Seamaster 27 ‘Ruby’ SALE AGREED


Please Click Here for Printable Details – Ruby

This was the most popular craft produced by the Seamaster factory, and was built between 1965 and 1974, during which time over 600 were completed. The Seamaster 27 is an excellent river, estuary and inshore boat with a hard chined hull that tapers to a shallow vee towards the stern and has a moulded keel. ‘Ruby’ (previous name ‘Jack High’) is a good example and is well equipped for trips and holidays on the river. A full out of water survey was commissioned in February 2023 in which numerous recommendations were made, but due to the owner’s change of circumstances, these have not been carried out (full details available on request).
We are open 7 days a week for viewings, so please contact us to make an appointment.
