I know it's a depressing thought, but we've decided to invest in a winter cover for our Troll this year. We have a 2017 Troll 540, and left it naked last winter, but feel that it would be better to have it under cover this year. So, what are your recommendations? Tailor made or off the peg? The compound we keep the Snug in has very little protection from the wind blowing off the Forth, so can a cover rub and scratch the bodywork if it is buffeted about? Never used a cover on our previous WWBs, but feel a lot more protective of our lovely Eriba......
