A rudder port is a rudder port. It doesn't have another name.
Like I said, I am looking forward to working with him in the future.
All I can say is, and this is not a beat up Ken Loh by Stretch report, I emailed him last year for a part. Two months later i get an email from him responding to that email. I had already bought that part from another source and quite frankly, forgot I sent him the email.
The second request I sent was for a rudder port. I actually sent that email to gbparts and they forwarded it to Ken.That was 2/22/09. He is always nice in his emails.
I bought the rudder port from Buck Algonquin and if you are interested, go on page 89 in their online catalog and you can see it. It is the one with the 1.50" shaft. When I haul out I will post pictures in the appropriate place.
