Mine is a '93, I took it all off last winter for the same reason.
In hindsight, I'd agree with the first two comments, it's better to sand and varnish them in place.
Having said that . . . none of my screws were hidden. The "eyebrows" are just glued on, one of mine was falling off when I started, the other was a really slow process.
My original plan was to make all new boards, but there are some interesting compound curves on especially the bottom pieces - the threshold if you will, and when I got them off it seemed really only one of them was broken. I tried to squeeze epoxy into the crack, but I'm a little skeptical - If I end up redoing something - it will probably be that.
I was able to fill the broken bits with thickened epoxy, coat all the pieces with two coats of epoxy and several coats of varnish and be ready for a spring launch.
I swear I took pictures of the before and the during, but all I can find is the after.
