T-Pain Is On A Boat: Re: [Electric Boats] pulling the plug...

Hi Josh,

would you care to name the builders as i would also be interested at those prices. Thanks

Those costs are high. I have received quotes for my 40ft power catamaran from builders in both Turkey and China that were both under $300k for a fully completed boat.

Hi

Good points james - I would also like to add that there are not too many new 40ft boats of any kind on the market these days for under 400k. I work at the moment in a boat building company in China and we just priced a 40ft RIB with very little superstructure and the build costs alone were at minimum of 300K. Any vessel in this range of size will be spending around 100K for engines package as a guide price plus plus plus so the price comes up rather quickly.
I also priced a catamaran hull of 40ft to be built in South America to awlgrip finish bare hull and that alone was 100K with no interior no hardware and no engines etc etc.
lets all remember the price of resins and cloth has increased in the recent years!!

So as you say to be pre buying your milage ahead of the game has a huge advantage - and its all dependant on usage. Im also assuming (anyone please correct me if im wrong) that ongoing maintenance and oil changes etc etc will be more costly thatnsolar hybrid maint ?

PS Just for reference - our yard here uses 90% hardware and machinery from other counties so our pricing structure is only cheaper on labour and basic consumables etc.

Thanks Mark

Two problems with your assumptions below. First is that a lot of the price difference in the DSE between similar catamarans is in that they use Steyr engines which are not cheap even before you add in the electric option. So you would first need to price one of the normal cats with Steyr diesels to even get a base line for comparison. And account for any other difference in fit and finish.

And the second and more important mis-assumption is that this boat is being purchased with solar cells included. So you are pre-purchessing a large amount of fuel ahead of time, so to make any _honest_ comparison of the price of a boat that includes maybe half or more of all the fuel it will ever use in the purchase price. Is the price of another catamaran and half or more of all the fuel it will ever use! Which would be very dependent on who owns the boat and how they use it. To even get a guess on how good or bad a deal it would be.

Lets take this to the extremes in both directions:

If the owner of a DSE use it as a live aboard and to circumnavigate the globe at low speeds then he would love the price of his boat and would save thousands and thousands of dolors in fuel cost over the 40 year life of the boat. So for this person the price would be cheap even before factoring in what diesel might cost 40 years from now.

If the owner only boat once a month and at very high speed, he will never recoup the cost of the solar cells and will have wasted a lots of good money.

Hopefully we can all agree that buying any two boats is a little more complex of a decision then unit price to interchangeable widget. Comparing the price of two different kaiaks can be extreme. Drive down to your local boat shop. One kaiak cost $400, and the other Kaiak cost over $1000. They are made of different materials and to different standards. And the cost of any two 40 foot catamarans very just as much if not more.

So to reiterate I don't know if the markup is 200,000 or just 50,000 compared to a "similar" boat and knowing that markup would be important. Knowing the future cost of diesel would also be important to gauge whether this boat is a good or bad deal. Neither would be easy to guess.

But saying all that. Yeah I think the boat is a little over priced. But I don't think that has anything to do with it being a hybrid. ;-)

Hi James,

Do you have any prices to compare with regular boats in this size range? The one that did list a price, the DSE at $500,000US seems kind of pricy. I think that you could buy a new diesel powered 40' yacht that was much better looking and have almost $200,000 left over for future fuel purchases....

The boat was a hybrid, with a 60hp diesel, a 48V AGNI 95 (9kW) electric motor, 1/2 ton of batteries and plenty of solar panels. They ran at 3 knots under electric and any important pasages were run under diesel at up to 5.5kts. They averaged about 17 miles a day.

In a weekend he'll log close to 100nm of coastal/offshore distance at speeds around 10kts (that's the relaxed part, most of his peers cruise at 16-18kts). Electric drive, hybrid or not, has little value to him.

The Dragonfly went this route. Alternatively, one could build install an electric drive that can operate the vessel safely by itself then add the considerable onboard power generation to run the boat for extended periods (more than 30 minutes). Both scenarios are heavy, complicated and expensive when compared to a regular driveline. There are few (if any) efficiency gains at this scale and both types of drives will be running a diesel for most of their operation, keeping them fairly dependent on fossil fuels and diminishing the electric drive advantages (clean, quiet, low maintenance, etc.)
