I am not sure I see wood or a problem with the first photo
of the rudder
. It looks like an old and poor "body putty" patch in a later photo
that would best be ground out and fiberglassed. I am not sure of the location or function of the first split teak
trim photo, but that looks ragged enough to replace. If you tolerate the look, some of this trim can be done with plastic composites and such. As for the compaionway slide and the cracked teak
gulide. I would suggest that the slide and the trim guide be placed on top of a polycarbonate strip that is adhered to the deck
. This polycarbonate will provide a smooth and quiet slide. A piece of rubber bumper inside at the slide impact point at full open position can be a good addition too. You could cut a new piece of wood, but my choice with this same problem was to use Starboard plastic as in the photo below.
The black guide to the companionway
and the handrail is Starboard. This can work with pieces that are not exposed to great flex. The Starboard will crack before much bending. Also, it won't work for those that want to keep a traditional look.
