I suggest you look at the catalogs on the Hobie site, Murray's, and also here. ( www.hobiecat.com, www.murrays.com, )http://store.catsailor.com) and look at the pictures they have of the setups. As for the shock cords, I think 6 or 8mm should be okay. (1/4" or 3/8".) If they specify another size you can just type in Google
0.25 inches to mm
and then it'll come back with
.25 in = 6.35 millimeters



Warm regards, Jim
