Dear list,
I know I should already know this, but I do not.
A builder has suggested that in lieu of a steel hull and aluminum
superstructure, I should consider a cold molded epoxy hull.
Now, I thought I knew what "cold molded epoxy" hull was but Ron from
the list says it is different.
What I thought I saw being built at one shipyard was a mahogany
framed and planked hull being incased in epoxy.
Ron tell me that is not cold molded epoxy building technique, but
could be a viable technique, although quite heavy, with a fuel
consumption hit.
So, as I understand it, a cold molded epoxy hull is made of of strips
of wood bonded together and then, in the best of the building
techniques, vacuum bagged while epoxy is pumped in to finish the hull.
The latter technique makes for a strong, but light hull. The former
technique is not true cold molded epoxy, but could make a strong, but
heavy hull.
I can see some obvious advantages over steel (no rust, no sweating,
no electrolysis) but if this is such a great building technique as
the builder espouses, then why is it not used more often..
Disadvantages: if I hit the rocks, the steel would be better....maybe?
Help, please. If you answer privately, I d intend to summarize what I
learned and repost, without attribution.
TIA.
Lee
