I also began the third generation mast for the trusty blackhall skill in Fairfield CT. I gave into the temptation to hide some carbon fiber in the sitka spruce. it should look traditional but will be super stiff. No more boom snapping on long island sound! Per JP Bradley standards the cf is feathered in to disperse the load around the mainsheet connection 2/3 the way along the spar. notice that the boom jaws have a surprise inside as well.
