I checked this out today and both beams are the exact section that is used for the 14 and Wave masts.

Therefore, a 14 mast could be used for the beams and another for the lower mast part on the Wave. I suspect that a 14 mast could actually be made into a perfect Wave mast if cut to the proper length.(not class legal of course...but who cares ?).

Having said that, don't give up on finding the correct parts at a reasonable cost, and nearby.

I'm sure many boats have been trashed with all the rental operations that use Waves.
