The 48 SRD is a natural step up from the successful Shannon 38 foot SRD. Once we sea trialed the 38 it was very obvious to me that I had a hull design (patent pending) that could travel long distances in every wind and sea condition. Not only did we have a yacht that broke all barriers concerning fuel economy and range it did so using almost half the horsepower compared to conventional hulls. The SRD is not some lumbering displacement hull that travels at only 8 knots and requires some method of stabilizing to prevent excessive rolling in a seaway. It is also not a planing or semi-displacement hull design that requires frequent fuel stops and limits cruising range. And, the SRD design also offers shoal draft making the Inland Waterway, Bahamas, Chesapeake and Great Lakes totally accessible. With a range of over 2500 miles the Shannon 48 SRD at cruising speeds of 12 knots or more will travel from across the Atlantic without refueling.
