Heavy Seas Yacht Description

"HEAVY SEAS" Is a 2004 65' Pacific Mariner Diamond Edition Pilothouse Motoryacht on the Great Lakes! She is hull # 39 of 66 and was designed by two very talented west coast naval architects. Her hull was designed by a master – William Garden. Garden has been building and designing boats since about 1935 and few people alive know more about boat design and efficiency  The exterior and interior were designed by Greg Marshall, who has many mega yachts to his credit.  The Pacific Mariner 65 was conceived by boat builders who want to give the American public an affordable, reliable, low-operating cost boat that would be versatile enough to operate at displacement speeds for long distance cruising or at 22 knots for long weekend cruising. She is  big enough for six, plus has a cabin for crew. You owe it to yourself to view the "HEAVY SEAS" and see what she has to offer.
