We'll be bringing the "Tybee kit" and yes it will include a GPS.

1) I have never sailed, let alone been to NYC
2) The commerical shipping traffic will pose navigational issues
3) This is an offshore race

I think the rules to exclude GPS's are silly in this type of race. Just my 2cents.

I looked around the site for the SI's but couldn't find them.

What other gear is not allowed? Can we use tackticks? Weather radios? Paddles?
