Just curious, but what boat do you have?
A Jeanneau 54DS. Built before they switched to the fake teak and plastic seacocks on the 53s and 57s!
The cockpit is actually two levels. The rear level is where the aft most end of the boom extends. I'm 6'1" and the boom is well over my head, I estimated the 8ft. The fore of the cockpit is a bit higher, but the dodger covers it entirely and removes access to the entire mid-section of the boom. Still, it is 6+ ft above that deck. About a third of the boom is easily reached at the end by the mast.
When we drop the furled main for maintenance or winter, it is a royal PIA. (The Genoa is worse) Only my wife and I crew the boat, no way one person would drop and flake a traditional main. I suppose with lazy jack, etc, it would be possible. Just hope nothing requires you to reach it and fix it.
So far, zero hang ups with either furler (knock on wood) and, as you read, she loves to sail.
