i have a few of questions about the hook in a hull. what is the hook? what is too much? how do you fix it? i've heard that it helps control bow rise and if i remove the hook i'll gain a couple mphs. appreciate any help, thanks!!

Welcome, The experts will be along shortly!

If you take a straight edge from the back of the boat and run it along the bottom about 4 feet towards the bow you will see daylight in the middle if there is a hook. If there is a gape at the back and the rest is flush with the boat there is a rocker in it. A hook will force the bow down. We had a hook in the race boat and had it flattened out. We hope to see a couple mph gain and also better handling.

there was a dude on hotboat who took the hook out of his boat and he lost hp and it rode even worse.

How would the hull effect HP?

you will need to flip the hull over.
make a rack out of 2x4 .120 or 12 gauge tube..
make it like a dolly trailer so it will pick up the stringers.
get a drywall straight edge..they are cheep. less than 20 bucks.. it is long ,use it to check the hook.
set it on edge.
if there is alot of hook and you will have to use the green stuff to fill it in...
easiest way is get a hutchins air file.
then a 2 in wide x1/4 inch thick piece of aluminum..how ever long you can find.
drill it and bolt it to the air file with the 10/32 screws.
use psa long board paper.
if you are only leveling the current gel.. 150 grit will work.
if you are filling it with green stuff... then 40 grit..
run the file slow... let the paper slowly do the cutting.. like a fat beaver nibbling on your wood.
evercoat makes some green stuff... use that . DO NOT USE BONDO OR KITTY HAIR to fill the bottom.
bondo will hydraulic off and the kitty hair is a bastard to level.
bondo is ok for very thin fillling...under 1/16 in.. remember it is for cosmetic purposes... not structural.
it doesn't flex enough. imho.some might have had good results......bondo must be coated /sealed if used... it is hydroscopic....
stay off the strakes untill you get the bottom straight..
then go back and do the strakes... or you could loose the shape.
there are ten ways to skin a cat... O0
this is how i did it.

family matters,
thanks for the info!!! i know what i'll be doing this holiday weekend. do you know how much is to much to grind off? on the trailer, from what i can reach it looks like i have about 3/16" hook.

Flipping a boat over does make it alot easier. I've been sanding and filling on my back for the last three days on a boat.... not fun :banghead:

your welcome.
lets say your long board is 3 ft long.. when you cut all the way through the gel on each end.. stop.
you don't want to cut into the bottom glass.
you will need to scuff the gloss off the rest of the gel...in the low spots...or the green stuff won't stick.
