Bamboo batten blues - again
Today the bamboo for the battens finally arrived. But they are too thin. Obviously there was some misunderstanding in how to measure the diameter.
So we got 26 canes. 5,4 meters long. (That means about a third of the batten will be overlapped and seized in the middle.) At the thick end they were 40-45 mm while we were aiming for 80 mm at the top and 60 mm at the bottom of the sail. The thin end was 20-25 mm.
The good thing is that we have more than twice as many canes as we need. So we should be able to use battens on both sides of the sail. This will give a slightly heavier sail than to use a thicker batten on the mast side and just something thin to lash on on the other side. Two 40 mm battens are also not as strong as one 80 mm. So I am pretty sure they will bend too much and possibly break in any heavy wind. But we will know more about that when we have tried it. The battens were also different. Some where thicker at both ends, so we will put them at the top.
This is what the battens looked like:
We also brought the sail aboard so we can lash it all together tomorrow and cut the rest of the running rigging, like lazy jacks, sheets, sheetlets and downhaul. I added a mast lift even though it isn’t in Tom’s plans, to help the lazy jacks hold the sail up at the forward end. It also gives an extra line up the mast, that might be handy to have.
Let’s see what happens tomorrow!
