power? Those that reasonably could have auxiliary power, though not
shown as such?
The designs index lists about 9 to 10, or so, depending how you
count them. A few are studies/earlier plans that became somewhat
There's Bolger indications there are more than have been published,
or are in the index, eg the Bolger vee-bottom, inboard, stay
sail "Cruising Cat(-amaran)" in Derek Harvey's "Multihulls for
Cruising and Racing". It had moderate beam as reportedly Bolger
reasoned that gave a less jagged stability curve and compact
There used to be earlier this year, current photos of a Bolger 24'
aquaculture power catamaran built at the Old Wharf Dory yard that
was still a goer: http://www.oldwharf.com/history.html It had
moderate twin ob power, vee-bottoms deeper at the bow and flattening
astern, kinda beamy hulls with lowish freeboard, sheltered helm, and
good speed on the plane I would think. I think there's a pic in one
of the bolgergroups.
Seems to be only 5 straight power multis: Bantam, Fishcat, Trashcat;
and the two Power Cats, #480, and #598, the first of which the Old
Wharf Dory yard example is likely to be, and the second may be a PCB
supplied version of the CSD Fishcat #469... making it 4 in all that
