Hi both, no real need to know the number, but it would be nice to know. I have most of the paperwork from when the boat was first built. In the original Certificate of British Registry it say official number 35728. Name, Gabbo. Built, Little Hampton When Built, 1971. Registered 1972 Macwester Maine Co Ltd. Owner, Marion Chambler, House wife, Kenneth Chambler Medical Practitioner. (and the address in Healthfeild Sussex) It was later sold and the name changed to Malabar. It was in Chichester for some time where it was converted to a “live aboard” in Chichester Harbour and the name changed to Lavantian. It is still called Lavantian. Converting it back from a “live aboard” has been quite a task, the hull was lined with one inch polystyrene, then plastered over! A wood burning stove was put in the front between the bunks and sheets of steel bolted against the glass fibre lockers.In short the boat was in a real mess when I bought it. The only redeeming things were, the hull was epoxied, and a new Beta 35hp engine.gearbox shaft and prop were installed, and all the standing rigging replaced, then the boat went almost no where, the engine/gearbox/shaft and prop have only done 370 hours. I paid less than the cost of the engine for the boat, but have spent a lot on trying to update the boat and replace all the old galvanized steel work, still it keeps me active.
