The ISLANDS 17 is most likely a 'splashed' copy of the TANZER 16 with a reverse transom giving it a slightly longer waterline length. Those who have seen both boats have all commented on the striking similarity, especially in the case of earlier boats by Ocean Yachts. The later version, built by Sumner, (also called SUMNER ISLANDS 17), has a cockpit liner with added flotation as well as number of other modifications.
Thanks to 'Dave from Maine' for additional information on this yacht.
