I've buitl one myself.
Due to the obvious space limitatons in Fulô (my Piver Nugget 24 trimaran) it had to be quite small, but if you care enough to scale up the plans and fancy building something yourself this canoe makes a perfectly stable and very light (quite a lot lighter than the plastic types) dinghy that you can even tow arround in windless days with almost no drag.
I've built mine for arround 100€ in 4mm plywood, epoxy, fiberglass, paint and a couple of days of work and it wheighs arround 20Kg
are the plans
And here are a couple of pics of my brand new dinghy:
are a couple more of the building process
Hope this was of any help!
