Re: Code Zero Modification for Halyard & Tack Line

This is an unusual request for the Technical Committee to rule on modifications for a sail configuration that is NOT Class Legal. It is the opinion of the TC that the J109 in standard OD configuration has the necessary deck hardware and rigging for the described Code 0 configuration. For option 1, a...

Propeller replacement

Over the last few years several boats have lost propellers or one of the blades. The Flexofold racing propellers that was standard on most US built boats are no longer in production, the classic blade from Flexofold will fit the racing hub if installed as a pair. The classic blades are class legal a...

Re: Lithium batteries for J/109 class

Thanks Dan! A very good summary of the issues we face approving Lithum Ion batteries. From a Class rule point of view the perceived weight savings may be the main issue, we do not want to get into an arms race spending three times as much to potentially save 80 - 90 # and on top of that have severe ...

Harken Vang-Master

The TC was asked if the Harken Vang-Master was approved as a replacement. Over the years of production the J 109 was delivered with the Hall Quickvang, Sparcraft, Nautos and unspecified "Rod Kicker". All solid vangs with a maximum power ratio of 12:1. The TC came to the conclusion the Vang...

Re: Mast base location?

On Zig Zag the base is at least 1" thick (hull #37 built by TPI) at factory holes and new holes ~1" forward. I suggest to move the base to get to 460 mm and then drill new holes in the middle of the slots this will give some flexibility to fine tune the location. BTW did you get a longer h...

Re: Replacement Wheel for Helm

All US built boats came standard with a 54" Edson Diamond wheel, no options was available from the factory. This wheel is still readily available, therefore no class legal substitutions are allowed for US built boats. French built boats, as far as we can tell, came with several options from the...

Re: Removing the center table

After a thorough review, the Technical Committee unanimously decided NOT to recommend to the Executive Board a rule change that would add the saloon table as optional equipment (rule 4.3.12). Accordingly, for J/109 Class or Fleet sanctioned events, the saloon table MUST be installed in its original ...

Re: Removing the center table

The Technical Committee was asked to evaluate if the salon table should be listed as optional equipment, rule 4.3.12. Our opinion is that removing the table do not change the performance of the j/109, it is more a perception of convenience/better access or lack of support if removed. Input from owne...

Vang controls

At the annual meeting this came up as a safety related question. The standard vang is a 12:1 system; a 3:1 internal wire or Spectra tackle in series with an external 4:1 block and rope tackle with a cam cleat. Rule 4.3.9 allow this single ended control line to be led back to the cockpit. From a safe...

Re: replacing Mk3 furler with carbo foil

Eliminating the furler is a performance issue and would force all boats to remove it for OD racing, therefore not allowed.

Re: Clutch replacements

I agree with Bill, we have used the Constrictors the last 3 seasons without any problems. We also switched to the ceramic cams in the stock clutches.
As far as class rules, it is no problem to switch to a XTS in series with the factory clutches, but why?

Re: Genoa Track

Re: Mast base location?

The 460mm is from mast to bulkhead, most boats had to drill new holes for the mast base to get to 460mm. The headstay length of 150mm from base length seem too much, the adjustment of the Harken furler is max 3 inches. Some boats adjust the length of the headstay +/- 0.5 inches depending on wind con...
