Amen to that! I grew up on boats with larger diesel
engines, operated several, owned several, all had raw
water pumps that required rubber impellers, replaced
them every 100 hrs, even if they didn't look bad. As
we know the rubber breaks down overtime, plus it
conforms to its surroundings, hence if it spins in one
direction all the time it will fold, bend, etc
opposite of the force, which creates a negative seal
between the impeller and the housing, resulting in
less suction. Which as an end result leads to burnt
out bearings in the pump, or in a worse case scenario,
an overheated cracked up engine. About time someone
came up with something better.

I'm a big fan of your writing. I'm also grateful to you for actually
building one of these tunnel stern boats and writing about the
I have not yet built one, but I plan to. (Just finished a Bolger
Light Schooner and the wife says I have to wait a few years before
building another!) To that end I have a couple questions for you.
First, would you mind providing a list of the mechanical parts that
went into Rescue Minor with sources and approximate costs? Inboard
power, particularly at 20hp, is a new to many of us in Outboard
Wonder Land (Wisconsin). I'd particularly love to know what reverse
gear you're using, source, cost, etc.
Now on to the hull. I'm trying to decide between Rescue Minor and
What's your take on the different chine sections? To me, the Rescue
Minor looks like the better sea boat, since Shoals Runner has a point
where the chine reverses, forming a straight-up flat-bottomed skiff
for that little bit. My light schooner has that hull form and gets
the hell beaten out of it by powerboat wakes. But maybe it doesn't
matter when it's such a small area?
I'd love to hear your thoughts on that. To put this in context, I'm
thinking about the steep chop of the great lakes and these wide,
shallow puddles we have all over up here. I guess that Normandy stern
might help there.
I'm somewhat inclined toward Shoals Runner, all other things being
equal, since it seems nobody's built one. It'd be nice to see how it
But total weight counts. I don't really want to mess with trailer
brakes, so I think that limits me to 3750# for boat and trailer in
Wisconsin. Might be 2000#.
I'm pretty sure your Rescue Minor weighs pretty close to Atkin's.
Anybody got a guess on the hull weights on these two designs?
If you read Duckworks you probably know I'll be writing about the
results of whatever I build. I just can't shut up, I guess.
Many thanks in advance, folks.
