Excelsior is the last surviving fishing smack of the Lowestoftfishing fleet and a member of the National Historic Fleet. She was built by John Chambers of Lowestoft in 1921 and worked until 1936 before being converted into a motor cruiser. In 2011 Excelsior celebrated her 90th birthday. During her time as a motor cruiser she was known as Svinor and sailed mainly in Norwegian waters before returning to Lowestoft in 1972.
She measures 23 metres long with a beam of 5.9 metres and is the last traditional sailing trawler able to tow a full-sized traditional trawl net. Excelsior was restored in 1989 and operates as a sail training vessel based out of Lowestoft, able to accommodate up to 16 people, with 12 sleeping berths.
