What abouut Masts, booms, yards and other spars?
To keep costs down it often makes sense to lash sails to spars – it means you don’t have to buy mast track or other fittings to attach the spars. You can simply run the ropes to tie the corners of the sail in place through holes in the end of the spar. However there is a small chance that the tension forces of the rope can split the end of the spar. Wrapping a couple of layers of fibreglass tape prevents this from happening – the threads of the fibreglass take the splitting loads. The hole is later drilled through the mast tip in the middle of the fibreglass reinforcement. This approach works well when the rope will tie to the end of the spar. If the rope ties somewhere other than the end you will need to attach a fitting.
