"Rocky" is a West Wight Potter 19, year 2000 model. I purchased the boat used in November of 2001. The former owner had only sailed it a few times, had performed no modifications, and kept it garaged. It had one mishap (a capsize) in its history, but International Marine handled all required repairs and brought the boat back up to factory specs, so it was essentially new.

Potters reach their new owners ready to sail, but are pretty much "no frills" boats as delivered. Most owners modify or customize them somehow. Rocky now offers the benefits (?) of several popular modifications and a few minor mods that may be unique. By the way, I've tried not to overdo this: most sailboat manufacturers know what is best for their design. I have tried to keep things consistent with the original P19 look and feel, and only made changes or added things that really made the boat more useable or attractive without adversely affecting its weight, balance, or strength.

Important: The information here is not intended as any kind of a guide or recommendation regarding modifications that may be applicable to your (or any other) boat. I have tried to adhere to good design and construction practices, but if you choose to try anything you see here, you do so at your own risk. Anyone who seriously contemplates such work on their Potter should at least contact International Marine for support and further information. A wealth of information is also available at the Trailer Sailor forum at www.trailersailor.com, and through the various other sites on the Potter Web Ring.

 
 
  Keel cable
 
Detachable keel cable The standard boat has a stainless steel cable attached to the keel that runs up to blocks on the cabin top and aft to the keel lifting winch. The stainless cable tends to get in the way and cannot easily be detached from the keel. IM now offers a detachable cable as an option, but this was not available before 2002.

I replaced the cable with low stretch synthetic line and replaced the associated hardware on the keel with two eyebolts. A single block with removable clevis pin threaded on the line provides mechanical advantage equal to the original fixed block, and a single stainless quick link terminates the line. Materials:
  • Sea Dog stainless eyebolts, 2 each, Sailnet SEA080499
  • Scheafer Series 2 single block, Sailnet SCH02-03
  • Yale Ultra Low Stretch line, 1/4", 30 ft., Sailnet YCU14CRF
When putting together this mod, it pays to remember that the keel can exert tremendous force if allowed to drop suddenly. All parts should be sized to withstand much more force than the weight of the keel alone.
 
  Keel cap
 
Removable keel cap Once the cable is out of the way, it makes sense to have a useful cap on the keel. This one is made of 3/4" genuine mahogany, with a 1/4" deep channel routed in the bottom to fit securely on top of the keel. An eyebolt on each end with shock cord strung on it holds the cap down. The hooks on the shock cord hook onto the eyebolts on the keel. The cap can serve as a small table or a seat and is easily removed for sailing.
 
  Added storage
 
  The P19 has lots of storage space, but some of it is difficult to reach or use efficiently. Rocky has these minor mods to improve the use of space:
  • Storage bin added under vee berth center seat
  • Storage bin in the countertop to the left of the stove
  • First-aid kit and electrical accessory kit attached to cabinet doors
  • Fabric storage pockets to hold miscellaneous items
  • Small bookshelf
  • Cooler shelf under vee berth
  • Jib bag
Vee berth storage bin
Vee berth storage compartment This is a Rubbermaid bin (#3921). It fits in a hole cut under the seat cushion and lined with Flex Trim. The bin is removable, watertight, and you can't tell it is there with the cushion in place. Removing the bin provides access to the automatic bilge pump and the depth sounder transducer.
 
Countertop storage bin
Countertop storage compartment The storage space to the left of the stove is essentially wasted in the stock boat. A drawer would be nice there, but for the money and effort a bin with a lift-out tray seemed like a better idea. The bin and tray are made of Luan plywood; a mahogany cover fits over it. The space works well for tool and small hardware storage.
Countertop storage compartment  
 
Cabinet door storage
Cabinet door storage An Orion "Weekender" first-aid kit is just about the right size to fit inside the port cabinet door. I tried fastening it several ways; in this picture it is held on with Velcro strips. This didn't work out, so now it has a snap-on strap across it.

A plastic storage container from the hardware store fits the starboard cabinet door. It is held in place with wood screws.
 
Storage pockets
Storage pocket This was a rainy-day project that used up some surplus Sunbrella. Six snap-on storage pockets (one at each berth and two on the aft cabin bulkhead) store books, binoculars, spare lines, etc. The one shown is typical.
 
