What anchor??

[The Gurnard]

Yup..I vote for the bruce type anchor too.. I use one as a main anchor. I kg will do with a few meters of chain.. A SIB is not a heavy boat so I find I get away with this set up.
However ...I love my small grapnel too and wouldn’t be without it. Agreed ..I would not trust it holding if thrown overboard.. but I use mine on a short rope tied to the painter. When I land..its brought ashore and I manually jam it under rocks, in cracks..tie it to piers etc SIBS always been there when I returned too..so they are not useless used that way.

Another recommendation for a bruce anchor. Like mentioned previously, you don't need a big one for a SIB, and it works well for all sorts of bottoms. It has no sharp edges so it is safe around inflatable tubes. I use a collapsible bucket to organize my chain and line, and find that I can store a bruce anchor with the buket just as compactly as I could with a folding grapnel anchor.

I'll find some photos to post later.
