Didn't use your boat over winter?

tIf yes is the answer, then there is a high probability that your boat has been an excellent nesting site.
We have already cleaned numerous sails and canvas that have nurtured some new chicks, the Vacuwash process is excellent at removing most of the evidence.
Pictures of bird stained sails are upsetting, so instead in this post I will give you a cute picture of a seagull chick so that you don't get too mad when the sticks/mud and other crap falls on your head as the main is hoisted.
