I found this interesting Ad for a Seagull rudder?? The Ad came out of a 1968 boating mag, really, what is the point and from the amount I have seen about, not that popular, glad I didn't buy any shares in the company
The whole point is about the lack of steering when you kill the thrust. This is also a problem with the little hondas with the centrifugal clutch. Some people use a rudder!
There have been several attempts at this, none stayed the course.
I have just launched a 14ft runabout (Sea Nymph hull design) and after considerable help and input from sources including here - am incredibly pleased and impressed with the way my silver century pushes it along. We actually had a wake!! and I would approximate our speed at around 6+ knots ? The seagull was to be a temporary option but I can see it becoming more permanent. Fantastic and economical for how we want to use the boat.
Anyway, my point is that the remote steering ( rope / Pulley ) is original , works fine , but "wanders" a bit, and requires constant correction. I am assuming this is the result of pushing a hull primarily designed for planing at a low speed. It feels like the front " V " is acting a bit like a rudder. Not a big deal , easy to live with - but as per this thread I had thought of rigging something up to make the steering more precise. Anyone encountered the same issue ?
I googled 'sea nymph' and can see the steering mechanism a little better. Fine on land but on the water the rudder vane would definitely be an advantage.
