Hook in botton of hull?
 

After reading all the posts in the Scarab section, I have read that my ScarabIII has a lot of "hook " designed in bottom. how do you determin how much?(use long straight edge from transom along the bottom?)is it worth removing(for top speed& fuel economy)Any one know anybody who does this kindof work ,(hull blueprinting)in Ohio around Cleveland?

Don't be fooled into believing hook should be removed. It may result in higher speeds but you may also lose some handling characteristics. Nothing worse than paying someone to make your boat worse ?! If the hook is real bad I'm sure some could be removed. I'd definitely do some research on hook removal. Make sure you take you boat to a competent establishment. Don't use the neighborhood autobody technician.

I've also read that just sharpening the transom/hull edge can be beneficial ?

Good Luck

from what i have hear dteh hook in the III is there to give her a ride more like a family express cruiser. Wellcraft did that in the hope that making it ride like a big ole cadillac would make it more appealing as a "family" boat instead of a just a speed freak boat. As for removing it???? I dunno if you shodul or shoiuldn;t you might pick up some speed but it will ride differently.

Coincidentally the "family" aspect of the boat makes me kind of like it more. The cabin has soem decent space in it. and it has a real head instead of those funky as porti pottis.

We took most of the hook out of my Baja and it seemed to help. Might take more out later. Dave Warden

Thanks Puder, I knew you would reply I remember how you had a ScarabIII that the guy stiffed ya on and that you always liked that model. LeeS seem well informed on all Scarabs and I was reading his posts about my "redheaded stepchild"...LOL :D ;) :eek:

I pulled about 3/16" of the 1/4" hook that was in my Concord out. I should note that the hook was only present in the outer most area of the bottom near the hard chine. I saw no real improvement in speed or the amount of required trim. I now believe that the boat wasn't running on that portion of the hull.

Thats what you get for fishing from a go fast boat. You probably have line wrapped around the prop and that will slow you down also. What happens if you are swimming under the boat an get caught on the hook? I would get it out now or bait it and try to catch a fish on the fly. :D

:D

DonziMitch, THERES ALWAYS ONE!!!!!!! :D :rolleyes: :mad: ;) :eek:

If I were you, I would call the factory and see what they have to say. You can take a straight edge up to say 10' long and lay it on the bottom from the transom forward. Slide it from the center out to the edge of the boat and see if you find any hook. If you take a point 10' forward of the transom on the keel, then draw lines back to each corner of the transom. Depending on the length of your boat, this will be the running surface at some certain speed. Wheather it be cruise or top end.. The bottom should be straight and symetrical. If it is not, then the manufacture may have designed in some hook or rocker. If you change it, it may screw up the handling of the boat.
I know of one manufacture that had two molds for a certain model. Depending on which motor you ordered, they could tell if you were a Hi performance type and used the hull with less hook.
Now I took all of the hook out of one of my boats. I did it in two steps. One year just filed down the area two inches forward of the transom.. Didnt seem to change much, cant remember if is went faster..
The next year I removed all of the hook. Well the boat ran faster, I think. But a strange thing would happen. Running along at 60mph in 3'-4' water, then comes along a little bit bigger wave and bingo.. It was like you launched the space shuttle, bow would go straight up, then trip and almost stuff. It would set the nose in and the stern would walk on the prop.. Boat stops in a few feet. Well I finally did some calling around and found out that I needed some hook back in the bottom. But I didnt put it back on the pad area, I move out a ways and addes some hook back in. Then I could run 70/75mph in 3'-5' water.
So if you want to modify your hull, check out someone else's research first. Find someone that has done it on the exact same hull as yours, same year, etc..... to make sure it will do what you want it to..

I hope this helps .....good luck..

We blueprint every bottom of every boat and will tell you we certainly think it is worth it. We don't like to give out our research, but it made a huge difference adn there certainly is a right and a wrong way to do it. If you are going to get it done, drop me a call and I will give you a few pointers. If done corectly, your boat can handle better also.

I had the bottom flattened out on an old 30 Scarab I used to have, and noticed no difference. If you realy want some info, try to hook up with Glassdave. He doss realy good work, and he's out of Toledo. Good luck.

TTT :D ;) :rolleyes: :cool:
