No, no plans for making a mold Maxie. One of the guys is using poly fixing up a Jones Brothers and the stink is killing all of us!

No, we feel the honeycomb's properties of excellent compressive strength, resistance to skin peeling and sound deadening are best suited to decks and that's it. The difficulties of edge finishing keep us from using it for much else.

A very good friend who builds VERY high tech custom sportfishing yachts in Florida tried it on bulkheads with not so good results. We've shared ideas and techniques for decades and he was kind enough to give us a heads up before we went down that path and made the same mistake (knowing we would've tried it!). His son is following in his footsteps and building a bad ass 37 that happens to have a thread on the first page! One of the benefits of being on friendly terms with the majority of other custom builders, we all try and help each other!

Those were my thoughts too. But I know a few (maybe 1 or 2) manufacturers who use Nidacore as a core for structural applications (stringers and transoms). Just wanted to hear your opinion on the matter.

I can see an argument for transoms but I'd want to core out and crush sleeve motor mounting bolts at least. I've seen hardtops done well with it too, just have to edge band the perimeter for a roundover. I'm used to taller stringers but either way, using it on end or thicker cells, you'd still have an exposed edge or two that you'd have to somehow fill before rounding over and glassing. Seems like a lot of additional work!

You're just smelling the sweet fumes of progress mixed with styrene Bills. You get used to it after a few weeks!

Step outside kln, the fumes are getting to you again!
Geez, you'd think a high tech operation like that would at least provide good respirators.

Or did it blow off on that test run the other night?

Did KLN cross over to the dark side of the force and start spraying polyester resin for a living?

Oh, it's worse than that Maxie, he went to the "cat" side

I though you knew, he's now under the tutelage of that gentleman up in Little Washington who's pushing the envelope all the time. Cat's Egrets, anything carbon. Hopefully grasshopper is learning infusion, not chopper guns!

I was hoping he would hop here.
Grasshopper is always learning.
He just looks around.

1. It doesn't smell as bad when its under vaccum in a bag.

2. If 1 hull is good, 2 must be better.

3. You should have put a step in it!

Oh no, it's worse than I thought, poor kln really has gone over to the dark side. Maybe there's still hope! He could be just repeating the mantras so he can blend in.

I think he's in good hands with Master Yoda, a.k.a.Otseg....as long as he completes his training.

I'm having as much fun as you can possibly have without being brought up on charges! Carbon is a fickle lover.

This thread has been haunting my thoughts a lot recently. I have a couple of questions about the whole build.


You scarfed the outer half of the hull back about 18" and laid in overlapping layers of glass, which then wrapped around the transom, correct?

If you couldn't flip the boat - say it was a customer boat that you didn't want to strip out - do you think the strength of the hull would be compromised by scarfing the inside instead? There's a local manufacturer that takes this approach and I've wondered since reading this thread if there's a structural advantage to working from the outside, or if it's just an easier way to work, provided the hull can be flipped.


The other thing I've been wondering is this: given the huge amount of work you're already doing, why bolt on a bracket? Why not extend the stringers through the hull and make one? Any particular reason?

Yes, we scarfed foreward 18" and overlapped new glass around and onto the transom. We also did pretty much the same on the inside. It would be very difficult to splice in with sufficient strength on only one side of a single skin laminate, you'd have a huge fairing issue at best. Much easier (but dustier!) To grind back and taper it in.

just not a fan of the eurotrasom look. We already extended the running surface and was impressed with the Hermco brackets and decided to order one for her.
