March 2, 2017

The Technical Committee has received a request to rule on whether it is legal to apply sealing material to the gap between the keel fin and hull surfaces. The request documented the potential boatyard and commissioning costs the practice adds and the conflict this causes with a stated mission of keeping costs reasonable.

The committee has voted that filling the gap between the keel fin and hull surfaces with any material including, but not limited to; silicone, 3M 4000, epoxy, polyester is not allowed.

Alternate Mainsail Pre-Feeder Approved

December 5, 2016

The Technical Committee has approved a Class Rule interpretation request to allow the use of a different mainsail feeder than that provided with the C&C 30 masts. There were reported issues of bolt rope tears when hoisting the mainsail and the approved feeder which has been field tested has been shown to fix that issue.

Description: Custom 3D printer manufactured nylon pre-feeder. Fits in existing bolt holes and is flush to primary track. Provides smoother, tear free hoists and allows positioning of batten receptacle bumper ropes closer to primary bolt rope for smoother shape at inboard ends of full length battens.

We are pleased to announce that Dobbs Davis has been appointed as the Chief Measurer for the C&C 30 Class. Dobbs is one of the most experienced and respected measurers in the US and is intimately involved with the ORC rating rule. He will be measuring all completed boats at the factory prior to departure as well as handling all measurements in the field and onsite for all major class events. We look forward to working with Dobbs at major class events and are excited to have him onboard.

Measurement and Equipment changes update 24 Feb 2016

Moving forward all boats participating in class one-design events will be expected to be in full compliance with the Class Rules. This will include class weight, hull and appendages per Rule AP.1, Sails, deck layout and equipment. We plan to schedule several measurement opportunities prior to the class events in Annapolis and Newport.

Several changes were incorporated to Rule AP.5 and are now included under Rule C.7.2 have been approved, including the following:

• Installation of Removable Lashing Pad eyes (Min load rating 7000 kg) in place of Wichard Pad U-Bolts for the backstay foundation

• Installation of two deflector blocks or fairleads for traveler control lines forward of the tiller on the cockpit floor (see approved location on the updated Rule AP.5)

• Installation of a Harken Diamond padeye for the deck tie down system directly below the existing Diamond padeye on deck aft of the mast partner, along with the installation of a 3/8” diameter eyebolt in the forward-most hole on the keel top plate for the deck tie down system (see manufacturer’s drawing)

• Installation of a deck deflector aft of the halyard clutches (see approved location on the updated Rule AP.5)

• Addition of a Spinlock Rope Clutch, which may be installed in place of the Harken cam cleat for the jib halyard (see approved location on the updated Rule AP.5). This includes removal of the jib halyard constrictor – the internal portion of the halyard lock may be removed as long as the manufacturer-supplied cover plate is left in place on spar.

• Use of a Mast Jack as supplied by the licensed builder – please note the restrictions outlined in Rule G.4.2 (b): the jack shall not be used during racing and the pump must be disconnected and stowed while racing. The pump is not considered part of the fixed equipment for purposes of weighing the boat.

Hydraulic Mast Jack, fall 2015

The hydraulic mast jack is now offered as an option. “As the sailmakers refined the sail shapes for the class, it became obvious that attention to rig tune is a vital part of shifting gears,” says Randy Borges, President of USWatercraft (builders of the C&C 30 OD). “This is not a ‘set-it and forget-it’ rig – teams need to stay on top of tuning to maintain speed in changing conditions. We wanted to keep the playing field as level as possible without taking away the fun of the tuning challenge. Adding a mast jack makes adjustment quicker and easier for everyone to achieve in the short time between races.”

Weight Limit, fall 2015

The class has eliminated the crew weight limit in favor of a minimum crew number. Teams must simply start and finish each race (and series) with the same crew members. “Weight limits unnecessarily complicate an owner’s crew selection, as well as the measurement process,” says Borges. “This allows each team the flexibility to sail with their friends and family, regardless of how much they weigh.
