11.25m Gaff Ketch,Holts design and build,1977

‘Martha Kathleen’ is a massively strong gaff ketch designed by Arthur Holt and built for my parents by Holt and James, Heybridge, in 1977. She was the third hull to that design, a beamy tradition boat with plenty of internal volume and excellent seagoing qualities. Being intended for short-handed cruising of the Western Isles she has a gaff ketch rig, breaking the sail area down into easily managed sails, a powerful Thorneycroft 50 engine and lots of space for children and grandchildren. Wide open laid iroko decks with a simple coach-roof for’rard of the mizzen and a deep and secure self-draining cockpit aft of it. By their mid-eighties my parents were unable to use her much and we brought her south in 2005. Since then she has had considerable work cleaning out her bilges and re-ballasting, re-caulking, running rigging replaced and standing rigging enhanced, new working sails and light air jib from James Lawrence and an asymmetric reacher from Jeckells. At present fitting out under cover in St Osyth, her home port is Brightlingsea.
