What Kind??
I have owned a MacGregor Venture 15. I am not sure they made a 16. For the MAC 15, the standing rigging was as follows: There is an inverted V cable which runs from the front of one of the pontoons and then diagonally up to a forestay or cable and then back down to the front of the other pontoon. The forestay then runs up to the front of the mast about two thirds of the way up. There are two side shrouds which also run from that same mounting point on the front of the mast and down to points on the pontoons just aft of the mast. As a matter of interest, I found that it was easier to raise the mast by having only one of the side shrouds that goes just aft of the mast disconnected. I then pushed the mast up and against the other shroud and forestay. I was able to rock the mast in order to get enough play to get the pins into place. If this is impossible to understand, let me know and I will try to come up with a picture or possibly a sketch.
