Below is the inspection list the Technical Committee has developed for the 2018 North American Championship. The list is a tool for owners to prepare boats for inspection and at the event check boats for rule compliance. Sails must be registered in advance on the event sail tag registration form. Th...

Specifications J109 Engine With the boats in our class getting up in age, 15 + years, it will be more common owners need to face the issue of rebuild or replace the engine. The Technical Committee has investigated engine specifications and type of engines used during the years of production. The spe...

Brooke, Thanks for posting this info!
The upgrade is a safety issue and absolutely Class Legal. Other custom solutions for heavy duty versions of this connecting piece are also Class Legal as long as the function of the Block/Swivel assembly is not changed.

Based on the comment from Kerry and others it seems some boats have backstays that are too long for the standard J109 size 10 adjuster from Sailtec. In order to fit the overall length and stroke of the adjuster it is legal to shorten the backstay as well as adding toggles if too short. To avoid a si...

Interpretation of rule 5.7 by the Technical Committee Rule as written 5.7 For J/109 Class or fleet sanctioned one design racing, purchases shall not exceed (a) two mainsails, jibs, and spinnakers in the first year of ownership (b) plus one mainsail, one jib, and one spinnaker during any subsequent c...

I agree with the statements made by Bill, perhaps with the following additional comments. If you damage one of the 5 declared sails beyond repair you can ask the Class Measurer for permission to replace it with another registered and approved sail, that sail must then be used for rest of the regatta...

I was asked if a track could be mounted on the cabin top for an adjustable in-hauler lead. This is not allowed based on the only allowed additional tracks are unused genoa tracks (4.3.4) After the implementation of in-haulers, 4.3.5 will apply to barber hauling as well as in-hauling using U-bolts or...

The traveller cleat support is a SS tube with 5/16 or M8 threads at both ends. On the way to NA last year the top bolt pulled out by completely stripping the threads and the track started to flex up to an 1". In Newport we tried to fix it but to get to the bottom bolt you have to remove all hea...

As the Class Measurer I will be at Block to measure boats, unfortunately we have crew conflicts and can not race our own boat.
I will be available to crew the entire regatta, will do anything but foredeck (trust me you do not want me on foredeck!).Will tip the scale at about 210.

We had our first 5+ hour delivery over the weekend. The new elbow performs very well. The volume of cooling water is significantly larger, absolutely no black smoke and the engine runs much smoother and revs easier. This is a trip we make several times a year and in the past we have used just over 5...

The process to change/amend our Class Rules can be found in the J/109 Class Association Constitution item 7.0

No the primary rope clutches are specified as Spinlock XTS, two doubles on each side. These clutches are still readily available as well as the service kits for them. The hardest or most time consuming issue replacing the cam assemblies is to remove/install the headliners in the head and/or aft cabi...

This is the checklist that will be used for this years Nationals at Block Island. Special attention is needed to bring all boats into compliance with the 66" maximum extension of the sprit, this will be checked with a pass/fail tool. For boats from NJ, LIS and S NE one excellent opportunity to ...

With the average age of the boats in our class now exceeding 10 years the need to replace worn or broken original equipment is increasing. To help owners keep the boats safe and competive and at the same time maintaining strict One Design Specification the Technical Committee with help of J/Boats ha...

This past season I had two independent Yanmar Mechanics suggesting the Exhaust Elbow should be replaced, stating 12 to 15 years of service is the limit. Our engine was commissioned early 2003 and would fall in that range. Since the engine is running at 3200 rpm without smoke or overheating I elected...
