Has anyone changed the base plate on a Mac 26 that rotates to a non rotating mast. If so, how was it done

Why don't you want it to rotate
May be easier to limit the rotation instead by cleating it off the bottom of the boom near the boom vang using a mast rotation spanner.Not sure if the M has one.

Using halyards aft towards cockpit causes the mast to rotate to port when using it.

How does this affect sailing? Also Terry in BC has a slick setup for rotating his last when it doesn't cooperate (check mods or posts for pics, pretty sure there's a few on here) I just give the boom a quick shake after a tack.

My mast turns in the same way with halyards lead to cockpit bevore and after the mod.

Means in light winds no rotation, in a good brease normal rotation.

Sounds like the routing of the halyard may be too far aft? Could also try upgrading the mast bearings to help a smooth rotation

My halyard is next to the mast. Never had a problem with it pulling the rotation to port.

Same here Russ with no issues. It can get a little sticky through a tack in light winds but usually shakes itself out within a min or I do it manually from the cockpit.
