Netherlands electric wooden boat

[peterAustralia]

hi

I saw this for the first time today. Finish is pretty good. The boat looks fantastic. Is a low power hullform, max speed 10.5 knots. Carries 8 passengers. The way of the future?

I tried to embed the picture (is done in attachments) said that it exceeded my limit by 13kB, I have never posted a pic before.. do I need permission or something? Or do I hotlink it?

Right-click on the original picture. Highlight the address (url) and right-click, copy. Then in the forum, click on the picture postcard tool (insert image). An address window will open. Right-click, paste the url. Then OK.

Copy/paste the pic from any other website.

I'll have to revise my tag line. That side elevation is UGLY.:eek:

Here's an interesting detail - the windshield pivots up and down like a visor.

Very unique, and quite interesting. From a design standpoint, the visors seem like an unresolved detail. The hull is gorgeous.

It kind of "grows on ya". When I first saw the photos I wasn't too sure I liked it but after studying it more I think it's quite beautiful. But it does seem in need of a mast and sail IMO.

The lit. says it's a composite hull. What do you suppose that might be? In the one photo above it kind of looks like it might be a wood strip/glass variation. But then looking again...maybe not.

Very cool...

Very swoopy aesthetics but where does he hide all the batteries and how many of them does it take to go 10 kn.? And how far or how long can it go at 10 kn and a full load of passengers?

It says it has a 60 mile range, but doesn't specify at what speed or capacity that range is acheived.

Looks like it's cedar stripped. Good sequence of build pics at the link above.

Would be fun on the canals of Amsterdam

Turn that reverse transom right again, and give here a easely brailed traditional rig that could save power when the wind is from behind.

The bow is simply delicious :)

What do you figure she'd do in a chop?

That's quite an innovative design.

[mcdenny]

Really cool electric boat. The trimaran design is great for high stability and low drag. Really complex construction, though. No price listed but it's got to be $150k (+++?)

As is typical of many electric boat builders, they do not list range at speed. Too bad as that is the real measure of efficiency. It is easy to make an electric boat go fast or far, but not both.

Boom like a pair of kettledrums. But I reckon she's not intended for choppy water, but rather canals and the like.

[Chris Ostlind]

My Take...

While this is a very nicely executed (with exceptions) design for the intended purpose, the primary design has been kicked around in one form, or another, for many years now.

There is nothing wrong with the process of nabbing inspiration from the works of another. It would be good to attribute that Australian, Rick Willoughby, has been working on a steady stream of prototypes under pedal power for many years now... all pushing towards a resolved coastal cruiser for low power applications that is very much like this boat.

Additionally... and while I get that this is a Tip-O-The-Cap towards the enigmatic classic launch period with the upright windscreen and all; The drag created by the windscreen is not at all conducive to efficient use of the available power. Personally, I'd have much rather seen a windscreen with a suitable aft angle to enhance the flow of air over and around the boat while underway. There are plenty of examples from the same period in time in which the screens are aft angled with both a design and functional consideration as an integrated component.

Other than that bit of business, I just love the lines and functional potential of this boat and feel that this type of design study is long overdue.

Congratulations to the folks involved and I hope to see more of this genre in the near future.

It looks like there is a rear window which raises/lowers similarly - when the two windows are up it appears as though the windows and the top would form a single shell - it actually looks like a very nifty set of solutions resulting in an interesting and well executed design (setting aside aerodynamics). The only bit that looks out of place, to me, is the mast - the rake isn't echoed in any other line (not even the flag pendant has a similar line), everything about it looks 'add on'ish as opposed to integrated design

I like it. It's taken a while, but multihulls are getting adopted by the powerboat crowd, and a good thing. They should use a lot less power than planing hulls with too much weight aboard, which seems to still be the standard cruising powerboat.

Now, if the designers were to rake both the windscreen and the mast to echo the pendant mount, there'd be nothing about which to complain and that dude would absolutely rock aesthetically.

Nice thing... the flipping top could still work with but a simple adjustment to the pivot location.

Put one of these modified versions on the water in San Francisco Bay/Newport Beach Harbor and you'd immediately sell two dozen of them as water taxis/ pleasure cruisers.

Really guys you owe it to yourselves to go through the build sequence of photos on the website. It is strip built cedar on ply frames. The ply frames are cut on a CNC and I think if they sold those frames as a precut kit with instructions like Arch Davis does they could sell a bunch of these to the private boatbuilders like us. Very straighforward construction. Hardest part would be cutting the frames correctly but with CNC technology being what it is if they sold the plans with the CNC data formated on a disc that would make it easy to do.

Just click on the very tiny > in the bottom right corner to see the next photo.
I like this one. The young designer looking toward the future and the old craftsman who can make it a reality. They both deserve a well done.

They title this photo Two months work.

Doesn't this just scream KIT BOAT to you? It does to me! A very easily build design.

And it uses a motor that looks not much different in style than a Minkota trolling motor. Although I am sure it is much better engineered and designed for such a large load and all that, but still it is just a motor on a shaft that pivots. No rudder needed.
