Flattie DRAG BOAT Top Speeds...

[2manymustangs]

It's an APBA legal K boat bottom. I'm sure it's blueprinted to the hilt.

My understanding is there are things that make the boat more stable in a straight line but hurts the ability to turn and vice versa. Chines and tunnels and strakes are examples. Reducing the wetted surface area also makes the boat faster (in theory). So the further back on the hull or plates the boat rides the faster it could be. But, too nose high is unstable and not high enough is too wet to be fast enough. And that just covers bottom basics. You still have a whole other topic of balance, HP, Torque, prop diameter, prop pitch, prop cup, and aero/fluid dynamics which all affect the handling and drive-ability of the boat.

BTW, I stood back and quietly watched Dave meticulously adjust/check the plates mid way through the Long Beach event, for about 30-45 minutes... That was pretty amazing to see what he ended up with... (it might have been with Robbie on the SS1)

It was NOT AT ALL what I expected but it certainly made me say Hhhmmmmmm (thinking of the plates being an extension of the bottom...)


As for the bottom (blueprinted to the hilt), I agree totally. I'll wager the bottom of that hull (K69) has had more study than any one flat bottom out there knowing the last 6-7yr history and knowing Rank Daddy&Gordy...
