On a four hour outing we had her up on plane for about a half an hour
besides just crusin'.

We are still fine tuning the batteries/controllers and props for best
performance.

Actually I checked this out before we started to build the boat. African
Mahogany is not endangered or in short supply since it is actually several
different species all classified as African Mahogany. I have been in the
wood working business for over Twenty five years and researched this
extensively.

Besides I know of no other specie that would work for this boat. We needed
both light weight and flexibility to make the shape come to pass.

If you know of specific issues with African Mahogany I would like to know
about them.

Thanks for the input

Tom

Hello Delburt,

Please do not let my post belittle what you have accomplished.

I am simply obsessive when it comes to nomenclature ,in regards to wood. It
is best , in my opinion, to know the wood by it's real name.

very best regards...Ken

No harm done Ken, I am always open to new information. The Usenet has been
a great source of information and also a way for me to help others as well.

This project is the coolest thing I have ever built, and I have worked in
many multimillion dollar homes as well as some large yachts.

The greatest challenge to me was honing my skills in both design and
construction of this boat. We conceived the Idea a little less than a year
ago, made the first sawdust on Feb 23rd and splashed her on Aug 23rd same
year!

Tom:

Beautiful boat - cool website. Your design in very reminiscent of Ken
Hankinson's Barrelback 19, see: http://glen-l.com/designs/hankinson/barrelback19.html

You indicate that the boat will cruise 'all day' at "hull speed."

This term is generally used for displacement boats. That is, hull
speed is generally not applied to boats whose speed is not limited by
wave drag.

Be that as it may, do you mean that your vessel can cruise all day at
5.52 knots (sq root 17 X 1.34)?

Are Runabouts generally used by folks who'll be content with a few
quick bursts of speed? I mean, haven't classic mahogony runabouts had
small block V 8 engines for the 'go-fast' - as in "go-fast-all-day"
crowd?

Not trying to be a naysayer, just curious as to your motivation.

A year ago after I finished my strip planked 13' canoe using teak,
mahogany and red cedar I hatched the idea of doing a 16' barrel back
and using a 40 hp (36 volt) electric motor using the same hull
building skills. I have the plans drawn but its on hold. I still
plan on it, but my wife is trying to talk me out of it. It shouldn't
be but about 3 times the work as the canoe and strip planking is not
really work anyway. But the Cedar would be my choice because it is as
beautiful as the mahogany AND its lighter. No, I am NOT saying yours
is not Beautiful, it IS, Its awesomely beautiful. But I will go for
the lighter weight so I can carry more batteries.

Thanks for your response Mike.

While we are hoping to see better performance down the road, there are many
lakes that not only do not allow gas motors but also no wakes. This is our
initial target. We are just offering a way to cruise and look better than
the current choices in electric powered boats.

We Have had her at several boat shows so far and have received very positive
feedback. Basically we have a cocktail cruiser with attitude!!

As battery technology improves, several new types are currently in
production and pre production.

Just for the record I think you will find this design to be VERY time
consuming. Granted we had to develop our design as we went but we still have
over 1800 hours in the prototype. Cedar should work very well for your
boat. We chose the Mahogany after several months of market research. It is
more durable but still the lightest of all the Mahoganies. I also have been
a professional craftsman for over twenty five years so I do have a little
bit of experiance in this realm. You will definitely need some helping
hands especially when you tackle the side planking maybe you could get you
wife involved in that respect and she might enjoy it!!

Good Luck! "May the barnacle gods be kind to your bottom"

Yea! and if we can figure out a way to crack the Hydrogen and Oxygen on
board we would have unlimited rage!!!

This technology will come to pass I think but it is still a ways off.