Bookshelf
Bookshelf This removable bookshelf is made of mahogany scraps and mounts on two small removable-pin hinges. It is big enough for a couple of paperbacks or small hardbacks. A hole drilled in one frame holds a pencil.
 
Cooler shelf
Floor leveller The space under the port vee berth is big enough for a cooler (theoretically), but the bottom of it is sloped by the hull. This plywood shelf gets the storage space off the floor and level. The plywood sits on struts shaped to the hull contour and epoxied in place.
 
Jib bag
Jib bag Since Rocky is kept in a slip, it makes sense to keep her rigged for sailing all the time. This bag stores the jib on the foredeck saving a little cabin space and all I have to do when rigging is take off the bag and attach the jib halyard. The design is based on one by Sailrite Kits, modified for the small jib.
 
  Electrical system
 
  Potters have several factory options available when it comes to electrical power, but Rocky had just the basics: a single storage battery, one interior light, and navigation lights. I added:
  • Two 12 volt outlets
  • Automatic bilge pump
  • Reading light over vee berth
  • Circuit breaker panel
12 volt outlet
  A 12 volt accessory receptacle is available as an option on new boats, but was not included on mine. Nothing fancy here; just a standard automotive outlet with cover. I added one outlet on each side of the cabin.
 
Automatic bilge pump
Automatic bilge pump This is another factory option that was not included with my boat. The pump has an integral float switch and is mounted under the vee berth center seat. A switch behind the galley stove controls it. An automatic pump is essential for a boat kept in the water all the time; however, it would only run in the event of a serious problem.

Note: This may not be the best place for the bilge pump. The factory pump is placed near the stern, but the vee berth location is easier to plumb. The water level in the bilge would have to be fairly high before the pump would turn on.
 
Reading lamp
reading lamp The vee berth area isn't lit well by the light over the stove. This gooseneck lamp provides good light in that area, and was easy to wire and install after the wood trim on the mast partner replaced the original metal conduit. This lamp originally used a 10 watt halogen bulb, since replaced with an LED array. The 15 LEDs (12 white and 3 red) use about 1/10th the power of the original bulb, and deliver nearly as much light.
 
Circuit breaker panel
circuit breakers The stock Potter uses three switches and fuses to control the nav lights. These were becoming intermittent on my boat. This six breaker panel uses Blue Sea breakers, with three breakers replace the original switches and the remaining breakers providing circuit protection for the fishfinder, cabin lights, and the 12 volt outlet.
 
  Stern anchor
 
Stern anchor I almost always sail alone, and it was a hassle to go up to the foredeck just to drop a lunch hook. I bought a second anchor and added a deck plate in the rear deck with a chain pipe mounted on it. The anchor rode drops into a plastic trash can mounted on the inside of the transom.
 
  Lines led aft to cockpit
 
Lines led aft Leading the halyards and other sail control lines back from the mast to the cockpit is a fairly popular P19 modification, and Potter owners have found many different ways to do it.

My solution only leads the jib and main halyards and the topping lift sternwards, but it is very cheap and doesn't call for drilling many holes in the cabin top. The turning blocks at the bottom of the mast attach to stainless shackles that replace the forward mast step pin, and the turning blocks at the cabin corners attach to the U-bolts for the mini-stays. The lines are secured at cleats thru-bolted to the cabin top. The original cleats are still on the mast for emergency use.

This is admittedly not as elegant or as sophisticated as found on some Potters. Judy B's design, for example, is much more suitable for blue-water sailing. But this cheapie approach is probably safe for the protected waters where I sail.
 
  Miscellaneous modifications
   
Weather instruments/Clock
instruments These three instruments came from the local swap meet for $5, and are mounted on an African mahogany base cut to fit the aft cabin bulkhead. They are mostly for show but are fairly accurate.
clock I had an old chronometer from a boat I sold years ago. It had a bad movement, but the case was OK. I removed the back, replaced the movement with a quartz movement from a hobby shop, then mounted it over the compass back. It works, and better yet, hides the compass case. It does not affect the compass readings.
 
Oil lamp
Oil lamp Ebay provided a cheap gimballed oil lamp, which is kind of nice on gloomy winter days. It provides some heat as well as light. It is trivial as modifications go, but I recommend it to anyone who spends much time hanging out on their boat during bad weather.
 
