If you care to run the math, this will get you close:
Minimum Planing Speed in Knots:
2.3 x ((32.2 x (all up displacement in pounds)^0.333)^0.5)/1.6889
For example, an 18' boat at 2,323.2 pounds (including crew) may plane at 13.902 knots.
The formula has no input for the shape of the hull. It just calculates the speed required to lift 2300 pounds. It also does not indicate how difficult it will be to get the hull to 13.9 knots. However, in my ignorance, I believe it may be somewhat representative. If the boat was surfing down a wave at 13.9 knots, it may very well be planing. |
i can tell you right now that this boat wont fully plane out till close to 30 mph but why don't we leave this investigation to the investigators? my thoughts and prayers are with the people involved
