17 foot mahogany barrelback runabout just finished
Hi all,
We just completed a brand new, not restored, 17 foot African mahogany barrelback runabout. The really cool thing about this boat is that is has twin 85 peak HP ELECTRIC MOTORS, Yes I said electric. So far we have had her up over 30 MPH!. I had to start from scratch as we could find no plans available anywhere. I found some hull design software and we took some offsets from a 1/8 scale model and modified the hull from there to accommodate the twin screws and additional weight of the batteries. We are carrying a 15000 watt battery pack of 100 amp hour deep cycle AGM batteries which will give us all day cruising at hull speed with some reserve to show off when desired. Check out our web site www.edison-marine.com There are some streaming videos on the site. Tom in Oregon |

Tom in Oregon Whats the 'on plane' run time? 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. |

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 "Delburt D" wrote in message news:hV33j.19988$ht1.12317@trndny01...

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.

Spam. Sam for a nice looking boat, but still spam. Plus, for 100,000 to 160,000 USD I can get the real thing, not some lame 21st century imitation.

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. |

Mike Worrall Los Angeles 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. Tom |

Sorry you feel that way,
While I do want to sell boats, I don't really think this is going to get me any leads. Just for the record I have made this post for informational reference. We have a great discussion going on rec.boats. We Have tried to build a boat in the spirit of the past but with newer technology which reduces maintenance and is designed for the application. Beside how would you feel if we took a vintage boat and modified it!! I feel that would be sacrilege. I am open to all questions regarding the construction methods and drive system. I am here to share not sell. Tom wrote in message ... Spam. Sam for a nice looking boat, but still spam.

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!

My contracting company website was broker for several months during construction but I have over 450 pictures of the construction from the strongback to completion. Until then I am happy to field any questions. The drive train is simply a direct coupling of the motor shaft to the prop shat using standard marine couplings and shaft logs. We are looking a a v-drive reduction gear to get our motor speed up and increase usable torque at the prop so we can use a prop with greater pitch. Right now we are spinning a pair of 13x 12 counter rotating wheels. I will work on the construction pictures as time is available. |
