Howard:
Nice photos. Oar looks kinda like what I'm contemplating.

I thought the way Bob put those oarlocks on was pretty neat. Have
wondered how well it worked to row the boat. I've also heard of
guys fitting oar locks into the top of sheet winches, which are
about the right location, but that leaves the oar height somewhat
high.
On the Japanese sculling oar, I've built one of those too. First
attempt was a crude one to see how well it worked. Initial attempt
on the Spindrift was disappointing as it didn't want to rotate in
the oarlock, so I went back and modified it some. Didn't have a
chance to try it again and it's gotten pretty cold now for boating.
I think it might work, but so would the other one.

The Spindrift gets rowed or sailed. The oars on it do pretty well
and 1.5 to 2 knots is pretty easy to get. You can cover a lot of
ground doing 2 knots. This was just playing around on it. I view
the rowing option on the Montgomery as a third, emergency form of
propulsion. Something I know will work when there is no wind and
the motor won't start.

Rowing the M17: Check out the Strawanza photos at the following
link. Bob Eeg mounted oarlocks on the toe rail track and used 12-
foot break-down oars.

I'm playing around with the idea of a Japanese sculling oar
design, called a "Ro", ironically. It places the blade vertically
at rest rather than horizontally and may be more efficient.
The following web site discusses that design with video.

Hi Harry,
Welcome to the group.
You raise some interesting points for an off season discussion.
I have been pondering a post I read here (I think) recently about
the difficulty of using a single oar as an Oriental yuloh. I
believe the geometry is wrong for efficient use of oars with our
small boats. Our boats have a narrow beam, short cockpit and
high freeboard. If you place an oarlock on the top of the
coaming or transom, you have poor leverage for seated rowing or
use of a yuloh (yulohing?). Some people stand up, which
increases the angle of the blade in the water, and improves the
leverage situation by allowing use of a shorter oar. I would be
comfortable standing in calm water, but not in extreme conditions.
So…if I HAD to use an oar I would think about installing oar
ports. The ports would be located about waist high along the
sides if I wanted to row or in the transom for a yuloh. Bolger
has used oar ports as did the Dovekie. In extreme weather the
ports could also function as cockpit scuppers or be closed off if
necessary. Ports would also have the advantage of allowing the
use of shorter oars.
Or..I would consider using some sort of an arm that would locate
the oar lock several feet outboard. The leverage situation would
be improved, although longer oars would be needed. Modern racing
shells often have oar locks mounted outboard.
And..I would give a lot of thought to a sliding seat with a
pivoting brace for the feet.

Greetings from N. shore of L. Superior: -15F,snow& wind last
couple of
nights but at least my M15 is safely tucked away in its dome
shelter!
Bob Eeg's tale of the specially equipped M17 that he constructed
for the
Austrian man was fascinating and raised a couple of questions
about the
M15: (1) Has anyone tried rowing one, and if so how was it? and
(2) What
were the worst conditions a M15 has survived intact (wind, waves)
with
all sails down and only motor power? Pardon me if these questions
have
been asked before- I joined just last year. If they have please
point me
in the right direction and I'll check it out. Thanks and safe
sailing to
the lucky souls in the south. Harry Elmslie
