Might have overlooked it, but there doesn't seem to be any specific restriction on using line (i.e. dyneema, vectran, etc.) for the forestay of an H16. Given that it's only purpose is to support the mast when un-rigged (or when jib luff wire unexpectedly breaks), why not replace wire forestay with a synthetic line? Lighter weight, no chaffing on jib, easy to make / repair...etc. Thoughts?

It's not class legal, but I totally agree that it should an option. I have built a few synthetic forestays and they have the benefits that you've mentioned.

These are the only two rules I saw that related (see below). As long as the synthetic forestay was at least the same diameter & strength as 1/8" 7x19 wire, seems to me there's no reason it wouldn't be class legal.

General Rule 15.1

"Wires as supplied by the HOBIE CAT CO. shall not be reduced in diameter. They may be increased in size. All wires may be shortened or lengthened with exception of bridle wires."

Hobie 16 rule 5.2:

"Pigtails may be changed or altered to increase strength only. They must connect at the mast tang and the jib halyard block in the same manner as the HOBIE CAT CO. supplied boat (except when the jib halyard is modified according to 4.1a).

You missed General Class Rule #1:
Quote:
1. ONE-DESIGN CLASS RACING
The design and development of Hobie Catamarans
are directed towards strict one-design
classes where the true test is between sailors
and sailing skill, and not boats. Any alterations
to the hull form, construction, equipment, spars,
sails or running rigging, as supplied by the
builder except as is specifically authorized by
these rules, are a breach of these rules, both in
spirit and in substance, and are prohibited.


Emphasis is mine. Basically, if it's not specifically allowed, then it's not class legal.
