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)

Shoal draft: 5.5’/1.69m.

Tall Rig: I:52.10’/15.88m J:14.80’/4.51m P:46.20’/14.08m E:15.00’/4.57m

With an outstanding level of equipment for a production cruiser/cruiser, the First 40 has won fame for a unique international record of achievements in IRC, as well as ORC.  A reference in the forty foot class, this boat does not compromise on safety and yet its level of comfort makes living on board very pleasant.

Interior designer :  Nauta Design

Exterior design

Highlighted with subtle decoration and a set of black stripes on a grey hull background, the bottom is as appealing to the eye as it is sailing.   The First 40 ‘Carbon Edition’ is delivered ready to race. In this format she has a carbon mast, lead keel, a black composite steering wheel, and a Raymarine electronics pack adapted to regatta racing.

Interior design

The unusual design of the interior layout of the First 40 offers maximum habitability. The shape and size of the saloon seats allow 1.95 m long berths. The wood table has two fold-down flaps and two possible positions. It can therefore seat six people in its usual setup and lowers to free space or extend the berths.

Crew sensations

Designed to lead the race, the First 40 supplements its choice of performance with solutions that provide crews with a high level of comfort.

The boat can accommodate a crew of eight, offering two symmetrical aft cabins with double berths (2.00 m by 1.50 m), a master fore cabin (1.90 x 1.40 m) with shower room and two ordinary berths can be made up in the saloon.

The First 40 users and spinnaker retractable carbon bow sprit making the use of an asymmetric spinnaker much simpler.

Both light and strong, the equipment has been chosen for its high level of performance: carbon mast, rod rigging, fibre adjustable backstay, rigid boom vang, tilting composite steering wheel.

LONDON (AP) — King Charles III and Queen Camilla will attend an Easter service at the chapel at Windsor Castle on Sunday, Buckingham Palace officials said Tuesday, in the first major appearance for the 75-year-old king since he was diagnosed with cancer in February.

Officials said Charles and Camilla will be accompanied by members of the royal family at St. George’s Chapel. The event is expected to be smaller than usual. Prince William and Kate, the Princess of Wales , who announced last week that she is also undergoing cancer treatment, are not expected to attend.

The king is undergoing treatment and has suspended almost all his public engagements since his diagnosis. Officials didn’t disclose what form of cancer Charles has but said it’s not related to his recent treatment for a benign prostate condition.

Officials have said the monarch is continuing with state business, including regular weekly meetings with Prime Minister Rishi Sunak, and won’t be handing over his constitutional role as head of state.

On Tuesday, Charles was shown meeting community and faith leaders from across the U.K. at Buckingham Palace to hear about their work of boosting social cohesion amid heightened international tensions.
