Re: Bolger's power mitihulls
Kristine,
you have probably already seen this. But it comes as close to being
economical, fast to build, resaleable, and seriously useful as one is
likely to find, short of a personal design. One issue that I would ask
about first is that amas are not necesarily good models for powercat
hulls. The deal is for a few thou you buy pre-molded epoxy
glass "pans" that are just glued to whatever square box superstructure
you want to use. Or build the kit, or buy the boat.

Yes I had seen that one but was not sure if it was
PCB&Fs design or an idea someone had and used ideas
of PCB. But it's along the idea I have for a powercat.
I should send Phil a letter and see what he has to
say.

Here is the little power cat St Jan:
http://www.duckworksmagazine.com/01/articles/champlain/index.htm
I'm partial to this design since I quite aside made a similar boat to
my own design, as a prototype for a charter cat, since kids have
enjoyed it. Bolger's was originally designed as a Yulloh testing
platform, if I remember correctly, so the hull shape may not be ideal
for power. Good concept though.

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
different plans.
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
berthing.
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.htmlIt 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
are known.

SBJ#27(Cartoon 3) and BWAOM Chapter 52-pg269.
Also, the queen of them all, Double Eagle, longer at 42 ft.

There are at least 4 Bantams done. The first one was built to the original plans in Nantucket and was written up in M.A.I.B., with a cover photo, a few back. He has since made considerable changes, including the double bottom update. The second one finished was the one Kristine mentions as having be stretched to 31 feet. That one is in Indian River Florida. He first built it the original size, but did not build the folding cabin, and built the cabin top in one layer of 3/8" ply instead of the foam ply laminate. He latter stretched it, but did not build the updated double bottom as he runs only in protected waters. The third one was built, also modified from the plans, and is somewhere in the Pacific Northwest. Bellingham seems to ring a bell in my memory :) I was last in contact with him Last fall when he had launched it without the cabin, anxious to try it out. I assume he finished the cabin during winter, spring?
The fourth one is mine, in Duluth, MN. It is the updated double bottom version, stretched to 22'. It does have the folding cabin, but I did not make the bow detachable as I never plan to be storing it in a garage. I have not been on the Bolger site since last Dec. when I went to Panama for the winter. When I got back I went right to work on the boat, launched in July and have been too busy boating and making some changes to report on it. I just folded the cabin this afternoon for the winter, which is coming tomorrow, according to the forecast. Anyway, now that boating here is done for the year I will try to figure out how to post some photos next week.

I've seen photos of two of them and one was built and
then pushed to 31 or 32 feet as I recall. The builder
didn't like the small aft deck. I think you will find
that one on Duckworks.
I think it's a great little boat.

There are some nice pontton boats, and I can't think of a reasonable
reason against them. they can be designed as extreme low resistence
boats. See my BassAckwards over at Duckworth, which is smaller than
what you sound to be after, and have a look at Bolger Saint
something, which is very simmilar, though mine was designed first.
Also his is a sharpies type, so would plane a lower energy input than
mine, which was designed as displacement only.
I wish I had copied his motor mount, since mine turned out to be too
high.

Granted the Bantam is "utilitarian" in appearance (at least without
its glass house), it is hydrodynamically a pretty reasonable craft.

Could be building shed or storage limitations.

they had a length limit based on either storage or trailering.
I had forgotten about this one... What a cool boat! I'm not sure why
you'd want the bow to fold though. A reduction of 4' from the
trailering length doesn't seem to warrant the structrual trade-offs.
I'd think seriously about adding 2-4' more length to the middle for
some added deck space.
