We do not have very many rainy days while we are underway. If we know bad weather is imminent we stay in port. Sometimes there will be a rain shower in the forecast but as long as it is brief and does not pose danger we will sail on.
The original section of our bimini leaks when it rains making it a wet ride. Not fun. Another project for another day. The good news, the boat is getting a quick bath.
By the way, that thing on the right that looks like a surfboard is the Porta Bote we use for a dinghy. It is folded nicely and lashed to the rails. The black blob is our trash. When we are away from port we (like all other cruisers) carry our trash to dispose at the next port.
