Web30 aug. 2024 · Here’s a table of hull speeds for monohulls, which is a useful reference when comparing speed. Hull speed isn’t the absolute fastest that a boat can go, but it’s … WebFor a sailboat with a waterline length of 20 feet (6 m), the hull speed is 6 knots. For a large cruising sailboat with a waterline of 40 feet (12 m), it’s about 8 knots. And for a 300-foot-long naval vessel, it’s 23 knots. In practice, it’s very difficult to make a displacement boat go faster than about 1.5 times its hull speed.

If the hulls are asymmetric above waterline this is a sum of outer hull halves. B H1 must be bigger than B WL of the hull. We’ll put here in our example: B H = B H1 + B CB B H = 7.07: Now we can calculate the beam of our catamaran B H (Figure 4): Z WD = 0.06 × L WL Z WD = 0.72 decathlon cycles for adults
