Back to the original question. THE 1956 Chris-Craft 17' Sportsman:
If you have a copy of
"The Real Runabouts III", by Bob Speltz, on Page 274, there is a picture and specs for that boat...and all the other
Runabouts and
Utilitys offered by Chris-Craft in 1956. The Sportsman was considered a
"Utility".

NB
EDIT: Cabin Cruisers not included.
