    Wow, that would be the perfect boat for the inshore canals and lakes over here, nice!

    Sweet looking boat.
    I was born on a wooden boat that I built myself.

    I'd like to see a pic of the fellow walking past the boat inside that compact cabin.

    I'd guess sitting only - but maybe room for a stove & a couple of bunks. Love to see the interior - I like the boat!

    She has been my dream power boat since I first opened whichever volume she’s in in in the Woodenboat Plans Catalog.

    She looks lovely “ in the flesh”.

    The cabin is for camping and for keeping stuff out of the elements.

    Not much room for people in there...

    I can’t say that I see the point of it with half the length taken up by a cabin that is too small to be of any use other than to house the engine - she looks like a miniaturised version of something that’d actually be a useful size.

    Is there a plan view available? Are there bunks or something alongside the engine perhaps?

    Or is it purely intended as a work/tow boat perhaps?

    As its name implies, it is a utility launch - no bunks, no head, no table, just a warm, dry storage area for ropes & tackle & stuff.

    Any constructions details? Carvel...strip...glass in or out...framing? Engine choice?
    She looks lovely.

    I get that the name implies what it is designed for, but it “looks” to be built more like a picnic boat than a work boat and there are so many work boat designs being adopted for leisure craft use - quite often just because of some romantic notion, that I wonder at the choice of some of them for such a purpose..

    I do not have any info on the construction method used in this build, Paul. The ad for plans in WB says it is designed for carvel planking, and powered by a 6 to 8 hp diesel.

    If memory serves, the ad copy for the Zimmer launch in Fifty Wooden Boats (I think) states that she was originally built as as resort ferry. I will check when I have a chance.

    If so, then the observation that she is built like a picnic boat isn't all that far from the mark.

    From Fifty Wooden Boats:

    "Designed as a tender to a Canadian north-woods fishing camp, her principal task is to ferry passengers and supplies between the camp and town, some miles across a rather large lake. Great speed was not desired; what was wanted was an able hull, one that could cope with the chop from a fresh breeze or glide silently through the water to avoid disturbing the fishing grounds.

    ...the boat was designed to use the ... Sabb single-cylinder 6- to 8hp diesel. But it should be noted that her top speed (7 knots) is achieved at half-throttle ... providing plenty of torque to swing a large, efficient wheel. At that rate, fuel consumption is a little under four-tenths of a gallon per hour, which translated to about 18 mpg.

    The cuddy aft provides a safe place to stow gear and offers shelter against a passing rain squall or a chill breeze, while with the canvas hood indicated on the drawings and some camping equipment, she can even double as an overnight cruiser."

    Well, there you go. I must say I've always liked the look of this launch.

    Question: I notice that the boat in the OP appears to have a smaller diameter prop and more air between the prop and the rudder than the drawing seems to show; supposing that is so, how significant a change do these things make to the numbers quoted? I would suppose that efficiency is reduced, since the engine will have to turn at higher rpm, and that steering sensitivity would be reduced - is that likely correct?

    You’ve completely changed my opinion - I can indeed see the point with that description.

    I think this is a design that could be well suited to electric propulsion.

    I love it when what at first look like bad ideas are actually very and specifically good.

    I expect that the prop is smaller because the prop shop that supplied it did not read the passage from Fifty Wooden Boats that I posted above: "...it should be noted that her top speed (7 knots) is achieved at half-throttle ... providing plenty of torque to swing a large, efficient wheel." and sized the prop for the engine power and gearbox ratio. That will probably reduce her fuel efficiency, but it will prevent over-revving and possibly damaging the prop with cavitation (these youngsters today who believe that a throttle is actually a full-on/completely-off switch, eh? <grin>) I am not so certain about any adverse effect on steering - what is lost of a larger diameter prop-wash acting on the rudder may be gained back by a smaller but stronger prop wash from the smaller, higher-revving propeller.

    I do not know, Andrew. My world usually involves much larger engines, so I don't pay much attention.

    I used to own a scaled up version of that - scaled up to 33' on deck, built cold-molded in North Carolina, reportedly with Nelson Zimmer's input. I'll see if I can find pictures, but it was a long time ago. The owner previous to me added a small pilothouse forward of the cabin, as well as a mast/main/genoa.
    It had been sitting for a long time and needed a bunch of work. Sadly my job vanished when I was partway through so I sold it to a gent with more time/resources. I think that he still lives aboard on the Chesapeake.
    It was named "Kiss Me Kate" when I bought it, re-named to "Uncle Duke"...

    I had this thought as well. I am looking forward to a time when electric boat propulsion isn't astronomically expensive.

    Thanks very much for the reply.
