Sorry this one took a while to write up, I've got no excuses as I was on holiday and doing very little! To make the cockpit tent I decided on a design first. I had several choices to make here, one was using GRP rods to give a rounded shape. I may still do this longer term but chose to go ahead without for now as it seemed roomy enough without, and stowing them would be a problem since they would either need ferrules or be 3m in length. I then made the decision to fit over the boom, using it as a support. This is not just easier but also practical. To fit under the boom I would have needed to sew in some kind of ties to attach it to the bottom of the boom which would almost certainly have introduced leaks, but also would have meant I would lose the boom inside as a wet locker for hanging oilskins on inside the tent.
Once the design was decided upon the rest was easy. I measured the boom from the end at the topping lift forward to the first lazy jack on the stackpack. Since this cannot be removed easily the tent has to go around it and therefore this is where a split needs to start.
When all of the seams are in place, use some eyelets (hipkiss kits are ideal) to put the shockcord through for fastening. I used 5mm shockcord in black with 5mm black eyelets and black hooks as they contrast nicely with the bright white of the tent fabric. In all this project cost under £20 although I was still using up the venture tape from the stackpack project. Be sure to use UV resist thread, I found some polyester stuff in Fabricland which seems to fit the bill but time will tell.
