A. We would agree, there are some pretty poor installs out there, a lot of which is caused by the weekend DIY warrior. We can respect the customer who wants to save a little money, however there are some things better left to the Pros, and Spider Net Installation is one of them. Another cause of ill looking nets is the material of which they are fabricated. YachtDocs uses a 90% density commercial grade shade cloth with a patented weave design allowing for a taunt stretch every time and breathability so heat retention is not an issue in the boathouse. Beware of the solid material, which is nothing more than a tarp, it does not breathe and is very prone to ripping in moderate winds.
