J-22  Coaming Project

The goal is to decide and approve this proposal in days or weeks as opposed to months or years.

We are seeking Official International J-22 Class permission to use two simple defined pieces of fiberglass to make old boats a lot more like new boats while doing absolutely NOTHING to affect the performance of the J-22 One design Sailboat.

At the very least we would like to secure immediate J-22 Class approval for the installation of a prototype set on a well known sailor's boat so that boat may race in regattas at any level while other sailors have the opportunity to view the modification and either decide to accept or object to its use on any Class Legal  J-22.

Purpose

     To create a one design retrofit which will allow owners of older J-22s to enjoy a functional, simple to install, maintenance free cockpit coaming.

     To introduce the coamings to the J-22 class members as an International J-22 Class Approved modification

 

Goal of this webpage

     I want the reader to come to this conclusion: Fred has built a prototype and a set of molds and has built appropriate fiberglass coaming boards for the Racing International J-22.

    I want to cause solutions to every concern such that:

1.  There is no doubt about the legality of the parts for J-22 racing competition.

2.  The only remaining concern is making certain any builder who wants to provide these coaming boards will be able to compete on a 100% equal footing with any other builder.

3. Fred wants to be allowed to be a supplier of class J-22 Class legal coaming retrofit kits

 

Parameters

     The coaming must serve the same functions as the wood coaming with respect to keeping water out of the cockpit.

     The coaming must allow a spinnaker cleat to be mounted in the usual Class Standard Position.

     The coaming must not change the sailing characteristics of the boat by changing the deck stiffness.

     The coaming and its fasteners and caulk should weigh about the same as the teak coaming and its fasteners and caulk.

     The coaming should be durable

     The coaming should not significantly alter the appearance of the boat.

     The coaming should be about as comfortable for seating as the new fiberglass molded coamings.

     The coaming should be of a defined laminate and built to a standard weight.

     The coaming should be easily installed by a typical boat owner using simple hand tools.

     Installation of the coaming should not cause any harm to the J-22 and the coaming should be able to be removed by those owners who desire to return their boats to the classic teak coamings.

 

Sales pitch from the designer / prototype builder

     This prototype and mold was built while absolutely convinced I could simply show it to other fans of the J-22and receive instant support for its use. I sail J-22s and have sailed J-22s since the first "two digit" sail numbered J-22s arrived in Austin. I have watched the development of the boat and the racing class and I have maintained literally hundred's of racing J-22s.

     When J-24s and J-22s first appeared with plastic toe rails, many sailors instantly decided to retrofit their older boats. The change to plastic was well received. sailors do not generally like to maintain teak rails. The original teak toe rails on most Texas J-22s have weathered to the point where the teak plugs are gone and the screws are sticking up above the remaining wood.

     The first 1200 J-22s came with a teak coaming board on each side of the cockpit. The very newest J-22s have a plastic molding where the original J-22s had teak coaming boards.  The teak coaming boards on most of the Texas boats are severely weathered and worn away. Some coamings are fractured and many have uncomfortable or even dangerous splinters waiting to find homes in lines and crewmember's skin and clothing.  Replacement of the teak is a difficult process involving a lot of chiseling, a very expensive thick piece of teak, woodworking tools and a skilled artisan.. Owners whose goals include "getting rid of all the #%&@##! teak would love to have a better option than "replacing everything but the coaming boards. No one, according to my limited knowledge,  has offered a practical plastic one design retrofit for the J-22 teak coaming rails and the class has not approved any modification what so ever to the teak coamings. (Rumor has it some racing J-22s, without first seeking class approval,  have already been modified to match the new decks. I am trying to get ahead of the problem by creating a standard solution.)

     The owners of the old boats would like to believe their old boats can be competitive with the newer boats. One definition of even competition might be that the owner of an older boat be able to make the older boat "just as pretty" and "just as comfortable" as the newer boats.

     Specifically?  The owner of J-22 number 307 said, "I want plastic so I don't have to maintain old teak ever again. I want something nice to sit on like Mark has on his new boat." (Mark has a deck with a molded coaming)

     As a long time racer  / cruiser of the J-22, I built the exact coaming I believe is appropriate. I built a prototype and I built a mold because I believe I have created the exact thing which solves the problem of "Retrofitting a J-22 coaming with a fiberglass coaming while maintaining the integrity of the One Design Racing J-22."

