We have a 1985 two stateroom 36' Kady Krogen Manatee and want to get a replacement mattress for the forward stateroom. I took measurements before leaving the boat but am now wondering whether I need to check my template by taking it back to the boat. It is curved to match the port side hull. Is there any chance we have another Manatee owner out there who has done this and might already have a proven pattern or measurements that I could use to double check before ordering...or even order from the same supplier?
