I finished the cockpit floor and sidewalls. They are positioned and glued into their places. Concave joints are reinforced with glass tape. The S/S axis (f8mm) are made also, I fit them to the keel lift fittings.

Some winter months are gone… Unfortunately I had other task to do. But now, I started the work again with the cabin side windows. First I designed the size, quality, form of the windows. It is important to fit the mechanical and waterresistance regulations. I choose 2 times 3 mm thick glued 1st class glass with secure folies on both sides. The glasses are held by EPDM rubber bedding. The other side of EPDM rubber profile is held a glass cloth reinforced plywood – which is glued to the cabin side plywood by epoxy.
Cabin top is glued by epoxy (Sicomin SR5550 with SD 5504 UV stable hardener) resin and sanded. Every hole of screws is also filled with epoxy resin, Silicell and Treecell mix gave me high density material. Edges are strenghtened with glass tape the same way as inside. The deck top is not glued yet, because I have run out of resin. I had to reorder from Bonn, Germany.
I glued and reinforced with glass tape the cabin top and deck side panels. All panels are shaped (scarf) by plane before gluing. For fast joint I apply nylon cable tie, but before gluing I change them to copper wire.
First I placed the center panel. The side panels are scarfed and joint to the center one. I started the gluing with the inside of starboard side panels, the outside will be reinforced with tape after the inside works are done.
Before I start to place the deck top and the cockpit floor with the cockpit sidewalls I wanted to place as many fittings as I can. Furthermore I wanted to paint the hull inside before istallation the tops. (They will be covered with plastic film foil to prevent dripping of resin from the top during gluing procedure.)
Boxes for batteries, fuel tank, gas bottle and others. All can be opened from outside of the cockpit and separated from the inside of her:
After finishing keel foil shape – with placing two POM (Poly-Oxy-Methylene) tubes into the top of them – I could install the keel box into its final position: between bulkhead “D” and “E”. The two tubes made for supporting the d=12 mm S/S rod that has been pushed into the ‘horns’ of keel foil across the keel box when keel is lifted to down.
There are two S/S316 tubes on the bottom of keel foil also to drive the S/S bolts supporting beaver tail torpedo bulb sides.
I drilled the necessary holes into one side of keel box according to the place of the hole on the keel foil, and after installation I drilled the other side holes using the opposite side as a ruler.
To install the gas bottle to the appropriate position (there is a regulation by the authorities that the gas bottle can’t be placed into the same airspace as the berth place, so it has to be separeted) – I had to make a special box that can be accessed only from outside (cockpit). Therefore I drove the gas pipeline from the cooker place to the aft where the gas box will be set. For this reason I glued small Mahogany plates into the bottom of hull inside. Clip pipe mounts to be drilled into the plates, not to the hull.
The oblique door frame between the bulkhead “E” and “F” (or from the keel box to “F”) was built in also. The front and rear side of the whole keel box construction has got Mahogany veneer layers – just for the spectacle.
The cockpit/deck stringers are also ready to glue into the slots of bulkheads (pre made in summer of 2010).

I could start the setting of keel box after finishing keel foil to the appropriate measures and forms. Keel foil consists solid Mahogany hard wood core (see: hard wood core) covered with unidirectional clothed carbon sheet and many layers of epoxy resin, and finally a glass cloth embedded in epoxy (see: finishing keel foil 1. and finsihing keel foil 2.)
