Hull Blueprinting
I've been playing with the idea of doing some work on the hull of my boat for about four years now. Looking at the recent article in Family and Performance Boating, got me thinking again. Years back, I noticed a hook in the bottom, and was wondering if taking it out would help performance. According to the magazine's article, they removed a 1/8" hook, and picked up 4 mph. I have a similar hull, and I think my hook is more pronounced than that. Any thoughts on this? I'm thinking about doing this near the end of next season. If it's worth it.
I don't know if this is something I want to do myself though. Anyone know a good glass guy on Long Island?

a blueprint on hull to get the hook out will cost more if you want a final finish of gelcoat instead of bottom paint, most of the time they charge by the foot. i'm not sure what the going rate is, but it sounds like an easy speed increase without going into the motor

My boat is bottom painted, so I don't need a high gloss finish. According to the article in Family and Performance Boating magazine, the place up in Maine that did their 24' Scarab would have charged $550.00 for the work they did. That included a glossy gelcoat finish. I wonder if that would be a good ball park figure to go by. I'm in NY, nothing is cheap here!

My 32' Active Thunder had a hook in the hull. I had a shop remove the hook from about the last 3-4 feet back to the transom. He sharpened the strakes and the edge where the tansom and bottom meet. Using my GPS, at 4000rpm I went from 64.5mph to 69.5mph. I haven't been able to conduct a fair top-end comparison yet. I would guess that it would be about the same gains...4-5mph.
Marty Bowker did my hull. He's located in Holland, MI. Holland is right on the shoreline of Lake Michigan. He can be reached at: Bowker Fiberglass (616) 218-1683

I just now paid the bill for my hull repairs and blue printing the bottom. Lots of work on chine repairs to the "old Sonic".
Total cost was 1000.00 for the repairs and blue printing with a total new gelcoat bottom for a 31 foot boat. Hope that helps....

I had mine done a few years ago. Unfortunately, the net gain was zero. you have to consider how good the bottom is to start with. Mine it appears was very good. Cost was less than 1k. They only work on the wetted surface when the boat is on plane. So even on a long boat, it is only a certain percentage of the hull bottom. There have been other cases where people have picked up 4-5 MPH.

Does anyone know of someone we can trust in the NY/CT area to do this work?
An old repair has shown up on the hull(paint peeled) since the boat has been out of the water, and I'd like to regelcoat the entire bottom.
