Proto Hull
Photo of proto hull below being tested on its side.
a forward counter weight of 200kg is placed in the centre vee with that weight hanging out there in the centre vee the hull is self standing.
the vee is below the water line lower than the centre of gravity that has a reaction to stand up.
next to no stern drag as you can see with the shape of the hull.
18 year old engine for testing is rated from the fly wheel 250hp by the time the power gets to the propeller it is rated at 225hp as are the new engines now rated from the propeller.
the old engine on the proto hull was
braking down one carbie not working and still
0km to 60km 3 seconds with power in reserve
as you can see in the photo the shape saves massive energy leaning back on the water not needing to be lifted using the power of the engine.
side on to a wave face the hull is the opposite shape of the wave face the wave can not push on the flat surface only lift The centre vee is at a similar angle to the wave face
the wave simply goes under the hull.
imagine a 12m hull of this design and shape
with out changing the dynamics of the centre vee only the length
then only widen the flat surface by 500mm each side then you have a 12m hull
that can go from 0km to 60km in three seconds the same size engine and acceleration as the 8m but with better reach or a sail hull
have a nice Day. cheers!
