Some of these comments seem rediculous and biased against fountain.
For starters power requirements are not linear but rather exponential. That is it takes a lot more horsepower for small gains in speed. This becomes a mechanical challenge. It gets harder to ring more hp out of an engine. Look at the cost and longevity of say a 500 hp and a 1500 hp engines. You only have to look at the cost and rebuild schedules to understand how different they are.
As far as the hull is concerned. There is not much that you can do to modify the hulls It will come down to some fine tuning. Current v hulls are very efficient. There is not going to be much of the boat in the water. The real work will be on balance and aerodynamics. Water is very hard at those speeds. The boat has to run straight, a hook at those speeds will cause a loss of control.
It will be a major accomplishment if they are able to break 200 mph.

I’m not pulling for anyone or anything here. Just stated that it would be cool to take HP out of the equation. I could care less who has the silly title.

Thanks for showing us the progress as you build, and good luck and be safe on the run. Given the recent accidents I can't say I think this is the right time to try this, but that's really not any of my business to decide either. Be safe dudes!

I’m confused. So they were just supposed to pop it out of the mold bottom untouched and run it? Rigging should be typical production rigging even though it’s a custom manufacturer? Who was supposed to drive it? A 1350 pleasure sv43 ran 155+ at loto so those weren’t 1650s in the race boat that set the record?

Reggie Fountain's 42 lightning hull (40 race) uses two steps and runs on a pad. The OL hull design of the SV 43 uses 5 steps but no pad. Without that pad and more steps the OL is no doubt fast but it tends to run flatter and wetter up front. The downside is that it tends to bow steer. Not good when you are racing or trying to break a kilo record. Such is the design quirk with the OL hull design that sometimes will spin out on the race course even when going in a straight line.
When OL wanted to capture the kilo record they towed their boat to North Carolina.and hired Reggie's ex-setup guru and his gang of ex-Fountain bottom guys to put a Fountain-like pad on the bottom of the OL Kilo boat, as well as to make other design modifications to the hull to make it run more like a Fountain. This is no secret and common knowledge to both the Fountain and OL camps - but apparently not to some on this site.
All's fair in love and kilo wars. OL owns the kilo record fair and square and you won't see Reggie crying online that OL had to hire his ex-protege to copy his hull bottom in order to take the record. But when people on this site start complaining that the Fountain should run the same engines as the OL to get "A true comparison of which hull design is superior" I'll bet it makes Reggie's head almost explode - as it should.

That's funny. A little history here.

.
a few big shots went to Fountain this past week also ==> https://speedonthewater.com/in-the-n...o-boat-project
if you're going for the record and do it productively and safely it's good to get industry leaders to give a helping hand.
its all good!
