I wanna build a mini race boat...

[Suprathepeg]

First off, I think that at 230 pounds you are dreaming if you want something under 9 foot. You simply need more boat to float you. Second, while I didn't see the hull mentioned, these boats are very desirable. I did have my tunnel hull on craigslist for 1200 complete with engine and trailer. Most people did not want the engine and offered 1000 so I decided to keep the rig myself.

Fair enough, so what would a good size be for my fat ass?

I would say something with a lot of beam at the transom. so it displaces a lot of water at rest. Those little 3 point hydros are very narrow at the stern and a lot of weight will put them dangerously close to the water. I mean this: My 10 foot tunnel is just shy of 4 feet at the stern. I weigh just about 160. When I step back to drop the engine after launching. The water level washes the deck. So, you would want something at least 5 feet maybe 5 1/2 at the transom and probably a length of about 11 feet.. Mind you this is just a guesstimate. HOWEVER If you join Screamandfly forum these guys will probably tell you exactly what you need to know.

And at 6'2' you probably don't have a fat A** we'll say it is all muscle. LOL

I am 6'3" and weigh 240, and the Doc thinks I am just about right for my build, age and injuries I have sustained over the years, you you are definitely not a fat ***. That said, guys of our size do need something more to support us, then those smaller guys in order to be safe, something in the 11 - 12' range is probably going to be much safer for you, to light and you run the risk of swamping or flipping at speed. I spent a of time watching and photographing Unlimited Hydros when I was 15 and 16 as I worked part time for a company named the Squire Shop, so I spent a lot of time with Chip Hanauer(Miss Squire), Bill Muncey(Miss Atlas Van Lines, d.1981) and Dean Chenoweth(Miss Budwiswer, d.1982) They knew a heck of a lot about racing boats. I was lucky, I was still able to have the career I wanted and got to meet some great boat racers before I went in the service and at the time I interacted with these guys, I was a sponge and I believe you are trying to put yourself in to small a boat.

I'm 6'4" 250 lbs and could stand to lose 30-50 lbs and I jokingly call myself a fatazz while trying to remember to keep my gut sucked in lol...

I once (~20 yrs ago) purchased a 17' champ boat hull but at the time I was unable to do anything with it and eventually lost storage space for it and it died a fiery death.... :-(

Would have loved to put it on the water.

Anyone see one of these around?

Is it a hard one to build?

The Class CD wont be that difficult to build, its basically just frames set on a level beam on a jig or horses....then ribbing and ply.

Heres some shots of the skeleton.

The plan will come with templates for the frames and other specific parts.

For something fun I might seriously suggest taking a look at the "cocktail class racer". It is intended for simple home construction an completely stock outboards. Maybe not good for your size and build, but I would check it out.

Been doing some digging and I think the best power train option is a jet drive from a jet ski. They're light and much more available than the older high power to weight ratio outboards. The problem is can I fit one in an OK-9?
