J/9 PROGRESS UPDATE

J/9 daysailer hull mold
(Newport, RI)- The J/9 hull mold was recently completed at CCF Composites and is now being waxed in preparation for the molding of hull #1 next week. In the picture, the contrasting boot stripe can be seen as well as the insert for the rudder post/bearing. The hull stripe is 100% flush with the hull surface so that the finished molded boot-stripe will also be flush with no marks visible. A separate transom mold fits on the back of the hull mold and is precisely aligned with 6 round keyways.

J/9 deck plug

Deck Plug Update

Symmetrix Composite Tooling recently applied a custom-mixed nonskid to all the horizontal surfaces of the J/9 deck and cockpit. Four different nonskid samples were tooled up, with molds taken from each and subsequent parts molded and tested, before the winner was selected. Symmetrix is now adding the final finishing touches to the deck plug before it is transported to CCF later this week. 

J/9 Specification Update

With the North American sailboat market recently importing more new sailboats than building domestically, we set out to reverse that trend with the J/9. Most of the content and key J/9 components are being supplied and supported by North American companies with extensive J/Boats experience.

Composite Materials

Quality composite construction starts with high-quality composite materials. The J/9 composites are sourced through Composites One, the largest North American distributor, whose regional office/warehouse is nearby in Bristol, Rhode Island. The fiberglass used in molding the J/9 is manufactured by Vectorply in Phenix City, Alabama. The Corecell core is produced by Gurit in Quebec, and the resins are made by AOC Resins from their facilities in Tennessee and Ontario.

J/9 keel profile

J/9 Keel

A key contributor to J/9’s exceptional stability is the all-lead, L-shaped, low VCG (vertical center-of-gravity) keel featuring a foil-shaped, wedge bulb that increases stability (vs. conventional keels) without increasing draft. The modest 4.9’ draft allows the J/9 to sail in most areas, and an optional 3.9’ shoal keel is available for even skinnier water access. The J/9 keels are being produced at Broomfield & Son in Rhode Island.

Jib Furling System

The J/9 design philosophy of keeping things simple is carried through to the sailing hardware and systems. In-deck jib furlers might look great, but for less weight, less cost, easier maintenance and much less friction, nothing beats a high quality above-deck furler like the Mark IV Unit 0 from Harken, Inc. of Pewaukee, WI.

J/9 Spar Package

After carefully considering several spar options, Sparcraft USA (Charlotte, NC) was chosen to supply the J/9’s spar package. The Sparcraft extrusions (mast and boom sections) match the J/9’s performance profile, and the company’s ability to anodize and powder coat the spars provides the most durable painted finish available.  For more J/9 Daysailer information Add to Flipboard Magazine.
