Mast Ram - Proteus

Mast Ram for your 11mm mast, specifically designed for the Proteus.   3D Printed parts fitted on 30mm M4 Stainless threaded rod

This part differs from our standard rams in that it is on a 4mm threaded shaft rather than the standard 3mm, and it does not include a Holder as the Proteus 3D print includes a 4mm hole for the Ram Shaft.

Modified 15 June 2026:   The thumb wheel is now fitted with a brass insert to improve the fit and usability of the Ram

The stainless steel shaft  fits through the moulded hole in the printed mid section of the hull and held captive by the knurled nut used to adjust the Ram.   The Ram clip lightly clips around the 11mm mast section holding the mast secure while you are rigging.

This part may fit other boats, but please note that it is designed specifically to fit the Proteus boats using the PJ Sails  PW15B (40mm) gooseneck fitting
