l need to replace curtains in the salon (living room) of our used boat.The side windows go down to a point, sort of a triangle shape, but they need to be ''full'' or pleated. I am not sure how to measure for that because of the shape.

r u making the curtains yourself?
then spotlight or some fabric store

otherwise u should be able to find companies on the internet
i know of a place called sheets ahoy in sydney & queensland (australia) but l do not know if they do curtains

you could also contact a sea ray dealer because any bets they could arrange for cutains for you

i know someone who bought a second hand fairline & needed an extra bimini so they just contacted a fairline dealer & its all been organised (even though the boat is not a current model)

i hope this helps :D

searay dealer parts department or have a local canvas dealer measure and make.
