The J/109 Class Association Forum

I am writing to document how to lift the long stbd floor piece to obtain access to cabling. Not that difficult, be careful not to break screws.
1a. Remove a couple of screws, go buy replacements. After 20 years of abuse, they are fragile. There are two lengths, most are the same length with only 3 ...

Mystery solved, the previous boat owner replaced the SS209 with a near identical looking product that does not have the delay.

I am going to replace it with the SS209.

This advertised to stay on for 15 seconds to sponge the bilge.

Mine does not do that. The entire on interval is as short as 3 seconds, enought to lower the water level, and then over 15 minutes the water comes back in and it ...

Weld repair successful. $99

Lesson learned:
- When installing synthetic lines, don't lead the middle lifeline through the bow pulpit to the bow. Instead terminate it on a friction ring before the pulpit, then lash the friction ring to the turnbuckle at the front of the pulpit. When done this way ...

I have a similar problem. The screw under the port side bow pulpit, with the wire going through it, spins as I tighten the nut.

I am wondering if I should pre-order a part before I remove the pulpit and bring to a welding shop, or maybe do all four. This is the second position on the pulpit that ...

Count you in! Thank you for the thoughtful questions.

On class racing, no advantage. If my proposed rules are accepted, the J/109 would be upgraded as a true dual battery system with additional ABYC requirements like fuses, plus wiring and switches so our boats can fully operate on one battery if ...

This caught me by surprise, will add it to my annual to do lists, that our vangs require almost annual maintenance. The primary culprit is the interface between steel and aluminum. In addition to potential product failure, if you allow these screws to deteriorate you will not be able to get inside ...

I want to share how highly I think of Crew Manager, the application Bill Kneller created and sells. Since my team and I started using it, I make fewer communication mistakes with crew, spend less time coordinating logistics, and on the whole, more crew are participating in races, 20% or more by my ...

I did not, Thank you.

Please describe how the bob stay retraction is rigged inside the anchor line to fully retract. How long is the elastic line? I am stumped believing the elastic needs to be at least six feet long to make the necessary retraction of the bobstay, and don't quite see the best way to do that inside the ...

Putting aside what Yanmar publishes, when do the engine mounts need to be replaced? I have a 2007 J/109.

Any advice how to do it?
* DIY project?
* replace them all, or just some?
* access to specific bolts?
* ideas to support the engine?
* in the water / out of the water when replacing?
* how to ...

The insulation is falling off the port side wall of my engine compartment, partially the glue failed and in one spot the insulation has ripped off the pad, perhaps indicating the insulation is fragile.

Has anyone done this repair before?

Is the insulation or glue special?

If I go through the ...

I can apply the etching paint on top of powder coat?

I am struggling removing the white paint. I am using "Klean-Strip Aircraft"
