Hello Rob,
How are your currently making mast for 12 M Haryproa ? Is three any way that it could be resin infused, either as one piece or in a mold for a section of mast or stays that would be glued together to form mast ?
One thought I had thought of would be to make a mold for 1/3 section and make three sections that would be resin infused and then bonded together. It could then get additional uni added as needed and then a final carbon sleeve (or two) added to give additional strength (+ - 30 to 45 degrees) and lock all three sections together as on unit. I would also like to use vinylester resin with carbon fiber which may be controversial. What do you think ?
Another method would be to use a solid or hollow foam core to mold everything on.
What is your current thinking on building mast for Harryproa ? Please put pictures up of you next mast project. Your web sight has little information on how to build mast. As the free standing mast is a big part of building a Harryproa I expect others would also be interested to know what to expect before committing to building this large of a project. I assume you plans for Harryproa include building the mast, is this correct and have you updated them recently for easiest construction method ?
Happy sailing,

PS
I came across a reference to you as a "Proa Genius" by Kirt Hughes in his manual on rapid build composite construction. (Also other references I will not repeat from other designers)
Could this building method be used for your Harryproa's, combining flat table layup with strip construction ?
He also has a proa in his portfolio that has rig that looks the same as your harryproa rig.
Did you have anything to do with this design ?
