J/125 is a 41 ′ 0 ″ / 12.5 m monohull sailboat designed by Rod Johnstone and built by J Boats between 1997 and 2003.

Drawing of J/125

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)

Top Gun: Maverick Finally Showcases The New J/125 Sailing Yacht

Top Gun: Maverick

The long-awaited trailer for Top Gun: Maverick was released this week, giving fans a first look at the long-awaited sequel to the beloved 1980s blockbuster. One of the most highly anticipated scenes in the trailer is the sailing yacht scene, which features Tom Cruise and Jennifer Connolly.

It's no surprise that the scene was filmed on a J/125 sailing yacht, as the J/Boats shipyard is known for its high-performance racing yachts. The J/125 is a popular model among racing sailors and has been featured in several major films and TV shows.

This article takes a closer look at the Top Gun: Maverick sailing yacht scene and the J/125 yacht that was used in the filming.

What made the Top Gun: Maverick sailing yacht scene so iconic?

The sailing yacht scene in Top Gun: Maverick is one of the most iconic scenes in the movie. It's a beautiful, serene moment that starkly contrasts with the rest of the film, which is full of high-octane action and adventure.

But what makes this scene so iconic? Is it the beautiful location? The amazing cinematography? The fact that it's such a change of pace from the rest of the movie?

We believe it's all of these factors and more. The sailing yacht scene in Top Gun: Maverick is an iconic scene because it's a perfect example of how to use all the elements of cinema to create a truly memorable moment.

The J/125 sailing yacht that was used in the filming of Top Gun: Maverick.

The J/125 sailing yacht is a state-of-the-art vessel that was used in the filming of the 2020 movie Top Gun: Maverick. The yacht, which businessman John Pompa owns, was featured in a key scene in the film where it is seen sailing past the Golden Gate Bridge.  

The J/125 is a high-performance sailing yacht that is designed for long-distance cruising. It is equipped with a variety of features that make it ideal for sailing in rough conditions, such as a keel-stepped mast and a carbon fiber hull. The yacht also has a large onboard water tank that allows it to go for long periods of time without having to stop for fresh water.

How the J/125 yacht helped make the scene of Top Gun: Maverik so memorable.

In the film Top Gun: Maverick, the J/125 yacht plays a pivotal role in the iconic beach scene with Tom Cruise and Jennifer Connolly. The yacht, which is owned by Connolly's character, is central to the scene in which Cruise's character meets Connolly's.

The J/125 is a popular yacht among filmmakers due to its sleek design and its ability to turn on a dime. This makes it perfect for action scenes like the one in Top Gun: Maverick.

But the J/125 isn't just a pretty face. It's also a highly functional yacht that can accommodate several guests. This makes it perfect for entertaining.

Why the J/125 yacht is the perfect choice for a sailing adventure?

The J/125 yacht is the perfect choice for those looking for an exceptional sailing experience. This amazing yacht offers superb performance, unmatched comfort, and stunning good looks. Here are just a few of the reasons why the J/125 is the ideal choice for your next sailing adventure.

The J/125's extraordinary stability index of 143 degrees, with a stability curve ratio of positive to negative areas of 12.5:1, is what creates a sense of solidity and power when sailing it. This greater stability is paired with a balanced hull-form that has the right amount of reserve buoyancy forward. This makes the J/125 capable of safer and more controllable high-speed planing offshore in large waves. Also, the average helmsperson can maintain peak performance for sustained periods of time because the hull-form provides a wider steering groove upwind.

The J/125 is manufactured to ABS offshore standards by TPI Composites using the SCRIMP resin-infusion process. The US Naval Surface Warfare Center at Carderock, MD found that the properties of laminates created by TPI's patented SCRIMP resin-infusion process are better than the low-energy pre-pregs used by many custom boat shops--they're even twice as strong as hand lay-ups.

J/125 weighs in at 2700 pounds, which is 1500-2500 pounds lighter than its competitor designs, after subtracting the weight of the keel and adding 1000 pounds for the rig, engine, and hardware. This is not only due to the J/125's narrower beam. The Hull & Deck Laminate Design of the J/125 is stronger for its weight than E-Glass/epoxy laminates using slit CoreCell foam. J/125 uses epoxy with a combination Kevlar & E-Glass for the outer skin with two layers of carbon fiber (bi-axial & unidirectional) for the inner skin. The elevated strength of these exotic materials allows for a thinner, lighter skin than the equivalent E-Glass structure.

It's no surprise that the scene was filmed on a J/125 sailing yacht, as the J/Boats shipyard is known for its high-performance racing yachts. The J/125 is a popular model among racing sailors and has been featured in several major films and TV shows. In fact, the J/125 was also used in the film The World's End, starring Simon Pegg and Nick Frost. The J/125 is the perfect boat for cruising or racing, and it's no wonder that it was chosen for the Top Gun: Maverick film.

If you're looking for a high-performance sailing yacht, the J/125 is a perfect choice. Whether you're interested in racing or cruising, the J/125 will provide you with an amazing experience.

“ The J-125 is a boat of exceptional stability and power. Her handling is explained by an extraordinary stability index of 143 degrees, with a stability curve ratio of positive to negative areas of 12.5:1. This greater stability is combined with a balanced hull-form with proper amounts of reserve buoyancy forward. This provides safer and more controllable high-speed planing offshore in large waves as well as a wider steering groove upwind for sustained peak performance by average helmsmen. No IMS rule-inspired hull form can match the high 4.72 length-to-beam ratio of this seakindly yacht, nor the reserve buoyancy designed into her bow sections. High length-to-beam ratio ensures straight tracking in rough seas and light steering loads. Sailboats with fine bows and full midship sections are more difficult to balance and more likely to spin out of control in big waves. As user-friendly as it may be, this is a sailing machine designed to be the fastest, best-built boat of its type in the world. A long-lasting, high-tech carbon - Kevlar - E-glass - epoxy laminate is the answer. TPI Composites is the world leader with its patented SCRIMP process. This yields a laminate that's been tested by the US Naval Surface Warfare Lab at double the strength of hand lay-up construction. SCRIMP overcomes long term ownership concerns about delamination and structural failure because there are no air-pockets in the hull laminate and integral keel beam grid. Secondly, the ratio of glass fiber to resin is 2:1 rather than 1:2, resulting in a strength-to-weight ratio that exceeds custom race-boat, pre-preg construction. ”
