Could you explain to me why this type of cover is apparently so popular in the US?
I lived in The Netherlands for 3 years (The Hague and Eindhoven). The amount of snow that The Netherlands sees in 10 years is roughly equal to the amount of snow in a one to two storms here. This year in the Greater Boston, MA area we've had about 1.75 m of snow this season already. That much additional weight on the boat could cause the deck to fail, especially if it snows and then rains and then there are several partial thaw-freeze cycles. It's not the rain or the snow the that's the specific problem, it's the damage that can happen if any water that finds it's way into hairline cracks and gaps freezes, expands, and then causes the cracks to widen, which increases the potential for water migration into the deck core.
