No more diesel for this guy

Imagine living on board your DSe in the Islands - never running your diesel generator - the sun and wind providing ALL your energy - power for your refrigeration - power for your air conditioning - power for cooking - for your outboard - power to move your DSe from island to island. Just imagine....

Step aboard your new DSe from the after end - the steps are designed to allow boarding from any dock height from the lowest of floating docks to one six feet above the water level.

The dinghy stows neatly below the “Rumble Seat” on the bridge. The outboard is electric, charged from the DSe’s solar array. Wide side decks lead to the bow.

The port transom hatch opens into the guest berth - the starboard into the machinery and storage space. A dedicated hatch and davit makes it easy to off-load folding bikes (or the Boat Show Special Segway) either onto the dock or into the dink.

By distributing your weight using a 2” closed cell foam pad, you can access get on the solar array (very carefully) for maintenance or sunning.

Each helm chair has equal access to the helm. Similar to high-end sports car chairs, they hold you in place and are comfortable for hours on end. Each rotates, has fore-aft sliders and an adjustable reclining backrest and removable head rests.

Forward to port is the sliding plexi companionway hatch opening into the deck house. Rollups stow neatly out of the way when not in use. Snap on panels cover the sliding door openings.

The Deck House of the DSe borrows heavily on the proven layout of her older sister, the Island Pilot 435 - The same style furniture using lush fabrics, over-stuffed seating areas and lots of glass. The high-low dining table is suitable for feeding the entire crew or lowers to a stylish coffee table. The added space of the DSe allows us to add a full-length settee opposite the L-shaped one (which converts to an extra-long double berth for extra guests).

A pocket door separates the Deck House from the on-deck Master forward - plus, there’s an opening panel to starboard to open up the space during the day.

Is there really a market for such a boat?

Where's gludy when you need him? /forums/images/graemlins/blush.gif

Seriously, it might not be the solution, but at least its a step in the right direction. i think there probably is a market for this sort of thing, and while no doubt very small it will only grow.

I think boat manufacturers (mobo) are very slow in accepting change and evolving. At the moment all are looking to make more effieicent boats for sure, but only using variations on existing technology. IPS is ok, but its only really an outdrive for bigger boats in terms of efficiency.

The most exciting thing I have seen recent is Yellowfin, but even that relies on a diesel motor and while much better in terms of consumpiton than the current crop, is still woefulli innneffiecient when you really consider it.

Is it sexy? No. Could I buy one? no. Would I buy one if I have the time/money to use it? Actually, yes. I just might...
 
"Is there really a market for such a boat?"

Could be. Interesting design. It needs to be made a lot prettier - that sure is ugly. Also the solar pnels need to be cleanable and I'm not sure those were - you have to tread on them carefully and there were gaps between the panels to allow gunge to accumulate.

Main concern for me would be if it weren't sunny you might get say 3kw from the solar panels, plus 2 x 5kw diesels. So, 20hp. I wouldn't fancy passagemaking in waves with that. OK, you can have more power for a while using the batteries but only for a finite time before they need a charge. It's just not enough to be appealing.

Not if it looks like that /forums/images/graemlins/smile.gif

But, seriously, yes I believe there is as a diesel hybrid although obviously it doesn't have the advantage of regenerative braking as in a car. I'm not sure about the solar panels as they take up too much deck space

Mochi have recently done a similar thing with their Long Range 23
 
......yes as a retirement/live aboard craft. However we already have those, sailing cats! Of course you would use even less diesel on this girl and have more toys due to batteries. I think this is the beginning. A bit more development on the efficiency of solar panels, the efficiency (and weight) of batteries and a bit of aesthetics and you have a credible live aboard.

As a convert to Catamarans this is a sensible move. The main problems with Cats is that you need to dock for water and a bit of power every now again (and provisions). If an efficient watermaker could be developed which would use excess power in the day once all batteries are topped up then it would be even more credible!

Gets my vote...if not my cash yet. The only issue in say the med, is finding a cheap winter mooring. The cost of running a solar cat would be lost with double mooring over the winter!

Rather than the 'offshore' market, might it be better targetted at the inland waterways market?
Perhaps not enough sunshine on the Norfolk Broads but S of France Canals and there's vast numbers pootling about on the Itercoastal Waterway in the USA. It might need to be lowered for bridge clearances, but the base technology should be sound for that environment.
 
Fair point, but on Inland waterways there are bridge clearance issues and there is the risk of damage to the panels from kids throwing things. Better to base itself in a river canal near the Med...

[/ QUOTE ]Now that is ridiculous.
How serious is it to advertise a boat as capable of a range measured in thousands miles, when her deck can fall into pieces just by walking on it?
Any serious green water can produce a pressure even higher than that, thus possibly blowing apart all of the panels in just one hit.
Besides, I would be very skeptical also about the resistance of those very wide windows, by the look of them.

On the other hand, as an island hopper in fair weather and as a liveaboard (rather than a bluewater boat), she does have a point.
And I'd expect her bigger sister (60'x25'), whose drawings are shown in the brochure, to be even more interesting.
I just wonder why they didn't (at least, judging by the drawings) build some keels under the hulls, to make the boat capable to sit on her own bottom.

Just a couple of other comments:

@Deleted User: I can't see ANY similarity with the Mochi LRC23, aside from the fact that also Mochi is marketing her as a "green" boat.

@jfm: where did you see the 2x5kw diesels? According to the specs (unless I got it wrong), she seems to have 2x75hp, which wouldn't be too shabby also in serious waves, for a catamaran of that size (aside from the above mentioned concerns).
 
Mario, the LRC23 is a diesel hybrid boat and, although it's much bigger and more expensive than this one, the concept is similar in that the target is zero emissions boating for at least some of the time. It demonstrates that a few builders are beginning to think beyond the traditional planing hull + 2 big f***-off diesels design
 
Well, I already posted some thoughts on the Mochi in this thread.
In a nutshell, I wouldn't even call that a hybrid propulsion - a double propulsion would be more akin to reality imho. Not to mention that in the case of Mochi "zero emissions" is just a marketing concept - much more appealing than "delayed emissions" I guess...! /forums/images/graemlins/smile.gif
But aside from semantic yes, some builders are beginning to think outside the box, and that is indeed positive.
I'm very curious to hear about the Mochi hull for instance - aside from the propulsion.
On the other hand, the approach behind this DSe thing is much more radical, particularly in exploiting the combination of a real hybrid propulsion with renewable energy.
That's why I told (maybe being a tad radical myself...) that I don't see any similarity.
