Re: Steel vs Fiberglass

I am going to the boatyard tomorrow.
I'll bring you back some reality. Not much talk but photos of a real boat building project. Maybe the deck plug is underway. That would be exciting.
I've had...

Re: Steel vs Fiberglass

BS: You have no clue what you are talking about. Stability is way beyond your meager intellectual grasp. As usual it's just more BS from BS. Why do we bother?

Re: Steel vs Fiberglass

This is the 32' LOA version of the 43;' carbon cutter for a midwest client I have been working with for many years. With fat head main and backstay wand this should be an interesting combo of old and...

Optimistic sure but at least reasonable and coming from you, reliable. If I were to guess, and I';m actually pretty darn good at guessing these numbers, I'd say 126 deg pos stab. Maybe as low...

Re: Steel vs Fiberglass

Thanks TAD. Good for you. I have far too much respect for your work to think you endorsed those curves but I was under the mistaken idea that you tired to replicate some of the BS shapes in 3D. My...

Re: Steel vs Fiberglass

Right on Smack.
I think many of my consultation clients are surprised when I start recommending boats that are not my designs. There are a lot of great boats out there.

Re: Steel vs Fiberglass

320: Yep, I have to agree. It may be a tissue paper over a comb kazoo but by the dictionary definition it's still "music". Just very crude music that I find annoying.

Re: Steel vs Fiberglass

Here are some shots I took at the yard this morning.

The hull lam at this point is one layer shy of being complete. The there will be 8 layers wrapped around the stem. Jim figures you could pick...

Re: Steel vs Fiberglass

I spent three hours at the yard with Steve and Craig the two guys doing the 3D work for the CNC cutting of the interior components. They ask me questions. Sometimes I don;t have an answer and I say,...

Re: Steel vs Fiberglass

I'll go along with everything Robert says. Surprise! He seems reasonable to me. But I'm not sure I ever doubted his points. But there is far more to this thread than that. Yes, they are funky, clunky...

Re: Steel vs Fiberglass

Those curves are bogus. One thing for certain BS did not produce them. These may be the curves that Tad Roberts produced.They used the mast volume and boom? To begin with I do not see any mention of...

Re: Steel vs Fiberglass

I like to be in total control of my shapes. A builder can take my lines and plot full size patterns if he is not going to use CNC and produce a perfectly fair hull exactly as drawn.I want the same...

Re: Steel vs Fiberglass

I'm pretty sure I have never seen a BS boat. I'd probably look away if I did. I like good looking boats.

BS numbers and all talk from BS. I'll post some boat reality tomorrow when I get back from...

Re: Steel vs Fiberglass

Yes, but that says zero about the quality of the shape that was produced. It's just a geometric process. It's not design. So you get a smooth shape. Great. I never doubted that. I doubt the quality...

Re: Steel vs Fiberglass

That sounds to me like a double, radiused chine version of the Nordic 44 I did many years ago. It's all alu .25" plate on the hull and a stout boat. The dodger was not my idea and I was...

If you get the chance could you please snap a photo of that boat and post it. I'd like to know what it is. Does it have a hard dodger? Is it about 45' LOA?

Re: Production Boats and the Limits

You have two stubby little rudders not vertical with no chance of prop wash even if you do want it. It's not going to work very well at all.
