Pontoon boat hull speed calculator. Max Speed Length-at-Water-Line LWL x 5 x 134 For yours. Boat 37 mph is not unreasonable. Two hulls allow the boat to be more stable and sit on top of the waves while a mono-hull vessel sits in the waves.

It happened back in 1978 when a speedboat used a jet engine instead of a propellor to power the boat. MaximumPower kW 3 X Lh X Lh X Dp. Empty Hull Weight Engine lbs.

The last 200 rpms were slow in coming however. If youre running a 150 Yamaha on a 3000 lb. 24 x 5 x 134 16 mph This suggests that a little more motor would get you to 16 mph.

4551 The recommended maximum power in kilowatts marked on a capacity label for an outboard powered pontoon vessel is determined in relation to the length of the pontoons squared and the diameter of the pontoons as follows. As a very general rule the maximum speed of any displacement hull--commonly called its hull speed--is governed by a simple formula. Mercury Marine uses the following formula to estimate potential top end this calculator uses this formula.

V is the speed at which the boat is traveling. Average runabouts cruisers High speed runabouts very high speed cruisers Race type boats. For most pontoon boat captains the real goal is to hit the golden 22 mph 36 kph mark.

For Displacement Hulls. Because typical pontoon boats use displacement hulls and have no planning capability the design speed can be approximated by multiplying the overall length of one pontoon by 15. What the classic hull-speed formula assumes is that 134 is the maximum SL ratio that can ever be achieved due to the characteristics of waves we discussed before and thus always serves to limit a boats top speed.
