I’ve had my eye on these but they are too expensive

As Adam announced I did successfully make the 2300 NM crossing from Hawaii to Oregon and then another 95 NM up the Columbia River without incident. It was a 25-day journey. I was happy that the winds were light for most of the way as to not challenge the mast repair. I experienced several days of 18...

I was finally able to finish the Vaimana’s mast repair on our spring break. I added the final carbon fiber layers (approximately 1/8-3/16”) and faired it with West System epoxy and fairing filler. I did a final 2 layers of fiberglass cloth over the whole damaged area, then a skim coat of more faring...

First layers of layup. I alternated about 3-4 layers of unidirectional then (1) layer of twill. This is about 10-12 layers.
Ran out of time and ended up hoisting the mast back onto the boat. I’ll finish up with about another 15-20 layers and some grinding and fairing.

Repair sequence: 8.jpg Mast laid out on dock with 20” broken zone removed. I made small stands with wheels to support the mast along the length. 9.jpg Ends tapered at 16;1 Sleeve dry fitting. Wax paper around messenger lines. Sleeve is 3/16” thick and 60” long. 10.jpg Glued up with High density fill...

5X edge grain (you can see some voids here too)
5X Cracking 50X (circumferential cracking thru the fairing but not thru the FG)

Here is a status update for the mast repair: I cut some samples of the mast and took pictures of the cross sections along and perpendicular to the unidirectional fibers. The wall thickness is about 0.291” thick the carbon fiber portion is 0.215” thick. It appears to be an all unidirectional layup. I...

Correction, the above analysis were done with a 500 lb load at the tip not 1000 lbs. Below is the mast with the factory sleeve and 1000 lb load at the tip. Don’t worry about the red its still about 1/3 of the ultimate strength. 0D40FE72-C9C2-4689-9A4C-D28BA37EF69A.png These next two are just closer ...

BTW anyone know where I can get some of this aluminum sail track?

Aloha Adam, No worries, just needed a little push. In the break zone on Vaimana’s mast the windward fibers pulled away from the fiberglass circumferential winding (blue in photo). The leeward fibers folded over. The forward 1/4-1/3 of the mast looks like it has a lot of fiber pull out associated wit...
