What is Capsize Screening Formula (CSF)?

The capsize screening value for Montgomery 15 is 2.72, indicating that this boat would not be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 4.9 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

One Hundred Choices for the Best Small Cruiser

* = Seven boats appear in above lists twice.

Listed on the opposite page are one hundred choices for the "Best Small Cruiser." There are, of course, many more than one hundred choices for the "best" small cruising sailboat. In fact, there are 360 choices reported in this guide alone, and at least a few boats beyond those, on which we failed to find sufficient data to include here. In any case, as the saying goes, one man's meat is another man's poison. That is, a sailboat that one person does not like at all can be one that someone else likes very much.

One of the main reasons for this is that different boats are designed for different purposes: boats best for cruising in shallow bay waters versus deep ocean waters, for example. Styles vary to suit different tastes: traditional versus modern design, for example. Boats that do well in around-the-buoy racing may not be so well suited to cruising. A boat built to the highest standards of quality may not suit the pocketbook of the casual weekend trailer-sailor. And the range of choices goes on and on.

To help narrow the field of choices for the reader who is eager to find the right boat to buy, and doesn't have the patience to wade through all the facts and figures on all 360 boats presented in this guide, we have (somewhat arbitrarily)

devised a hundred choices, broken into groups of a dozen or so. Are you looking for a single-masted character boat? We list thirteen of them here, from 18 to 25 feet on deck. Do you yen for a two-masted yawl or ketch? We list every one of the dozen covered in this guide. Do you prefer a custom- built boat or at least very high quality construction? We show thirteen "high-end" choices, though you could find others in these pages. We also list fifteen good cruising boats for a family of four, and another thirteen for a cruising couple without children or guests aboard. We choose fifteen round-the-buoys racers for your consideration, and a dozen blue water cruisers, including a 15-footer that has sailed from California to Hawaii (though some may not agree that such a feat qualifies such a boat for offshore work).

Although there isn't space to include photos of every boat in this book, or even the one-hundred choices listed as "best," we have dug up representative sample photos from our vast collection of boat sales brochures to include on the following pages. They are arranged in roughly alphabetical order. If you don't find a picture of the boat you're interested in, try searching Google. There's a huge cache of photos there.

Attach the jib sheet to the clew of the jib and run it through the pulley at the base of the mast. Attach the main and jib traveler lines to the tracks on the deck and thread them through the blocks at the mast base. Attach the mainsail to the mast and boom and the jib to the fore stay. Attach the main tack to the clew and then attach the clew to the boom. Attach the jib tack and clew to the forestay.

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)
