Default What makes a "fast hull"

so I have recently changed to a smaller boat due to lack of time to use, docking, family, reastoring an old house etc..I have a 1994 221 liberator with a 502 (375 at the prop) I picked it up last August to have something to trailer for occasional use. The boat is very clean and should work perfect for my needs. Everything I read tells me this is a 60-62 MPH boat. I have scene over 60 on GPS in it in the couple times I have used it with me the wife, the kid and full of fuel gear etc.. note this is running an old raker prop that looks like it is probably original and not exactly pristine

so i'm trying to figure out why this should only be a low 60 boat with 420HP, 21 deadrise, 4000lbs I know it is a fairly heavy hull for its size but I see others with 25'-27' boats with stock 502s claiming to run 70 and they are heavier or atleast as heavy

so what is it in the hull design that makes it fast? I am not talking stepped hulls either, I understand that

I do plan on buying a new prop and having it labbed once I get some accurate numbers early in the season

The x dimension is probably to low and it has a hook for safety reasons. Or there just isn't enough bout to have a high x and keep the motor under the hatch.

One other thing a good driver can be worth 3-10 mph.

BB, don't worry the "driver mod" is not going to be needed in this case

The drive is deep but the hull has no hook at all unlike the older Liberators

A black jump suit and a few gold chains can make a big difference.....

c-mon we all know Reggie needs a little help with his personal style,

but on a serious note is there that much difference in th hull itself or more that these manufacturers spend the time on set up to get every MPH out og thier hulls

I would think that weight distribution would play a role in speed, so different props change your attitude in the water depending on what your after. My 02
