Beneteau Oceanis 351 Titchmarsh Marina, Essex, Engl
Hi, the hinged rear seat of my Oceanis 351 slowly fills with water - even when vertical for 99.9% of the time.

I have taken action to empty it ( once having removed the seat ) - but am curious as to what causes the issue. I wonder if anyone has come across this too - and what they did to address the issue ?
