It really is obvious. Projects in pieces. Develop piece A, develop piece B, test each then stick them together. We are applying this to Subak2 today. The pontoon had been separated from the dinghy to make the repair simple. So today we want to talk about the repair and the pontoon. Maybe the dinghy part is Subak2a, the pontoon is Subak2b. We will think about it, but who knows what came first?

The red bits are some primer paint. The black bit is the gaping wound! Looking into the hole we could see light coming in through the access hatch.

First, the dramas. The hole had to be repaired. This meant putting is a backing piece. Normally then the wood would be filled with some ply of the right thickness and then filled and faired to get a smooth surface. We decided that in order to better deal with probable snags, tree roots on the banks of the river and other such abuses to the hull, some reinforcement would be good. So we will glue a whole long strip of ply along the keel as wide as the hull is flat to make it stronger.

The hole from yesterday slowly dried out once the sun came out. Andrew came down to work on it but it was still too damp, left overs from the launching attempt from yesterday. One thing you learn is that you always gotta wait. Later in the afternoon we could take some old marine ply from intrepid Andrew and glue it into the wound from inside. Getting the wound cleaned up for repair, cutting off thin side bits and getting rid of dust and cobwebs inside, took some time. Then we had to cut more off to get the backing piece in place. Nick made a great suggestion that to hold the ply pressed into the shape of the hull, we could slip it in through the hole and then screw into it, attach some lines to the screws and pull the piece down.

For some strange reason, it worked!

The backing piece is in place, glue oozing. The screws are attached to threads attached to a transformer that is pulling them down, holding the backing piece to the inside curve of the hull.

This is still curing as I write: tomorrow we will add the external reinforcements.
While that cured, we tightened up the lashings on the pipe construction. Subak2b had to be dealt with! Some old pallets were chopped down, re-sized and sanded to avoid splinters and become our rear deck. Or should that be poop deck? We then lifted it – 3 people suffice – and carried it down to the water’s edge. Decking laid on, recliners and paddles, plus PFDs in case it all went awry, we were ready to test.
And it floats!

It floats, we can steer it, it fits right in with the rest of them!
