Product Description
Not for Potter 14, which uses a DM-275 mast.
West Wight Potter-15  uses a DM-1 mast with a feed slot cut the length of 2 7/8" to 3" length.
Your sail slugs should be 3/8" or 9mm in diameter.  Smaller slugs will pull out too easy.

Our MastGate snaps into place to bridge the open feed slot.  No tools needed.
Made of strong durable nylon, dyed to a color of your choice:

Black is best for blocking more UV.
Orange is best for viewing.
White is the least expensive and you can dye it yourself.
Click on the selection button to see other colors.

Custom-built for the Dwyer Mast DM1 extrusion.  Now your sail slugs will not fall out during reefing or raising the sail.
Two optional set screw holes (6-32 x 3/16") were added to the gate plate for sailors who want a locking method.

 If you have a DM1 mast with a different slot cut length (less than 2 7/8" or greater that 3") , you may request a different length at
