Re: Closing seacocks
20 seacocks Minnewaska???!!!!!! No wonder you don't close them all! That's a full-time job!
On my boat I have tried to reduce all holes in the hull and I've got it down to 4: washdown pump intake (always closed except for the few times I've used the pump), head sink outlet (always closed when sailing), galley sink outlet and engine raw water intake. All are easily reached without having to move stuff around. I close all of them when I leave the boat. I also removed any through-hull transducers and paddlewheels (speed) in favour of 2 in-hull fishfinder transducers. Speed (SOG) I get from my GPS, although I miss the speed through the water data I used to have. I feel more comfortable leaving my boat now. Installing a composting toilet and removing 2 through-hulls gave me great peace of mind, especially after reading somewhere that toilets are the number one cause of boat sinkings (siphoning water back into the boat).
