Our History

Seamark Nunn® is now one of the longest established family-run boating businesses in the UK, having been originally started in 1961 by Mike & Rosemary Nunn. The company emerged as a boat building and chandlery business to support the growing boating community on the Suffolk & Essex Coast. From its inception, as well as offering a well-stocked chandlery, the company built up a solid reputation for fast racing dinghies in wood and later GRP, and during the late 1960s and 1970s was a favourite builder for the OK Dinghy, Solo and Optimist, the latter of which many were exported to Europe. From the early-1980s the company began its involvement with the sales and servicing of outboard engines, and we are now recognised as the leading outboard dealer in East Anglia. We started selling chandlery products online as far back as 1999 and our website now delivers a significant proportion of our total business.
