What are sail dimensions?
Foresail and mainsail dimensions are universally referenced with the letters ‘J’, ‘I’, ‘E’ and ‘P’ approximating to the length of the foredeck, height of the mast, length of the boom and the height of the main sail – but more accurately defined further down this page.
How is sail area measured?
The conventional way to find sail area is to calculate the area of the foretriangle (FT) between the mast, headstay, and deck; the area of the mainsail triangle (M) between the mast and the boom; and add them: SA = FT + M (= IJ/2 + PE/2).
How big should a sail be?
The ideal sailboat size to sail around the world is between 35 and 45 feet long. This length will ensure a high enough maximum hull speed, good handling in high waves, and enough cargo capacity to carry multiple weeks of food and water. Longer boats will perform as well, but are more expensive too.

How do you calculate sail load?
A: The load on a sail is proportional to the sail area times windspeed squared. The formula is: (sail area [in ft2] x windspeed2 [in knots]) coefficient = load. In our shop we use a coefficient of 0.00431. For a 350ft2 sail in 30 knots this yields a load of 1,358lb.
Is a spinnaker a sail?
A spinnaker is a particular type of sail designed for use when a boat is reaching or sailing ‘off the wind’. For example, when on a broad reach or run. Like other sails spinnakers come in different sizes and it is not uncommon for a race boat to have two, three or even more spinnakers as part of its sail wardrobe.
How do you calculate jib size?
The best way to measure the tape is to use Calipers that can measure in millimeters. If you don’t have a set use a set of drill bits and either slide them up the track in your furling system or hold them up to the luff tape on your existing sail to determine the proper size.
How large of a sailboat can one person sail?
between 35 and 45 feet
So how big a sailboat can one person handle? Well, a sailboat measuring between 35 and 45 feet (10.5 – 14 meters) with a draft of about 2 meters, plenty of sail area, easy reefing, and well-working assistive equipment can be ideal for one person to handle.
How fast does a 420 sailboat go?
The AC72, the type of catamaran used in this year’s race, can travel almost three times the speed of the prevailing wind. On June 18th Emirates Team New Zealand recorded a speed of 50.8 mph (44.1 knots), with a wind speed of about 18 mph (15.6 knots).
How much force is on a sail?
While the force on the sail is 640 pounds, the force on the sheets and halyards will be much higher because they need to hold that force at various angles. For tensile strength, you would need a line that can withstand 1077.5 pounds as a minimum.
How much power can a sail generate?
The solar panels in the mainsail are of sufficient size to generate an average of 1,000 watts of power, and the boat has a further 1,000 watts of solar panels. This is sufficient to drive it at four knots under power during daylight hours without taking any charge from the batteries.
How big is the hull of the Rs 400?
SPECIFICATION RS 400 Designer Phil Morrison Length 4.52m (14’10”) Hull Weight 88kg (194lbs) Sailing weight (ex foredeck) 129kg (284lb)
Who is the designer of the RS400 dinghy?
[edit on Wikidata] The RS400is a light-weight sailing dinghy designed by Phil Morrisonand manufactured by RS Sailing.[1] The dinghy is sailed by two people and has a main, a jiband an asymmetric spinnaker.[2] It has a PYof 948[3]and a D-PN of 82.3.
How to calculate the ratio of sail area to displacement?
The ratio sail area to displacement is obtained by dividing the sail area by the boat’s displaced volume to the power two-thirds. The ratio sail area to displacement can be used to compare the relative sail plan of different sailboats no matter what their size.
Is the RS boat a joy to sail?
The RS boats I have sailed are all brilliantly designed – very well balanced and setup, a joy to sail. I think this is a huge driver of the RS success story over the last 10 yrs. Stunning performance is complemented by superb manners and ease of handling…once the sails are up, the meticulous attention to detail becomes apparent.