     My proposed coaming rail kit will have zero impact on the order of finish in any race at any time. My proposed coaming may cause some extra boats to participate as the sailors will be more comfortable and more likely to enjoy themselves.

 

Structure

     So far I have only built a plug and a mold. I still need to finish the mold by removing a few high spots, polishing it, and waxing it. I believe the laminate will consist of  white gelcoat, a thin back up layer of resin and 1/32 inch milled fibers to prevent tiny voids from breaking out, 3 layers of 1.5 ox mat and two strips of 6 inch wide 10 ounce cloth. The cloth would overlap about 3 inches in the entire center of the length of the part. I also plan to install a backing plate pre-tapped for #10 fasteners appropriate for a Harken 150 cam cleat. (or maybe just include the preinstalled cleat)

 

Installation

     The plan is based upon simplicity and the minimum tools a J-22 sailor may own or reasonably purchase. I believe it would be best to remove the screws and chisel away the old rail before installing the new fiberglass rails. The new rails are constructed such that a person could simply grind away about 1/2 inch of the old teak rail and install the new fiberglass rail over the old shortened teak. We have already tested our concept by using a Surform brand tool on another J-22. In fewer the fifteen minutes of work, we had the old teak sufficiently ground away to drop the new fiberglass over the old teak.

     The new rails should be adequately mounted using 3M 5200 sealant and six or seven self tapping #10 truss headed stainless screws.

 

Fred's Proposal

     I am not an authorized J-22 sailboat builder. For the last 30 odd years I have made a substantial part of my living by maintaining various "J" racing boats. I have no real reason to change that relationship described as "You build them and I fix them." I also understand that other suppliers have built many retrofit J-22 racing items and few if any have bothered to do as I am doing and seek approval before producing and selling parts for racers.

     I have dabbled in the creation of J boat retrofit parts and even sold many racing motor mounts for installation at the factory on J-24s. Link to photos

    My initial target guess price for this kit would be $600. I would happily build and sell the parts and maintain one design quality control as described below and for the short term, I will even try my guess price as the officially  set price. No other part builder original or aftermarket is building to an approved  set price . ( $650 with preinstalled Harken 150 cam cleats.)

     I would initially build and ship One design Standard parts to any builder for a set $400 plus packing and shipping price.

     I will build a set of tooling for any Designer and Builder Authorized manufacturer to use. That tooling would be just as the molds in the photos below. Mine have orange tooling gelcoat, at least 6 oz of mat and Iso resin, a layer of 2 mil Coremat, one layer of 1.5 oz mat, another layer of Coremat and at least 6 oz of mat. I tried to keep the Coremat away from the edges of the molds. I believe I could build a set of molds for $1000. That number may cover only the labor and not materials and shipping or perhaps I could accomplish the entire task for under $1000.  Particulars could be worked out if and when anybody seriously asks for a set of molds but I am willing to guarantee delivery in the US for under $1500.

 

Fred's Political View

     Background: The reader should be told I have served as a measurer in various sailboat classes since I was a teenager. I have also made a living both building boats and maintaining boats. Most of my life's work experience relates to maintaining sailboats that also race. I have always  worked within the One Design Rule system for any class where I believe improvements or modifications should be approved.

     Specific to J-22s:  This modification is not significant to the performance of the boat. The only reason any J-22 owner would make this modification would be looks and comfort. My only reason for seeking approval is a strongly held PERSONAL belief that ANY modification no matter how insignificant to ANY one design boat should be approved in advance of its implementation.

     I sincerely believe the officers of the International J-22 Class should have  no objections and quickly and simply "rubber stamp" this proposed fiberglass coaming. I have no idea why anyone would possibly object to this proposed coaming. I am only seeking approval because,  I do not believe it is proper for anyone to modify the boat in any way without prior International J-22 Class Association  approval.

     Whining about reasonableness: The plastic mounting blocks and extra pulleys for cross sheeting the jib sheets certainly affect the performance of the boat. I certainly would have asked before installing anything like them. The specially shaped custom blocks are not only being allowed, they are being supplied by after market suppliers as well as the builders.

