Navaltoday.com is reporting the third of a planned five SWATH (small waterplane-area twin-hull) patrol boats has been delivered by a shipyard in Riga. This is hardly new technology, the Coast Guard Yard built the 26.7 meter, 228 ton SWATH Kaimalino in 1973, but it is certainly an unconventional choice.

SWATH always seemed to have great potential, but has not found many advocates. I’m wondering what disadvantages they are aware of that are not obvious.
