I have been confused ever since I read the post on cleating the main sheet. I feel like I need one more hand. I have raced with skippers who I know have no problems tugging on a line with two hands to bring it in quickly and powerfully when trapped out, but I never noticed how they do it.

I’ve tried:

Putting the tiller in-between my arm and side (I have found this challenging when traped way forward)
Passing each pull to my tiller hand (I find it hard to steer a strait course with this method)
I like the hand wrap method, but after reading the warnings of the dislocated shoulder I am not sure that is for me (though if I was really far out I would rather dislocate a shoulder than have my boat sail off without me).

They all work ok, but I need practice. What is the best way to pull in a line when trapped out? I would really like to not have to head up in gusts and be able to sail upwind uncleated puffy conditions.

The other problem I have is when tacking. Again, I feel like I have one too little arms getting out onto the trapeze.

When I tack I:
Let the main out a foot,
Come in off the trapeze,
Feed the jib around to keep the telltales streaming,
Pass to tiller around,
Cleat the jib,
Now here is the gross part: I hook into the trapeze with one hand,
Hold the tiller with the other,
And put the main sheet in my mouth as I kick out (which is pretty gross if you have ever been in lake Ontario),
But I really feel I need that hand to get out on the trapeze.
Then I pull in the main (hopefully using the technique you suggested)

How do you deal with our lack of arms??
