and has a pleasing and traditional look. With a long waterline, easy sections below the water and efficient foils, the boat feels fast and nimble. The design’s non-dimensional ratios tell a lot about her design profile. Her length to beam ratio is a modest 2.8, so she is relatively narrow and therefore more easily driven than boats with more massive beams.

After an hour of sailing we motored back to the marina and slipped her into her docks without any fuss or bother. Both undersail and power, the 40.3 handles very well and is fun, fast and surefooted.

The simplest layout and one that will appeal to couples who often cruise alone and occasionally invite friends and family aboard will be the two cabin layout with two heads and the galley aft. This provides for a good seagoing galley and plenty of storage in the large port cockpit locker.

But you can opt for a layout with two cabins aft and two heads. This three cabin layout will work for families with children or couples who like to sail with multiple friends aboard.  The three cabin layout has the galley running fore and aft on the starboard side.

BWS THOUGHTS The Delphia 40.3 has been in production for several years and has proven to be a boat that fits the needs of many different sailors with different sailing styles. Circumnavigators have chosen the 40.3 for their adventures because the boat is solidly built and is such a capable long distance passagemaker. And coastal sailors who only sail a few miles each weekend have found the boat fits their needs very well, too.

Delphia 11 review: The future of inland boating? Diesel & electric head to head test

• Electric boats
• Top stories

With Delphia committed to building only electric boats by 2024 its Delphia 11 Sedan is its first step towards a greener future. Jack Haines heads to the Netherlands for a back-to-back test with its diesel counterpart...

Looks really can be deceiving. It may not appear so from the outside but the Delphia 11 could be the most important boat launched in 2022, not because of what it is but because of what it stands for.

Candela, Vita and X Shore are all building cutting-edge electric boats for the top end of the market but the Delphia 11 is a commitment from the biggest boat builder in the world to mass produce electric boats.

The Polish brand, which was bought by Beneteau Group in 2018 will be electric only by 2024. Not only that but alongside their partner, Torqeedo, Delphia and Beneteau Group have committed to investing in the electric boats charging infrastructure in certain markets to boost confidence in its electric-only product.

The 11 is Delphia’s first foray into all-electric boating and to put it through its paces in a realistic environment, we were invited to the Netherlands to test the electric Delphia 11 Sedan alongside its diesel sibling and a diesel-powered flybridge version of the Delphia 11, dubbed the Flylounge.

Delphias of old were renowned for their bang-for-buck approach, with oodles of living space for a reasonable asking price and, although they were equipped to go offshore, most found homes on the rivers and lakes of mainland Europe.

Delphia bluescape 1200 fly review: inland favourite gets coastal cruising upgrade.

£353165

The modern Delphia product is entirely focussed on inland boating and was designed by Tony Castro from the keel up with electric propulsion in mind. The hull is a full displacement hard chine design with an upright stem and full bow sections in a bid to balance generous interior volume with stable, efficient, slow- speed cruising.

Even with the 150hp diesel version of the Delphia 11 you’re topping out at 8.5 knots so life in the slow lane really is the name of the game. From Delphia’s base in Makkum we would do a loop of the local waterways with a stint on the IJsselmeer, swapping between the three boats for an ideal back-to-back taste of the differences between cruising aboard identical diesel and electric boats.

Delphia 29 is a 28 ′ 1 ″ / 8.6 m monohull sailboat designed by Andrzej Skrzat and built by Delphia Yachts starting in 2004.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Fixed keel version draft: 6.75’/2.05m. (High performance verson) Up later upgraded version is the DELPHIA 9.2.

Anyone know much about this company? I'm taking a look at a 2007 Delphia 37. I've just sold a 1984 C&C 35-3 and the plan is to take a sabbatical from racing and get a nice performance cruiser to cruise around on Lake Michigan. For the age, length and overall appearance of the boat on the listing it seems like a great deal. Almost too good. Much less than Jeanneau and Beneteau. Sail and all other publications with a review of the boat seemed to think it was comparable to those other production builders and it appears popular in Europe. I guess my fear is that the boat is the European equivalent of a Hunter and that is why it's cheap (not a jab at Hunters btw, I just believe they are usually considered in different company than Catalina, Jeaneau and Ben). On the surface it looks the boat we want. I don't want another 30+ year old boat as they have too many of their own problems, I don't seem to like much from the 90s and anything post 2010 is way too expensive. Anyone owned or sailed a Delphia? Maybe on a bareboat in the Med?  

Delphia build their boats in Poland where wages are lower than in Germany and France. I found a Danish test of the boat, it says that the build quality is good. There are lots of Polish yards that have been subcontracted by the known European brands to build hulls.. I would guess that the price reflects that the brand is unknown in US.

We would sometimes like to sail a larger boat, but since the market has degenerated into 95% weak/cheap condo's and 5% daysailer/racers..... shopping is tough. And frustrating.
