Monohull sailboat speed. Old cruising catamarans may not go faster than 8 knots and modern monohulls can exceed 10 knots. Cruising speeds of over 8 knots are uncommon. Classic hull speed formula.
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. Race Route Distance NM Date Yacht Type LOA ft. Top speed unofficially is 3245 knots aboard the 140 Mari-Cha IV sustained for short bursts.
Monohull boats tend to sail downwind and in choppy seas better than catamarans. Most sailboats cruise at a speed of 4-6 knots 45-7 mph with a top speed of 7 knots 8 mph or 13 kmh. Transatlantic W to E Ambrose Light Lizard Point.
Otherwise the vessel had two or more persons. 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. If the approximate theoretical hull speed of a monohull displacement sailboat can be calculated.
Previously the highest speed ever reported was from the crew of lHydroptère. 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. Again some large high performance monohulls have hit over 30.
In 90-120º true she should do 20-26 knots when we will be tearing sail area off. 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. Drag specified would get you.
