Row out to you boat in the coming weeks and you will be dive bombed by seagulls that have made their nest on the boat you happen to be rowing past.
I have mentioned before about this time of year and the need to get down to your boat to keep any nesting birds away, they will quickly find a less used boat and you will be safe.
One poor customer found this out, although he waited till spring this year after a year of bird action in his mainsail. He was very embarrassed about the sail, but I assured him I had seen worse, turns out I lied and this sail, (beware pictures below) is the worst I have seen.
Seaweed, sticks, dirt, poo, even old eggs had given this sail a patina that almost looked artistic. Too bad the sail was nearly new and worth $15,000!
It might be the first bird sail of the season, but I doubt it is the last.
