My Puck 1990 had a vicious draught through the ventilation louvres. I understand the need, but a force 10 gale is way too much.
After much searching on t'interweb I found some small hit and miss louvres that don't stop the draught, merely reduce the force of it.
I couldn't find one big enough so brought two smaller ones that cover the whole area.
