Miscellaneous information
From Terry Forshier on 01/22/2000:

Keel configuration reported about 1/2 knot faster on average.  Overall production between 1977 and
1984 over 350 followed by the O'Day 31 in continuing original numbers sequence from the 30.  The
main difference being the stretched version with stern modifications; about 150 of these were
produced.  Interior layouts started with the traditional folding center table and changed in the 80's to a
circular U-shaped settee.
