Re: SB18, CB position vs bulb keel position

The CLR of a CB will have more lead than on a fixed keel. The lead is the difference between the sail CE and the keel (CB) center. Plus, I consider that the builders who choose a bulb keel are performance oriented and will often use the spi therefore, that sail CE will, most of the time, be more for...

Re: Question for Jacques or Richard Woods

The Skoota has probably more displacement but, for your program, I would pick the Skoota and not even consider the PC24. Each boat is designed for a program. The structure of each boat is very different. To try to adapt the PC24 would produce a poor result. The PC24 is an excellent open pontoon boat...

Re: Central FL OB15

Yes and No. You start with one layer of tape and later you will add the overlaps of the wide fabric. This gives you 3 layers outside. With the inside layers, this creates a strong and stiff beam. The scantlings are in the new notes that I rewrote last month. The previous scantlings were identical bu...

Re: Jeffs FS14 LS

Scale everything by the same factor in CAD. It's easy and safe.
No need to increase the hull skin thickness but OK to go up one notch with the stringers.

Re: Would a 8-10 gal baitwell be OK?

Not larger than that please. Think of the surface effect. 8 gallons is large for that size boat. Make very large radius corners for better circulation.

Re: C19 in Richmond, VA

2 gallons of EazyFillet should be enough.
Do not use too much putty. A 1/2" radius is fine. The fillet's job is to allow the fiberglass to take a nice turn around the corners. 1/2" is more than enough for biaxial 12 oz. and 3/8 is sufficient for small corners like furniture done with woven glass.

Re: TW28 build in steel?

I missed your location: Oman.
Epoxy-plywood is not as difficult as steel but I understand your choice now.

Re: Jeffs FS14 LS

1. Motorwell: it depends. If you install the motor on a bracket, you don't need a motorwell. For a motor bolted to the transom, you need the splashwell in order to tilt the motor and to provide room for the steering IF you have remote steering. If you have a motorwell, drill a drain hole through the...

Re: FS 17 with tunnel?

Like all the other ones, there are pros and cons to all tunnels but the small boats like the FS17 are more affected by the negative effects. I would not do it.

Re: Year 8 !!

Boat does look great! And more important is that the owner/builder is still pleased with it 8 years later. Amen. That and the new boat launching post are my preferred ones. Currently, I am following (on Facebook) the new paint job on a C19 built 20 years ago by Jim Wright. He sanded all the paint d...
