You will probably have to get one made or adapted to fit.
I had to buy one of those monopole fittings and screw it to mine.
No big deal, should be able to find a stainless fabricator locally to knock one up at vast cost.
Howells have Whitlock brackets, but having looked at the Lewmar/Whitlock site there was nothing that looked like the ped on a 311 (unless it is discontinued but all the other 311's I have seen have the same ped), that is how I got here. The bracket is quite simple it should be a case of just shortening a rod - I'll post the results.
The Bavaria bracket worked but I had to use two pieces od 2x1 Teak to off set the table bracket away from the compass housing - I would post the pictures but I can't figure out how to attach them.
Ade,
Did you figure out how to attach photos? I have same requirement for table on 311. It seems there are two possible solutions for the mounting mentioned in this thread (monopole and whitlock), and am not sure which works better in terms of space needed when folded and stablility. /forums/images/graemlins/confused.gif
