Re: how to get a boat rub rail off?
you just have to take the rubber out of the rail , there you will find 14 thousand

screws or rivits that hold it on.
you will have to drill them out as they probably will NOT just screw out.
it would be a good idea to put some cross braces in the hull to keep its shape , or you may not get the top back on !!
check with these people , they may have the NEW rubber , or they can make it for you

then you have to figure out if it is a shoe box joint (the top slips over the bottom and then the screws or rivits hold it together)
or it may be glassed together on the inside then you would have to use some thing a hack saw blade to cut it apart.
hope this helps
