Swan 40 Air draft

I have Swan 40 number 9 (1971) that has a tall rig installed.  Could someone tell me the number of feet from water level to the top of the mast for bridge clearance purposes.

Thanks,

Alan

The Swan 40 tall rig has an I-measurement of 51.0 ft, and then air draft is 55.3 ft without antennas.

Kind regards

Dear Professor,

I have had correspondence with S&S and apparently they do not have a record of a tall rig for this design (1971 Swan 40, #9).  Could you tell me if the tall rig, as designed, was a double spreader or single spreader rig?  My boat is double spreader.  I was wondering where on the mast to attach the baby stay.  There is currently no fitting on the mast, but the original fitting on the deck is still there.  Also, I was wondering if the dimensions for the storm trysail would be the same for both rigs?  Lastly, do you know where I might get the sail plan for the tall rig given that S&S doesn’t have a record of it?

Thank you very much,

Alan
