Re: Reefie's LB26

Very nice and done as it should be with the glass overlapping the edges.

Hi Narfi,

I was wondering if you plan on putting biax tape over the floor to side joints.
Yes I will tape and then glass both.

Yes, do it. It is a must, that seam is structural.

Re: Cleaning up sloppy fillets.

T, are talking about fairing the seams for prettification? If so... I’m out. I’m the “ugly but floating is good” type. Pretty is the wife’s job. And she’s a pro at it. That's the way I build my boats. I use your brushing technique but that's all: run the fillet in one big move. Don’t touch it again...

Re: SK14 using a 9.9hp outboard motor

5, 7,8, 10 HP, the boat can take it, the transom can take it but it may become tricky to handle at excessive speed. There is somewhere on youtube a video of the SK14 running fast with a 10 HP (there is a link on the forum). Just be careful, it is possible to get in troubles going too fast. There is ...

Re: Foam sam'ich epoxy.

Correct, 50% of the finished weight. Thanks for the clarification. Many production boats are built with only 30 to 35% glass in cheap polyester resin. In production boats, I used to take a hull sample (tru-hull), weigh it, burn it in a lab oven and weigh it again to see how much glass was left. A re...

Re: Foam sam'ich epoxy.

Very good description Fallguy.
The redesign of many plans for foam sandwich will be for open mold (hand layup) and I expect a careful laminator to get 50% resin content. All those boats can also be built with infusion, no difference in hull shape or specs.

Re: Foam sam'ich epoxy.

I tested foam panels with SilverTip and it is what I base my foam sandwich specs on. I know that Jeff sold a more performant epoxy resin from System Three to several builders, by the drum. I will talk to him unless he replies here. In the meantime, for all our small boats in foam use Silver Tip. I h...

Re: OD16 Barrelback transom, will this work?

Yes. The width and number of slits depend on the curvature. I would start with 3 and add some in between as needed.

Re: GF16 seat slope question?

In those small boats, the trim will vary very much underway. At rest, it depends on the size of the engine, tank and batteries but in most cases, the boat will trim down by the stern a little bit. You could drill some small drains in the corners. I have a GF16 and did not bother: afloat, the boat wi...

Re: C23

Yes, the CS23 requires more material than the C21 but if we scale the C21 to 23', it will get close. It's not just the hull planking but the amount of glass and resin. A larger boat will require a thicker bottom, more framing etc. Plus, the CS23 is designed for more top speed in heavier conditions, ...
