I believe that what you are seeing is the layers added between his laminate and the vacuum bag. He used a peel ply and/or a release film. This absorbs excess resin extruded during the vacuum process along with keeping the mast from bonding to the vacuum bag.

Both sides of the mast are the same (symmetrical).

Yes Gato built the track (figure eight tube) see his notes in home building forum.

Bobcat is correct on the use of peel ply.

Note on Building a DS 12.

The carbon mast is an option only. Gato went this route due to a lack of suitable or cost effective aluminium masts in his region. The standard drawings call for an aluminium mast. Any section designed for a two crew, one on trap dinghy or small non trapese cat will have approximately the right bend charcteristics. Long term I hope to have a standard mast available, however, the cost of international shipping means that the rigs will need to be shipped in large batches to make them cost effective. So it will all come down to whether people make this F12 concept a success.

Sorry for not answering myself, I have been off line for the weekend. Well, once you have used peel ply you don’t want to live without it, saves a lot of sanding and all the “impurities” from the epoxy is coming off with it. There is no need to make this figure eight tube, you can as well take down the hale yard in the same tube as the bolt rope.
I decided to have a go for the spar as I have some very bad experiences whit single alu spars shipped from abroad, and just the transport is more expensive than the whole mast homemade. Still the big test for this one will be on the water, so before you start to build let’s wait for that one.

Gato,

time for a career change, as it appears you've mastered the role of a thriller author. You've got us all hanging on the edge of our seats waiting to see what happens next.

There has been things going on, but I have had problems with internet connection, so the blog has been suffering...

On my way out to the island of Brändö with the sail for the cat in my car, so hopefully the first try is not so far. It will also soon be time to summarize the building, and it seems that we are well within the goals set for the class. I have spent some 150 hours of work on the boat but that includes making everything at home. Of all the boats I have made this is the one where thanks to Scarecrow it has been possible to build everything at home.
For the costs all included even the beer it stays at 1100 Euros, the things bought to the price accessible to everyone in Finland. I will get back to the final weight of the cat later, it’s should be quite on the mark. Hope to find a little bit faster connection to be able to upload pics the next week.

I don't know yet what Gato has built, however, the rudder stocks as designed to be fabricated out of bent box section ali tube as was standard on most A cats until about 8 years ago.
