Checked on my boat this weekend and noticed Rats had moved in . They have chewed on almost everything , seats , fishing line ,spare reels, Binoculars , downrigger clips Etc. A great big Fing mess . Hopefully wiring hasn't been touched . Heard they were bad this year. 4 traps set and 4 homemade ones . If your boat is put away for the winter check for vermin !
