The J/109 Class Association Forum

My 109 came with 3 big batteries and they are end of life. Planning to go to two to save weight. Class rules are a min 2 lead acid batteries with combined min 150 ah.

Question, what is the best set up for those two batteries given boat is mainly used for local and coastal racing, some overnight ...

Looking for a ride for the 2025 NAs. I co-own a J-109 named Tangaroa in San Francisco Bay. Would very much love to race one 109s one design and especially NAs in Chicago as we don't have a one design fleet in SF. 40 years racing experience on boats of all types - mainly SF Bay and West Coast. I'm ...

Looking to sell or trade. Looking for a #4 jib, a code 0 spinnaker, a 120 SM spinnaker.

Quantum Kevlar class mainsail. It says 2014 on it. Good shape.

$500 plus shipping. I have pics. I am in the San Francisco Bay Area. DM me if interested.

Hi Dan, I have 2 mains I am looking to sell. Both are in good shape for their age. The boat name before I bought it was WISC, based in Chester Nova Scotia.

Both standard 2-reef racing mains, with plastic slugs (don’t know what an Antal looks like). Fine delivery mains or racing club races to save ...

What’s the right length of the pole for the Genoa? Thinking of doing same thing for windy double handed races here in SF Bay

Is there a go to kit for repairing deck dings that reasonably matches the color for the J-109? Or an alternative?

Looking for best practice for cross sheeting the jib sheets for racing, as we do on J-105s. On the 109 the sheet coming out of the turning block ribs on the cockpit coaming. Wondering if there's a standard wedge for the turning block to raise it up, or maybe use a double block, or just put a ...

Now that we are end of season maybe there's a few of you that want to unload J-109 racing sails. I'm looking for main, spinnaker (108 SM and/or 120 SM) and class jib, as well as a genoa and possibly a code zero. All for racing in SF Bay. Ideally less than 3-4 years old and/or really good condition ...

HI Dan the Ronstan Medium Rope Bags will fit in the space on the cabin top parallel to the hatch and forward of the winch and rope clutches. There's another J109 in The Bay Area that has those, and on quite a few J-105s have them installed there. I have not installed yet. I did put three of them in ...

Wow that's generous. J105s can fetch many $000s to charter for a major regatta here, not including all those other costs.

I'm curious if chartering J-109s for event is as common as it is in the J-105 and other J-boat fleets.

I am considering making my J-109 based in San Francisco available for charter. It's a 2007 and in process of getting set up for go-fast. Bring your sails or let's negotiate new sails vs charter ...

Hey Dan, can you share pics of what you finally came up with for your inhauler set-up? I am starting from scratch. Thanks, Dan

Hey Forum,

Looking for pics and advice on best jib sheet in-hauler set up. Location is SF Bay, so often windier conditions. My new to me 2007 J-109 did not have it.

Hey Forum, questions on poling out jib and asym spinnaker

1. What's the right length for a pole for a standard class jib for sailing wing on wing?
2. Where to put a bail or track on the mast - inches from deck for example.
3. Anyone use a pole with asym spinnaker? What length is the pole and ...

Thanks Mvallus, the question now is whether there is too much rake, causing the backstay to appear to be too long. Is your rake measurement in line with the Quantum or North tuning guides? Have you done a rake measurement using the main halyard hanging down with a weight?
