Re: Going up the mast on a trailerable sailboat?

Here is basically your calculation and reason why you should likely drop the mast as opposed to going aloft. They are based on previous statements by others.

Basically calculate the weight times the distance it is from the fulcrum. In this case 900lbs X's 3 feet which equals 2700 foot pounds. Now multiply your weight of 165 X's the height of the mast which was stated to be 22' and you get 3630 foot pounds. As you see, the moment above the water line is greater than the moment below the water line. Gravity dictates that the two will, for lack of better words try to change places. I hope this is helpful.
