I have only done this 7 times and therefore, I am no way an expert or even an intermediate. I did learn a few tricks from this forum and other 21 users. The SC is way different to the SE and I do not know if there are many similarities to raising the mast on them. The SE does not have a gin pole, has curved cross bars which makes utilizing trapeze wires to prevent mast from swinging side to side and the mast is 4 feet longer (heavier). Here are my tips and suggestions;
I use the trailer winch hooked to the forestay underneath the furler.
I place a 6' extension ladder 4 paces behind the rear crossbar and rest the mast on this while attached at the ball. I also have already attached my mama bob to the top of the mast.
I have the wings in position and tied with the trapeze wires / bungees outside of the wings and the side stays inside of the wings.
Side stays in top or second adjuster hole.
Have one experienced crew at the trailer winch and one experienced crew (me) on the rear of the tramp and one inexperienced person (grunt) at the ladder. I have found with three people the raising of the SE mast is easy.
The person on the ladder raises the mast as far as they can until the winchman can winch. The winching is hard because of the low angle of pull and the higher the mast goes the easier the winching.
The person on the tramp ONLY keeps the mast from going left and right.
The wincher needs to winch as fast as possible, because the higher the mast goes the more stable the mast. If the mast starts to swing they need to make sure to not stop winching.
As someone suggested to me I need to build a quick bipole for the rear of the boat to raise the mast just enough to allow the winch start pulling the mast up and thus eliminating the thrid person on the ladder. The bipole needs to be maybe 6 feet above rear bar. Then one person to stabilize mast and the other to winch. I don't think I would do it with less than two people and preferrably three. I won't solo the boat anyways, so this should not be a problem.
Bringing down the mast is the reverse and the bridle wire pins removed from the furler is the only standing rigging I remove. The only other difference to lowering the mast is to winch slowly, as the mast comes down quickly. The person on the ladder needs to be prepared and once they touch the mast the winching can slow way down to not hurt the person on the ladder.
I wish you good luck as if the mast gets away you can get hurt someone or something......
