Small Multihulls for Amateur Construction

I have compiled properties and links to plans pages of small (up to about 25 ft or 7.5 m) plywood multihulls with some sort of accomodation. Dimensions have been converted to metric and rounded when necessary. Strip planked multihulls have been excluded. (* = trailerable, § = hulls demounted or folded before loading on trailer, ?? = no info).
