OK its set up like I expected... It is not 2:1, you have no mechanical advantage on the halyard. All it does is eliminate the separate tack line and combine it with the halyard. Some Tigers have the same thing only it is done at the tack end instead of the halyard end. The reason you have more line to pull is because the same line acts as the tack line and the halyard, so you have that much to pull instead of pulling two different lines. Theoretically it should be faster than two separate lines... More friction though...
