Getting back into boat plans/kits

[shine]

While its not directly related to seacrafts, I thought I would share a little on a new project. The boat is a new design, but has a lot of well proven attributes. 24 degree deadrise, 8'6" beam, integrated bracket, single or twin outboards.

This particular design is something I wanted for myself, but we designed it from the start to be something an amateur could build.

Construction method is sheathed strip composite.

SC fans will see some similarities in the sheer line

Looks nice! Any information on specs- weight, speed, effiniceciency, cost to build?

Also, any plans to introduce a VDH design?

You can see she is just a little bigger than the SC23, which is what I wanted. Still not too big to require twins, but can handle them if thats what the builder wanted.

LOA ............ 25'-5" 7.747 m
Lwl ............ 21'-9 5/8" 6.646 m
Lbp ............ 19'-4" 5.892 m
Max Breadth ..... 8'-6 1/4" 2.596 m
Depth at Lbp/2 .. 4'-4 1/2" 1.308 m
Draft at mLDC ... 1'-5 3/8" 0.441 m
Fuel capacity ….. 125 gal 470 l
Light Ship …………….. 3364 lb 1526 kg
Full Load Desp.- mLDC …. 5624 lb 2551 kg
Buoyancy reserve ……….. 1,38 m3 1414 kg

I will have a Bill of materials when the plans are complete

Also, any plans to introduce a VDH design?

Its certainly a possibility, this boat could be redesigned with a VDR running surface. I went with a more classic running surface for this one.

With 300 hp she should hit 40 knots - AT A FULL LOAD, 5200 lbs. A typical load of 1,000+ lbs less and I expect 55+ mph. 35 mph cruise is what Im looking for.

You must be excited.

Cool. Did you give the bottom the rocker and "hook" of the F233?

No hook of any significance, no need for it. A hook can help with low speed planing and maybe (no proven research I can find) with other handling characteristics. The faster you go the benefit of the hook causes more trouble than its worth IMHO

The boat will have nice big trim tabs to do that work, and trim tabs are retractable

Of course, its really easy to build in a slight hook, you just don't fair very far the overlaps of glass coming from the transom to the bottom. The boat I build will probably have around 3/16" hook, but it will be faired out to 3' or more forward


I put up the study plans last night for the CCSF25.5....
