I did a fairly serious
renovation to a 26-foot Telstar
Trimaran. It all started by converting the V-birth to the
head and
storage area. I built a new
galley where the old
head was and lengthened one of the settees and added a small nav station where the old
galley was. I mostly rewired and replumbed as well. The total
price tag wasn't all that bad.
One thing I found very helpful was to use a grinder with a thin blade instead of a saw to cut out old fiberglasss. New bulkheads and
flooring made with
plywood, mat and
epoxy turned out well. The new galley counter was made simply with
plywood, laminate and contact cement as was the chart table and
salon table. I used oak trim stained and varnished on both.
The end result may not have been quite professional, but it was functional, looked okay and cost a fraction of what hiring professionals would have cost. I also really appreciated knowing exactly how everything was put together.
The mat I got online. The
epoxy resin directly from the West System folks Gougan Borthers (sp?)(though I've heard they don't do that anymore.)
Paint, hose and a small
holding tank from a
marine store and a composting head directly from the manufacturer. Most other supplies I purchased at a
lumber yard.
I was very pleased with the final results and would do it again.
I'm sure there are more qualified people who will have further input.
