Angus,
Arthur C Robb eh? I trust you will acknowledge his place of origin?
Very sorry for being off topic (again) - but only very briefly.

Was he a New Zealander? That I did not know. A highly talented and very underrated practitioner of the art.
This is an experimental Footy twin keel setup from about three years ago.
Don`t be concerned with the large carbon tube, that is not involved in this part of the discussion.
The bulb was slung on a stainless wire about 6 inches or 150 mm below the waterline.
It did not work.
There was not enough area on the fins to prevent excessive leeway.
The idea was scrapped and we moved on. :scared: As you do.
nice hull Ian, although a bit skinny for my taste.
If I undersood correctly you had two fins, and a separate bulb hung on steel wire.
Yes, correct on the bulb.
You are right on with your observation of skinneyness.
There is not enough buoyancy in this hull for an r/c Footy.
It was set up as a vane steered unit to try out the twin keel concept.:witch:
Maybe you could try compensating for small fin area by increasing the rudder area. I will post some pictures to ilustrate the idea as soon as I scan them.