Pole clips
Boathook/pole storage I added three sets of "Clipper Clips": one set on the side of the port cockpit seat and two inside above the port quarter berth. The outside set holds the boathook when underway. The inside set holds the mast raising pole and the boathook when the boat is at the dock.
 
Mast partner trim
Mast partner trim As delivered, the P19 has electrical cables snaked up the mast partner through a steel electrical conduit, which had rusted some and was chafing through the wires at its ends. I removed the conduit and routed out a strip of 3/4" mahogany to fit the mast partner. The cables are hidden and secure and the wood looks a lot better than the old conduit.
 
Sink drain
Sink drain The original sink drain emptied into a plastic jug under the sink, and had no plug and did not allow the sink to drain properly. I tapped the thru hull for the bilge pump to allow the drain to drain overboard and replaced the drain fitting with a standard bathroom vanity fitting.
 
Tiller tamer
Tiller tamer "Real" tiller tamers cost around $30. I added a jam cleat to the underside of the tiller. A bungee stretched between the stern cleats and snapped into the jam cleat tames the tiller satisfactorally, and cost nothing, since I already had the jam cleat.
 
Spare tiller
Spare tiller The stock tiller needed refinishing; this one kept the boat functional while I did that. It is shorter than the stock tiller, so works better if there are a few people in the cockpit.
 
Tiller cover
Tiller cover After refinishing the tiller, it made sense to make a Sunbrella cover to protect it.
 
Companionway door
Companionway door This is not a modification as such, but maybe is an improvement. The old companionway door was peeling. This new one consists of two plys of 1/4" Luan with a layer of fiberglass cloth between them, epoxy coated and varnished. It is stronger and a better fit than the original.
 
 
Bow bitt
Bow bitt The single cleat at the P19 bow is a bit skimpy for a boat that is kept in a slip. This stainless bow bitt is large enought to accept a few lines at once. It is backed up by a 1/4" mahogany plate and a 1/8" aluminum plate.
 
Companionway seat
Companionway seat A passenger can sit in the companionway with this seat in place. It is made of epoxy coated 3/4" plywood, with a padded center section made from closed-cell foam, fiber batting, and Sunbrella (waterproof, and it floats). The bottom is routed out to fit the edge of the companionway.
 
Motor lock
Motor steering lock Generally, it is easier to steer the boat with the tiller and the motor locked pointing straight ahead, but the factory steering lock on the Nissan 5 is intended to just add friction to the steering. It does not hold well when cinched down all the way, and may strip if tightened too much. For a more positive directional lock, I replaced the motor bracket pivot bolt with a longer one and added a homemade aluminum bracket between the pivot bolt and the motor body. The bracket is attached to the new pivot bolt with a lock nut and to the motor body with a new stainless bolt (added to an existing hole in the motor frame) and wing nut. With the bracket attached, the motor points straight ahead all the time with no side play for easy tiller steering. Detaching the bracket allows normal outboard steering.
 
Bottom paint
Bottom painting After I had Rocky a few months I decided to paint the bottom; not so much because of marine growth problems but because of potential hull blistering. I ultimately put on an epoxy barrier coat (Pettit Protect) followed by two coats of ablative paint (Ultima SR). The paint has been on two years now and only required a little touch-up after the first year.

The logistics of bottom painting are tricky for a trailer boat this size. For larger boats, the only option is a boatyard. Trailer boats can be painted at home, but it is difficult to reach all parts of the hull; notably the parts that rest on the trailer bunks. I opted to paint what I could with the boat resting on the bunks, then jack up the hull and support it on 2x8 rails and temporarily remove the bunks to reach the rest of the hull as shown here. I did not paint the keel.

I do not really recommend this method. It worked for me, but the risks are high: getting a hand squished or dropping the boat and damaging it. Various other owners have used this or other similar techniques with success, but on the whole I believe a boatyard that can put the boat proper jackstands and that allows do-it-yourselfers to paint their boats may be the best (and is surely the safest) bet. For new boats, International Marine offers bottom paint as a factory option.
 
Quarterberth pillows
Pillows Another scrap Sunbrella project, these little pillows fit in the settee space better than those at the local discount store.
 
Sunshade/boom tent
Sunshade up This boom-supported sunshade may someday evolve into a boom tent, but no promises... measuring for a boom tent is harder than it seems. These pics show the sunshade up and stowed above the port vee berth.
