Re: [epibase] what would you do
Don't be a pussy. Get her on a close reach so the mainsail is out of the way, Exit from the masthead and freefall off the downwind/crosswind side. 150'? at sea level? into water? no sweat. but have a good pilot to come around and pick you up.
Even without a rig, being at the top of the mast while sailing is one of the coolest things I have ever done. The accelerations are INSANE. Moment arm is an amazing thing.
