The most common approach is to add a Sunfish rig. And when done you can sail the boat with either of the rigs. First, some useful numbers for this conversion:
• The Sunfish mast is 2.25 inches in diameter
• The mast sits in a hole that is 10.5 inches deep on a Sunfish. It will be set deeper on the Potter.
• Hole size for the mast on a Sunfish is 2.46 inches in diameter.
To make the conversion, a mast sleeve needs to be installed to receive the Sunfish mast. I used standard available Drawn Aluminum Tube 6061 T6 with a 2.5-inch OD, 0.065 wall thickness, and 2.370 inch ID. This gives a little wiggle room so the mast drops down easily. Start with about 3 feet of tube length. (The height from the v-berth to the top of the cabin is about 2’-6.”) The final sleeve length may end up being longer depending on what kind of mounts you use at the top and base.
The mast sleeve needs to be secured at the base on top of the v-berth. It will be the forward of the original compression post. This can be done in a variety of ways. It can be a female version using a 1-inch thick piece of wood with a 2.5-inch hole. Or a male version with a 2.37 (2-3/8-inch) dowel, sanded down to fit. Both will have to be secured to the berth (rivets, bolts, or screws)—some way to secure the mast sleeve so it cannot be pulled up after installation. An “L” bracket will work with the female design. One screw going through the sleeve and into the dowel will work for the male design.

POTTER WITH A LATEEN RIG?
Our editor-at-large Larry Brown is 75 now…an increasingly ancient mariner. He’s sailed various Potters since the early 1990s.

Choosing a Boat Design
Sitting hove-to in 30 knots of wind was not how I anticipated spending my opening day.
RECONSIDERING ROSIE'S RIG
It was a typical hot Mississippi day when I walked into the Ocean Springs Yacht Club to cool off. I had just spent two hours bent in half while working inside the cabin of my West Wight Potter 15. I was stiff and drenched in sweat but feeling proud of myself. I had just turned Rosie into a lateen-rigged catboat.
When we were kids, we had a cocker spaniel aboard during summer cruises. The dog apparently had a massive bladder, but we kids were happy to row her ashore when nature called. We thought boating with a pet was terrific…but did our folks have a voice in the matter?
Some fiberglass boats, like Boston Whaler skiffs and MacGregor power-sailers, are built with integral flotation foam between the inner and outer laminations. Roger MacGregor was willing to flood his water-ballasted boats just to prove that they would not sink—and you can still find his old sales videos if you want to see for yourself.

MAKING THE SWITCH
Following are some methods for adding a Lateen rig to a Potter 15. Most of the photos are of my boat, but some clever ideas from others are included as well.

Hmmm. I’m in Milwaukee, Wisconsin, with a nifty camp-cruiser sailboat on a trailer. I have a daughter on a sailing lake in Michigan, and another daughter on Long Island Sound in Connecticut.
