Hi.Tim, some pictures of the internals as requested.
The hull before any top work done, it was resin coated and a layer of 25 gram glass added, inside and outside.
I used a lever arm servo rather than the winch drum type shown on the drawings.
The steering sevo is suspended from two beams across the top of the hull at the gunwales, the fin box and mast box are the only conection between the deck and keel.
Regards.
Eddie.
