Shrouds & Stays

There are 2 types of turnbuckles found on shrouds at the club.  These are:

1. Series 200 Open Body - the new system - identified by the turnbuckle which is an open body with female threads. 
2. Navtec Series 500 - the old system - identified by the joining turnbuckle which is a threaded rod.

When ordering replacement shrouds, please update to the new system with the Series 200 Open Body.  Do not order any more shrouds with the Navtec turnbuckles.

Stanchions Bases & Tubes

Stanchion bases and tubes have undergone many improvements and changes over the years.

For the bases, there is a new style (identified by 1 brace) and an old style (identified by 2 braces).  Because of the deck angle, there is a separate base for both the fore and aft stanchion.  With the new style, the forward stanchion base provides a 10 degree angle and the aft stanchion base provides a 15 degree angle (the old style was slightly different).

For stanchion tubes, many race J/24s are using 1 lifeline and a shorter height but we are using the standard system of 2 lifelines and the full stanchion height.  Order stanchions from Waterline systems. I had to ask and make sure they had a "nun" shaped head and two holes for lifelines. They have to drill and install a wear collar so I was encouraged to order a batch (12 I think, perhaps 10). They they can set up a jig etc.

Stanchion Bases

• Stanchion Base (fore or aft) order from Waterline systems 401-682-1661

• Stanchion backing plate

• 4 Cap Screws – 18-8 Stainless Steel Hex Head, ¼”-20, 1 ½”

Jib/Genoa Cars & Tracks

When installing any thru-deck fitting on jib car tracks, sufficient 3M 101 must be used.  Failure to use enough caulking can lead to water getting into deck, one of the biggest problems which could affect a J/24.

• Jib Track, Schaefer #4042 - #196576 - get new info from Ken

• End Stop for Track (silver) Schaefer #74-35-G -#196709

Halyard Turning Block Padeye

When installing, extra care must be taken when drilling holes through the deck.  These holes must be drilled perfectly straight.  Failure to do so will mean that the backing plate will not work.  Before installing padeyes, double check the length of the cap screws.  These screws should be the minimum length to allow the installation of the nut on the bottom side but not stick out beyond the nut once tightened.

Rudder

The spacing and angle of the rudder gudgeons is unique to every boat.  When removing more than one rudder at the same time, it is essential the rudders are numbered and that the same rudder is reinstalled on the same boat.  If the rudder is not put back on the correct boat, the gudgeons will not line up perfectly and there will be friction, making the boat more difficult to steer.  Racing sailors require the rudder to be totally free moving without any friction in order to be able to feel the helm of the boat.  If a rudder has friction, the transom gudgeons should first be checked for possibly being bent.  If they are straight, the gudgeons should be completely removed from the rudder and connected to the boat with the pintels.  Then fill the old rudder gudgeon holes with epoxy.  Sand & paint.  The hang rudder in gudgeons on stern, drill new holes and install.

Gudgeons on Rudder

There are 2 gudgeons on the rudder, upper and lower.  The upper is shorter than the lower.

• Heavy Duty Rudder Gudgeon Upper (Schaeffer #81-47) - Port Supply #252205 

• Heavy Duty Rudder Gudgeon Lower (Schaeffer #81-48) - Port Supply #252213

• 1/4 x 20, 2" bolts

• 1/4 x 20 locknuts

• no washers needed

• use white 3M 101 sealant

Note: The lower gudgeons break on the boats occasionally.  There is no way to predict when a gudgeon will break except by inspection.  Occasionally, but not always, it is possible to identify a tiny crack in the gudgeon before it breaks.  This can only be done while the boat is out of water so every spring before launching, all lower gudgeons should be carefully inspected.

Gudgeons on Transom

Gudgeon assembly for transom of boat (4 total, 2 for upper pintel and two for lower pintel)

• Heavy Duty Transom Gudgeon (Schaeffer #81-46)- Port Supply #252221

• 1/4 x 20, 2 1/4" bolts

• 1/4 x 7/8 in diameter washers

• 1/4 x 20 lock nuts

• Install bolts with white 3M 101 sealant

Notes: The gudgeons on the transom occasionally bend when a gudgeon on the rudder brakes (usually the lower gudgeon) and the rudder is still used even though attached by only one pintel.  This sometimes caused the upper gudgeons on the transom to be bent out of alignment.  You will notice resistance when inserting the pintel or when steering the boat.  If a transom gudgeon is bent, it must be replaced to ensure smooth operation of the rudder.

Sound Producing Device

Over many years, the club has tried to provide a variety of horns on the boats.  However, all types of horns have proven a consistent maintenance issue, either disappearing or breaking.  We are required to provide a sound producing device on the boat and this should be used when exiting the marina.  Beginning in 2005, we are changing over our system to install a storm whistle which will be permanently mounted to the aft pulpit.  This whistle will produce a loud sound sufficient for warning traffic when departing North Cove and for signaling out on the water.  Skippers are also encouraged to bring their own personal horns (just like they bring their own VHFs) when sailing if they wish a more traditional sound producing device.
