My amas are unprotected, and so are my bow and stern rails. Only my cockpit and center hull cabin/decks are covered... One of those compromise decisions between what's ideal and what's practical.
I was on the boat yesterday in the rain and everything under the cover was also wet from dew. The boat surfaces were cold, air temps warm and dropping throughout the day, it was raining and near 100% humidity. Then last night it went below freezing again. Not good.
How do you cover your tri?
