I'm no technical expert, but I have been using what I am told is a
yuloh to power my boat for the last 10 years.

When I first stared I did some investigation and these are some of my

The yuloh is mainly oriental and has the blade of the oar horizontal
when at rest, The power strokes follow a pattern called 'falling
leaf' where the leading edge changes with each stroke. The tether and
fixed pivot are not a requirement but, depending on the set-up, can
make things easier.

The sculling oar is more occidental and has the blade vertical in the
water at rest. The stroke is called 'slalom' where the same (lower)  
edge of the blade always leads. This geometry has the added advantage
that the blade can also double as a rudder when gliding. It has the
disadvantage that it cannot be easily mounted on a pin so you have to
put up with the friction of a crutch or notch in the transom.

Neither system has a reverse gear or brake so make sure your bow is

Quite right, but a nice curve can make stowage round the gunwale much

I decided early on that the terminology could just get in the way and
will usually describe my activity as rowing or sculling, almost never
as yulohing.

Sail when you can, row when you must, motor
when you have to be at work in the morning.
