Re: Steel vs Fiberglass

Jon:
No, they use a bag several times before chucking it. On the heated glass table I think a bag would last many panels. It's dragging the bag over the hull plug that buggers it up.

Re: Steel vs Fiberglass

BS will never get it. He is a little man with a very narrow point of view.

Me? I'm having fun today working on my new 70'er for the client in Japan. This is a project of the type that BS will...

Re: Steel vs Fiberglass

My friend Emil Dopyera circumnavigated in a boat I re-rigged as a schooner. He had a great time and came back to me for a custom design.
Emil's Dad and Uncle invented the Dobro.

Choice of draft is very personal. If you know you will spend a lot of time in draft restricted areas then go for a boat with less than 6' draft. If you THINK that maybe, one day you might be in a...

Re: Construction methods (and their trade offs)

Almost all rudder posts that have been built in the last ten years have had a s.s. sleeve at the bearing. CF does not like to be "notched" so you let the SS take the bearing load. This is common...

Re: Construction methods (and their trade offs)

My four carbon cutters have all their tankage in the keel. This helps to give us a VCG 1.67' below the DWL This is unheard of in most cruising boats. The tanks will not be integral but will be...

Re: Rudder Upgrade; Performance Tips Needed

Nope, rudders can be very different in shapes and effectiveness.
Can you post a pic of the rudder you are talking about.

Or, buy my book and go to the chapter on rudder design.
