Painting The Inside
After applying two coats of Interlux Epoxy PrimeKote 2-part primer, I lightly sanded and cleaned the hull as prescribed, and applied the first coat of white Interlux Perfection 2-part polyurethane high gloss topside paint.


Mixing 2-part paint with thinner and then with 2-part flattening agent requires different part ratios and a specific mixing sequence to obtain the desired result per Interlux's instructions. I created a spreadsheet to calculate the combined ratios to mix only the amount of paint I needed.
Finishing The Deck Frame
In preparation for the deck, I had to build up the deck frames to ensure the top surface of the deck frame is leveled with the sheerline. This work included building up the king plank, the breasthook and the deck beams.
My mistake was not to interpret the drawings correctly when I fitted the deck beams, the breast hook and the king plank, although the drawings were clear.

Western Red Cedar strips added over the deck beams...
...and 30 mm x 4 mm marine plywood over the spaceframe tops.


Next, I cut two 6 mm plywood pieces to fit between the jib cleat and the aft deck beam on the starboard side. I glued both pieces together with epoxy resin and colloidal silica. Then, I shaved the starboard plank angle and fitted the 12 mm plate with more epoxy resin and colloidal silica. The same process was followed on the port side.
I decided to add more curves to the deck to smooth our her lines around the aft deck beam where it intersects the king plank and where it turns around towards the jib cleat.



The Deck

Firstly, I measured the distance between the aft end of the king post and the forward edge of the breasthook where the deck will end. I added 1 inch to that dimension and cut the plywood sheet across. Secondly, I centered the sheet of plywood along the king plank leaving half an inch extra aft and forwards so I can then plane it to shape after it has been glued in place.
Jeremy Deacon, fellow Merlin Rocket sailor and builder, recommends this procedure. This way not only does one have a slight margin for error but one gets a really good straight join when doing the gunwhales. Jeremy has also done several top-notch boat restorations. Thank you, Jeremy!
Once over the deck, I secured the foredeck with clamps and using a pencil I traced the outer edge of the gunwhale underneath. Then I moved the foredeck to a temporary work bench protected with poly to avoid damaging the face of the plywood that will be exposed. I traced parallel lines to the gunwhale lines, half an inch apart for cutting the foredeck with an extra margin for error.



Next, I cut the second 4' x 8' sheet of 4 mm marine plywood in half along its length, ending with two 2' x 8' pieces. One for each of the side decks.
Later, I clamped the two 2' x 8' pieces over the side deck and over the transom.
For tracing the outer gunwhales on both side decks, I followed the same process as with the foredeck, then adding a parallel line about half an inch apart for error margin.
Same process with the inner carlin lines except some careful foot work and balancing inside the hull was needed to trace the pencil lines.
