Thanks for the reactions, everyone! Especially for that link to the Nautylys site.
MedSailor, did your friend attach that outrigger to his canoe by himself, or did he buy it like that?
And I was wondering, what kind of material should an outrigger be made of? How heavy should it be compared to water?
Looks like it should be rowed' not sailed.....Something Hawiain????(or just a secret rum runner)
It actually does have a sail, but you can see only a little part of it on the picture.
