This "tunnel boat" is real interesting

Penn Yann had a very similar design only with a rounded chine rather
than a square chine. They worked well enough I guess, but it never
really caught on.

It's an interesting design, but I'm confused about the tunnel system.
Looking at the drawing, it would appear that the prop sits half way
out of the water.

Than can't be very efficient.


Have you ever tried close quarter maneuvering in a single screw, tunnel
drive Penn Yann?

It's no wonder it never caught on.

Well, *I* did a little close-quarter maneuvering in a Penn Yan when I
was about 14, and it resulted in a drive up the tunnel. I forgot whether
it was a single or double screw. I also forgot her name. Ahhh..age.
