1) Although the sail track entrance slot is milled into your mast with a milling machine, it was not done with 21st century digital technology. There is some variation in the height of the sail entrance slot from one mast to the next.

We fabricate our MastGater with rods that extend from the top and bottom of the mounting plate. The rods mimic the shape of the bead extruded to the inside of the mast track for a smooth transition between the mast and MastGater. The majority of masts require the length of the rods be trimmed at installation to accommodate the difference in the height of the entrance slots.

2) A few owners of late model Catalina 25's (late '80's ->) report that their masts were machined like a C-250, i.e. the sail entrance slot was only machined on one side of the mast and total height was only about 2". If that is the case for your mast, order the similar C-250 part, #E2011 pictured below under "Required and Related Products".
