Previously the highest speed ever reported was from the crew of lHydroptère.

Monohull sailboat speed. HS Root LWL x 134 What would be the equivilent formula for a Catamaran. The consistent speed promised by this boat could break new ground for a monohull. Transatlantic W to E Ambrose Light Lizard Point.

This gives them a speed advantage during ocean voyages. In 90-120º true she should do 20-26 knots when we will be tearing sail area off. Hull Speed 134 x LWL A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the SpeedLength ratio constant of 134 with a calculation based on the DisplacementLength ratio.

Expect sailing speeds in the 6-plus knot range in 10-15 knots of true breeze. Drag specified would get you. Murnikov is certain that with the right crew and weather conditions his boat will cross the Atlantic in record time reaching top speeds in excess of 50 knots.

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. With winds around 20 knots the 1600 will glide along at 9-plus knots. Larger racing yachts can easily reach speeds up to 15 knots 17 mph or 28 kmh with an average cruising speed between 6-8 knots 7-9 mph.

Again some large high performance monohulls have hit over 30. Since no monohull is hitting speeds of 40 knots or more the World Sailing Speed Record Council has no records of top speeds other than during monohulls record attempts at 24 hours or longer. Usually accepted that the greater the boat speed the greater the cost to buy and operate and the smaller the payload- it will be shown that the same value of high speed can be designed into all monohull hull shapes not necessarily just small vessels without compromising their hydrodynamic efficiency provided that their dimensions are appropriately selected.

Deciding between a catamaran and a monohull is a big decision and one worth considering well before taking the plunge. Race Route Distance NM Date Yacht Type LOA ft. For easy shorthanded sailing a couple would find the perfect combination in the self-tacker and an optional screecher.
