You should be carefull when upgrading your shrouds and forestay. In the Mid 80's, hobie lengthed the forestay and shortened the shrouds, also they changed the front crossbar to rake the mast further back. I currently have an overration problem on my h16 because of this. I believe that the lengths are in a similer post on the forum.

Also, Midwest sailing has started making up new forestays and shrouds for the older boats.

To my knowledge, they do not include the lengths of the adjusters. You can add a second adjustment plate to the forestay and rake your mast back if you dont need to replace your lines. I believe that is what most of the racers do.