     I am doing everything I know how to do to properly play within the intent and the letter of the rules. it certainly seems reasonable to expect superlative consideration for my superlative efforts.

Prototype parts sitting on the deck

The prototype parts are not really thick enough or made with the right layup schedule. For that reason and the fact this boat races and we can't install parts that may later be found to be illegal, the parts are sitting loose.

Plug ready to spray

This is to show what goes on in making a mold of this sort.it is a lot of work. Some folks who are involved in the J-22 Class approval process who don't build fiberglass things for a living may like information about what is involved.

Plug ready for gelocat

We needed to have an available boat and an owner who was willing to let us make a big mess all over that boat. In order to build the prototype rail we first had to remove the old coamings, then make a mock up of the prototype rails, then build a mold.. The owner had to be willing to let us have the boat for a few extra weeks

Partly gelcoated port mold.

This first layer of the mold has to be sprayed. This is more of a mess that has to be made on our willing owner's deck.

Gelcoat on port mold

This is what the gelcoat looks like from teh back side before fiberglass is laminated over it. Thee will be about 12 layers of fibreglass mat applied to this gelcoat before we pull our completly laminated mold from the deck.

Parts in molds

Here are the molds after they were lifted off the boat. The prototype parts are still sitting in the molds

Ends of molds

This view is just for detail. The parts are siting in the molds but the parts ahve been previously lifted loose. The parts are only prototypes. They are not made like the final product.

One part lifted out

Here is a mold with a prototype part in it and a mold with the part lifted out. When parts are made from these molds, the parts that come from the molds will need to be lightly sanded all around the edges, but every part can be easily produced in a fashion making every one virtually identical to any other.

Molds and prototype parts

From the angle shown, the prototype parts are indistinguisable from the coamings we are proposing. These parts only look like the parts. They will never be installed on a boat.

Close up of mold ends

Just a closer look. These molds must be sanded and polished and waxed before they can be used to make anything.

Deck from camera held over my head

This is the boat with no coamings. Since the prototypes were made and the molds were made we heve installed the new plastic toerails, regelcoated the entire smooth parts of the deck, painted Awlgrip nonskid, and shined up the sides a bit.

Cockpit with no coaming

The owner really wants to replace the coaming rails with something other than the original teak. The owner actively races and has seen the newer boats with no wood anywhere on the deck. The coaming project started out with the simple goal of producing something for this boat that is not wood, does not change the weight location, blocks water similarly to the wood, and does not abuse tender fannies.

View from port chainplate

This shows we have met our goals with respoect to similar water bolocking characteristics, We also molded in a space for a Harken 150 cam cleat for the spinnaker sheet..

Close up from port front

This part is neither screwed down nor caulked and it already fits nicely. There is nothing to catch sheets, sails, clothing or fingers.

Port coaming from cockpit

This gives a clean look and no fear of splinters when the crew goes over there to sit down.

Port coaming from cockpit

The black is modeling clay from the mold production process. The paret will be laminated such that it fits more tightly against the dech than shown. As it is, the space is about 3/16 inch and could easily be filled with 5200 sealant and lok just fine.

Port coaming aft end close up

The parts will not catch ropes. The backstay can still be led foreword with no problems.

Mostly, doesn't this look a lot more comfortable than the top edge of a narrow piece of teak?

Starboard coaming from chainplate

The starboard side from standing by teh chainplates

Starboard coaming from standing by winch.

Just another view

Detail of starboard front

The piece is sitting loose and it fits well already

Starboard front detail

Nice sneaker huh?? Lots of layers of paint on that shoe.

Starboard coaming aft view.

In the "ready to spray" photos you may have noticed radiating blue repairs. The cracks were caused by water leaking around the fasteners which encouraged the balsa core to rot. I am hoping the 3M 5200 and this coaming will help to prevent reopening of the repaired cracks.

Bartlett's J-22 in front of Bartlett Sails and Awnings

The boat is sitting in front of John's shop and local J-22 sailors have been noticing that John has had his boat refurbished.

The question has been, "Are those legal?"

The universal request has been, "Do whatever it takes to make those new rails legal. They look comfortable. I want to install some on my boat."
