P class question
What are the different P classes?
Size, Power, Speed? Thanks!...Mark |
P-5 70 mph
P-4 80 P-3 90 P-2 100 P-1 110 There is no rules as to size power just speed. |
I don't think there are any restrictions as to size, power or drive choice. The classes are broken down by speed.
|
There is also a Px class for the all out boats.
|
Does anyone know the equation they use to equate the speed of your boat??
|
does the P class have to be V only or can it be a Cat???
Maybe i should race :) NOT!! ;) |
can be Cat or Vee...Speed is the only factor....:cool:
|
Allen, try this, it's very accurate. Basically, prop pitch x gear reduction x RPM x slip factor x hull drag.

do they radar you for top speed???
how do you depict what class?? say my boat does 80 can top oout higher on a perfect day but 80 is the normal or do they use what someone said about a theory calculation? |
