Analysis of information sources in references of the Wikipedia article "Trimaran" in English language version.
In contrast to double-outrigger canoes, however, [trimaran] floats are often quite large and buoyant and contribute considerably to drag which slows the boat. [...] The Pacific canoes are notably more narrow ([length/beam] ratios of about 10 and 13 respectively) than the trimaran (ratio of about 7).
Seaworthiness is implicit in the ability to make such voyages. A specific point illustrating the latter is the technique known to Caroline Inslanders for righting their canoes after they have capsized at sea. In brief, the mast is rigged from under side of float to a sheer legs erected above the bottom of the capsized boat. Four men climb quickly up the inclined mast, their weight forcing the float to submerge to a point directly underneath the main hull. Past this point the float's own buoyancy takes it back to the surface in righted position whereupon the canoe is bailed, rerigged and continues on its voyage.
