Sheridan Marine of Moulsford on Thames, Oxfordshire (who stock just about every genuine spare made for Freemans), run an owners club, and have social gatherings at their premises on the Thames at Moulsford. They publish a newsletter, mainly full of advertising, but also lots of intersting tips and history of Freeman.
You can visit www.freemancruisers.com, or phone them on 01491 652085. Out of interest, they are planning to start building the Freeman 24 again.
