There really isn't much of a standard.

If it's a neoprene skirt, 1" off either way is not even noticeable. Buy the skirt, and see if the dealer will sell it with the understanding that you may return it (unused) if it doesn't fit right.

: Can any one tell what the standard size is for a small cockpit and does that
: include the 3/4" lip (or not)? I have heard that Seda small size is
: 16" X 29" and that sounds good to me, but does it include the
: lip? Any advice on size, I am 5' 10" and 145 lbs building an 18' sea
