Re: [macgregor19sailboats] fin on rudder +Doug Pile invitation
- I motor with the rudders down but did not notice anything weird. The water
just sprays to the sides. I don't know that it makes any difference if your
raise them - mine at least are still mostly in the water when raised. They
just stick out further from the boat and push back on the tiller much
harder, making tiller movement harder.
Thanks for alerting Dougpile. You do a lot of work for this list.

Subject: [macgregor19sailboats] fin on rudder +Doug Pile invitation
I was just looking at an article on the Corsair 24 folding Trimaran
which showed a detailed photo of their rudder. About halfway up
the rudder, they have a teardrop shaped plane perpendicular to
the rudder and extending out an inch or so from the rudder to
prevent water from riding up the rudder at higher speeds.
They claim that it improves control and performance much like
similar devices on airplane wings. Since they can sail at
speeds approaching 20mph it's more of a problem, with them,
but I was wondering if anyone who motors with the rudders
down has ever noticed water rising up the rudder at high speed?
I'm still hoping someone else designs a linkage between motor
and rudders but if I don't see one soon, I guess it will be a winter
project for me.
I just realized that we aren't included on the excellent Mac 19 site
maintained by Doug Pile,
which also has some of his beautiful photos, and he's not a
member of our group so I invited him to join.
Hope you're all enjoying the summer. I'm planning to spend 3
weeks in Alaska looking for Mac 19s and whales, etc. Mike
