Three hulls, one trimaran

Six hours of work in the last two saturdays, messing around with diagonals and the like on the aka system. Once the beam system is on the boat, we had to convince ourselves that it's impossible to "close" it to better than, say, 1 cm. So, after much rimugination, today we decided to kill the scientists and to assemble the boat as it is. Well, it worked! Here's the whole boat

Of course it started to rain in perfect time, so we had to cover the beams (not yet fiberglassed) with plastic. Neverthless, we tested the retractable aka system with the real amas (floats) and it worked so well that we decided to open a VERY good bottle of prosecco to celebrate.

Total work time to date: 566 hours

Back to it

After almost one idle month (boatwise) here we are again. Three hours today to fiberglass the bottom side of the two akas.Here's Cinzia cutting the fiberglass to size

and here is the complete job after the second resin coat (three hours after the first coat).

Fiberglassing is unpleasant. Air bubbles appear all over the place; there's always an unseen splinter which will stand proud under the wet cloth; rollers and brushes leave residuals. Anyway, fiberglassing is not critical for these pieces so it should be ok.

Aka alignment

Two hours last saturday to check the alignment of the aka system. The whole stuff is accurate within +/- 5mm and we'll possibly have to slightly modify a few bolt holes. Here's a pic showing all beams cleaned and ready for fiberglassing

and here's another view of the whole aka system

Deck seats (3)

Last saturday we worked two hours to glue up the various components of the deck seats.
Here are the two seats with the inner reinforcements. The wooden beams will rest on the port and starboard deck of the cockpit.

Those are the two beams (2x4 i.e. 45x90 mm) that will longitudinally join the forward and aft akas on each side. The reinforcement glued at the ends are there because we'll have to drill holes there for the 10 mm bolts. The outer side of the seats will be epoxy glued under those beams.

Total work time to date: 552 hours

Deck seats (2)

Spring is coming in at last, so it's becoming more pleasant to work in the garage. We worked 2 hours this morning to cut out all the pieces to build the two deck seats, which are 2 meters long and 75 cm wide each.
Here's a view of the to panels of 12 mm thick plywood cut to size after being stacked

and here's yours truly relaxing to give you an idea of the size of the seats

We also cut all the longitudinal beams that will be glued to those panels next time.

Deck seats (1)

During the week we spent two more hours to complete the coating of the aka bolt holes with silica thickened resin. This morning we worked two hours: we took the vaka outside to check again the aka system and to take measurements to cut the two panels of 12 mm plywood for the deck seats. Those will be 199 cm long and 75 cm wide.
Here's a view of the two akas with the doubler

and here are the two deck seats ready to be cut to size
