Re: [bolger] 40 Foot Diesel Launch isometrics

This is a cool one. I have two thoughts about this :

1) This is close to what you would by scaling up a box keel Sneakeasy.
An exercise that has ling piqued my curiosity.

2) You could do diesel-electric. This would probably be costly, but it
would give you low VCG and horizontal shaft axis.

Mercury tried something like that with their outboards, once upon a time. It was a short-lived experiment. The fact that it got tried at all is some measure of Kiekhaefer's iron fist as a manager.

There is an old wooden boat in town (Sultana) that used to tow the 32
footers out in Bristol Bay. Has the original Atlas which is direct drive
and turns at 325 RPM. Reverse is accomplished by stopping at Top Dead
Center and starting in reverse. Docking must indeed be an adventure and
I would not want to be at her "target" dock with say a modern Hunter or
such as she came in.

Good question, I don't know the answer. I do know that these old
Lister low RPM diesels have a long and stellar reputation for powering
boats, so there must be some solution. In my incomplete imagination,
I am thinking along the lines of using a belt drive, like they use
with the Listeroid generators. I imagine you could rig up a idler
pully on a lever to flip between forward and reverse, but some
inventing would be needed.

Looking on Google, I see this website that is selling a Lister with a
"marine gearbox" complete with photo (half way down page).

As always, very evocative work. I've often thought about those Listeroids for a boat (including this boat) for the same reasons, but have always wondered how you go about transmitting power to the prop with these single-speed engines. Do you just install an F-N-R gear box, slam it into gear and take off at full speed? Must make coming alongside a dock interesting.

You have convinced me. This plywood 40 footer, has most of her
displacement on a 3 ft beam. That long narrow box keel could be
insulated to be a long narrow ice chest. Outfitted with a low RPM
Lister-clone diesel engine the fuel efficiency would be spectacular.
(You could run on recycled french fry oil.)

Hmmmm, yeah. Could buy much diesel for 5k$ (need $$ to make the Listeroid work)

One could probably buy a more powerful tractor and scavenge it for the engine for what the Lister costs.

Don
Found myself thinking the ultra-simple Buehler design fills the same mission as I read HJ's post about hand trollers. And although it would not be has handsome as the Bolger design, the Buehler Pilgrim 44 would come together faster and, I would guess, cheaper.

I think the subject design may have been designed around an air cooled Deutz diesel. I'm guessing that is the reason for the large diameter stack, conveying cooling air and exhaust gasses from the engine up and away.

Either design might benefit from cladding with foam and glass as PB&F are suggesting for the AS-xx series as passagemakers. The cladding both for comfort and safety.

I see either as a fine and inexpensive live-aboard. I'd thought only of the outboard version of the Pilgrim as a live-aboard, because of the space saving, and the ability to isolate the engine from the living space. The 40'DL's box keel would be a great place for fuel, batteries, and wastewater tanks.

The Advanced fisherman uses way to much fuel for a hand trolling
operation. Distances are huge and efficiency is everything. I would be
very surprised if the 40' launch couldn't get 7.5-8 kts at 3/4 gal an
hour. Think the 40' could carry a ton of Ice?. 40' gives you a lot of
displacement even with only 8' beam. I have also considered Buehler's
Pilgrim 44 as a hand troller.

39'4" x 8 ft

It probably could be a hand troller, though for the same effort you
could have one of the new Advanced Fisherman, and have more
displacement capacity to carry ice.

Yet, the economy of the low RPM inboard diesel luggers ($2K) versus
the Honda four strokes OB's ($8k?) is appealing.
First time I have seen this one, what are the dimensions. Seems to me it
could be modified to be a hand troller for AK here if you keep the
weight aloft down.

I had not much thought of this boat, but looking closely it is really
great. Made of meranti plywood, with a thick sole. Powered by one of
those low RPM diesel luggers, (I would use a Listeroid), and with a
very long and streamline box keel, it would chug along with
spectacular efficiency. Decked out with tons of sprawling space so
it could accommodate a very large party of friends.
