Hi All

Approximately 30ft or 9.15 metres, BUT depends on your actual draught/displacement or mast mods etc this is based on the original Holt mast set up.
If I were you I would allow at least 0.3m or 1ft safety clearance

It is common sense both for draught and mast height to use a "pilot's foot" clearance. The mast should be approximately 25 ft or very slightly more, roof height above sheer 1.5 ft, sheer 2.5 ft so I think 30 ft should be enough except for top mast light, VHF aerial and wind indicator.

A good place to test the theory is Rochester bridge, you have to find the right slot when both water and height clearance is in the range...

I measured Redbug's mast over winter and it was 8.1m excluding windex etc, so that tallies with the comments above.
