Re: [bolger] Re: Bantam #654 Construction underway

Not having read the original Bolger article, I cannot say
why Bantam is a -multihull-. But keeping in mind the folding
option from 6 to 4.8 meters on the trailer, the reason for a
tri and not a cat might be that a single folding bow is
simpler to engineer, build strongly and maintain aligned
than any pair of them.

Think of the twist.

Thanks,

You only get two small cabins ont he basis you would
get one small one (slightly larger) on a tri. With
the cabin sprawling from one side to the other you
could have a large cat cabin. The tri has more wetted
surface area, which possibly doesn't matter on a motor
boat, and the motor instalation, could be easier, I
would imagine Bolger would be pretty canny on that.
They certainly make power cats and tri. It just seems
a little odd. Usually power tri have really minimal
floats, if they are going to bear real loads a cat is
better. I am always interested in his motor designs.

Good examples by other designers would be the Gold
Coast Power cats, and
http://www.multihulldesigns.com/stock/21cat.html

I like the 21 footer, though it is a poor example of
one with ample space, welcome to the KHSD world, I
lik the 38" trimaran mother ship also. I have the
floats for the 21 footer already, though they are in
use on my tri. Kurt sure knows how to shape plywood.

That is a question only the designer can answer. But
the designer did 
write an article describing the genesis of the design,
a long saga 
involving a rather unworldy client and a moving target
of 
specifications. The final clients, the couple from the
Netherlands, 
picked up on the design when it was pretty
complete. 
 
The original spec was for a boat for long range,
moderate speed river 
exploration for a crew of one. For one person, one
large cabin makes 
more sense than two small ones.

I think the center hull is to allow full head room without the
extremely high cabin which would be required on a pontoon boat.

I can't speak for PCB but my guess is that, for one thing, the
(relatively) larger and deeper central hull of the tri accommodates a
footwell which in turn provides more headroom than a catamaran bridge
would allow in the same overall height.

This is a very interesting idea. Is there a
particular reason for its being a trimaran, a cat
would seem more normal for this sort of boat.

Greetings Bolgerists, Bolgerados and those aspiring Bolgerites. I am
writing this post on behalf of Captjbturtle, a Bolger builder for a
long while. John Bartlett is now constructing a Bolger Bantam Design
#654. This is a small, tri-hull houseboat designed for Boudewjn
Binkhorst of the Netherlands. Boudewjn has a website which has a
drawing of the Bantam but no photos.

http://www.nauticaspect.com/Inhoud_EN.htm

This design was published in MAIB in a two part series but I do not
know the numbers. John has asked me to keep bolger fans updated on
the progress of the construction. I have tried to post a picture to
Bolger2 in a file called Bantam1.

D:\boatproject\bolger\const3.jpg

The picture depicts the first phase where the three hulls are
constructed and laid out. It shows the removable bow portion to allow
for transportation and storage. John hopes to finish the "pontoon
boat" phase soon and do some testing in the smaller waters around Ft.
Pierce Fl. In the construction of the Bantam John will make several
modifications and has consulted with PCB. These modification include
capacity for a queen size bed instead of the 2 berths, moving the
transom back flush with the stern to give a small rear deck by storing
the gas cans in the exterior hulls and a possible change in the shape
of the cabin to better accomodate the wheel. John is not able
to deal with internet requests for information on the Bantam or the
Idaho like 32 footer "The Turtle" previously discussed on this group,
but I would be willing to act as an intermediate if you contact me
directly by e-mail. John hope to power the bantam with his yamaha 9.9
and his experience with the 32 footer has been very positive with this
motor.
