Anyone wanna buy a boat company?!

For only $300k you too can own your very own boat company!!! LMAO!

Who among us is gonna step up and buy it?! The hull design was actually pretty cool but I also wish they had a pilothouse or cabin style above deck. This design is only good for FL, Caribbean etc. Cool boat but obviously it didn't sell and now the company is for sale for peanuts.

How do you make a small fortune in the boat business?
Start with a big fortune!

We have a friend who owns a marina in Massachusetts. He regularly says, “Do you know how make a million dollars? Buy a marina for 2 million”.

The map makes it look like it is Jarrett Bay just north of Beaufort, NC. Interesting. I have never heard of them or recall seeing them at boat shows. $300k, huh? not bad if you can find the right people.

**EDIT** Oh... now I know why... They are UGLY :-) http://www.blueplanetcatamarans.com/

Hmmm, boat is innovative. 2 heads? Forget to put the lid down you will not be welcome in bed without a hot soapy shower.
I suspect this is real 'hands on company' in other words, you pay your employees and you work for free.
Hey, at least the guy tried, for that, I give him credit.

Too bad it has such small windows! I understand small windows for offshore boats but I don't see this design as an offshore boat.

When we were on the farm we used to say if we won a million dollars we would probably keep farming until it was all gone. I guess they kept making boats until all theirs was gone.

Interesting concept. I don't think it's practical without another means of propulsion. The electric drive setup looks pretty small so it probably wouldn't take much power to move the boat. It would be interesting to see what a diesel electric setup could do for efficiency.

Others have tried and failed. From what I understand, there is too much loss converting diesel to electricity, and driving electric motors to push props. With all the losses in props, apparently you're better off with a direct drive system where the engine runs a tranny and that drives the prop.

On a cat, it seems like having one or two generators supplying house power, charging batteries and pushing the boat along at a decent clip, it seems like it would be better to have one engine pushing both electrically driven props rather than having a yanmar in each hull. But again, I must be missing something...

It's common in large boat/ships. I know there will be some efficiency lose in the generator but I don't know what it would work out to compared to conventional setup. It would be interesting to see what could be accomplished with a dual gen setup like you described. Run one gen for slow speed and greater range and still have the control on both drives or run both gen for greater speed. Iirc a 10kw Diesel gen will burn just over 1 gph at full load. So if you could achieve 12kn you could get aprx. 6nm mpg. Anywho. Just thinking out loud.

Put the diesel in RIB and tow it behind you.

Thats some good "thinking out loud" I can use that info. I have an 8K Westerbeke generator and am thinking about putting a 4 K electric motor clutched to the main prop shaft for emergency propulsion if the Volvo ever fails.

If I can get 2 knots and do it with diesel its better than a gasoline outboard for "take me home" and will be in full control, on entering my slip, from the helm. If I can get 0.5 gallons per hour I will have a range of 400 hours.....if the generator could hold up to that at half load.

Thanks.

Half load for extended periods of time is no problem. The electric clutch/motor idea is definitely interesting. The only thing you may want to think about would be a way to control speed of the motor when you engaged it. when you do an across the line motor start. The amps is something like 8x rated amps. It also is hell on gens to start if not properly sized.

Lol that would work but it seems like a lot of extra work. Although I would be curious to see what it would run with two 200 hp ox diesel's on the back.

Would that starting current be that high if the electric motor was not loaded (clutch open)? I would have the option of either a DC motor or an AC motor since the gen set puts out both. One or the other might be easier to speed control. I built a "chopper" control for a DC motor back in the 70s when I built a hybrid car. Dont know about AC speed control.

Years ago there used to be something called a 'cruise generator'. It was installed on the main shaft. I guess if you rewired it, it just might run as a motor. SHRUG

The load would be minimal with the clutch open but as soon as you engaged it the amps would spike not to mention it would be the marine equivalent to dumping the clutch on a street car. The best option would probably be a vfd. You would be able to use a bias signal to control the speed. So you can engage the clutch then use basically a throttle lever to bring up the speed. Only down side would be trying to reverse the direction without a lot of complicated wiring/controls. DC is pretty easy to change direction with just a couple of contactors. Down side is high amps compared to the ac motor plus having to figure out a way to control the voltage/speed. One possible way would be to setup the gen with rectifiers to make DC and use the voltage regulator to vary the output voltage. Most avr have a on board voltage pot at the very least. Some may have an option for an external pot. Or worst case swap it for one that does.
