Re: This may sound like a dumb question, but how long is my Mid 80's Regal Medallian
if yer ordering a cover. believe your tape measure. if ya want to cover 21' of boat. get a cover for 21'. use your tape measure accross the beam too, the widest point. just measure it. aftermarket covers list the width of their covers. take into consideration what yer covering. with my boat. it has a hardtop. this required me to find a cover that was wide enough to cover it. it's 19' but i ended up with a cover for a 21' boat. just barley covers me width wise. about a foot to long on the length. that's ok. my winch is protected too. also get the cover for a boat that closest fits your boat design. a bowrider. a ski boat. a center console. whatever ya got..... sorry, don't know about your boat.... it's usually more about 'how' your boat has been taken care of than what mfg. it is as to how good it is.....
