Crab Claw Tiki 26

by Steve W

Jul 12, 2018

I'm planning a Crab Claw rig for my Tiki 26 and have some questions for those with experience, especially Hans Wakataitea. I'm not trying to beat Bermudan performance, just make a good basic, affordable cruising rig. 

1) Best method of attaching the sail tack - directly to the bottom of the mast (Wakataitea) or with the tack forward of the mast (Ontong Java) ?

2) The angle of the sail spars and the plan shape of the sail at the tack - 60 degrees (Wakataitea) or less ?

3)Curved or straight edges to the plan shape of the sail - straight or curved spars top and bottom?

4) Jib, no jib?

5) Best method of reefing?

I've spent a lot of time searching the net and found lots of very good stuff and now it's time to come up with a compromise design out of all the info that I can actually make and use. It will be very low budget. I'll probably make the mast and spars unless I happen on a lucky find that will suit.

These various differences would be interesting to experiment with. I have good sheltered waters to get plenty of experience with the rig before venturing further.

Thanks for any help,

Steve

    Hi, Eric and Delphine,

    Thanks very much for your reply. I had seen some photos of your boat before, but had not found your blog - now I have read lots of it, very interesting, great stuff.

    I take your point about straight spars. The curved crab claw sail shape looks beautiful, but perhaps practicality wins the debate.

    I don't quite understand the new reefing system you mention " we will unzipp the top of the sail" ?

    Best wishes for your voyaging,

    Steve

    Hi ,

    I mean that I will remove the top of the sail to lower the center of the sail area.

    The polynesian people unsew the strip at the top of the sail to reef..

    I will do the same but instead of sewing and unsewing, I will use a zipper.

    Hi, Eric and Delphine, ah, yes, now I understand. A clever idea.

    I'm now looking at the possibilities of a bipod or A frame mast - seems to have some advantages such as being able to move the tack of the sail fore and aft. One of the good things about the Tiki 26 is the size - I can experiment on a manageable scale and not spend large amounts of money, too.
