Double Trouble - J125 - Preparation for TransPac 2011     (back to showcase home page)

Projects: Carbon crash pads; new Pole-Out system with composite eyes on the pole tube; composite eyes to replace Harken turning blocks for checkstays and spinny sheets; repair cracking bulkheads and add clearcoat carbon chafe strips; replace halyard blocks with custom G10 Padeyes integrated with a deck tie-down system; stack tie-down loops in deck; new composite padeyes for bow netting; emergency rudder system; angled driver platform; carbon companionway and vertical hatches; halyard deflector system for genoa staysail; deck tie-down system for genoa & spinnaker staysails; custom carbon fiber bunks; new Dynex sk78 spinnaker sheets with vectran polyester cover; new back up masthead halyard; vhf antena at masthead; spreader / rig tape job with 3m extruded chafe tape; foulie drying line in bow;

Dragging sails in and out of the boat trashes the bulkheads so we made custom carbon braces that create a smooth surface and protect the surrounding structures.
We made custom soft loops coming out of the deck for lashing down sails to windward. These loops are soft so won't tear foulies of snag on anything. The crew can slide across the deck and not even know they're there. They are completely dry down below and weigh almost nothing. SWL is 650 lbs.
We used composite padeyes to rig the bow netting. This allowed us to install the netting outboard of the toe-rail which makes dragging sails easier. The soft eyes will never rip kites and are very low profile.

We build an emergency rudder system. This is the rudder cassette. The cassette is designed to not put any clamping load on the trailing edge of the rudder blade.
We build the carbon and g10 gudgeons custom to the angled transom.
The carbon blade can be clamped at any depth depending on wind and sea state.  We build an angled platform for the driver. It has two settings for 10 and 20 degrees of heel. We covered it with strips of non-skid tape. 

Two internal G10 rods slide down to lock the hinging second level.

The hatch can be locked or unlocked from either inside or outside. 

I replaced the Harken turning blocks with a custom composite padeye. The outboard eye has a ferrule to lead the checkstay to the cabin-top winch; the inboard  eye is for attaching a turning block to send the spin sheet to the high-side winch.
This is how the composite padeyes look from underneath. We pulled a molded piece off the deck, creating a perfect and incredibly strong joint. It's also completely dry.
Dragging sails in and out kept trashing the companionway entrance. We added a carbon chafe strip and never had a problem since
The spinnaker sheet blocks in the back of the boat are notorious for  tearing up the deck and hull. We built these custom crash pads which elegantly solve that problem. These are now being replaced with composite eyes.

The padeyes for the halyard blocks at the base of the mast were another problem spot. The deck was never cored before installation, and crushed as a result. Here we've removed the hardware and filled the holes and will now replace with composite eyes.
Here you can see, from underneath, how the backing plate for the padeyes had cracked right through the bottom skin of the deck. We layed up carbon over this area to strengthen the bottom skin.  The aluminum backing plate shows signs of sxtensive leaks and corrosion. Not surprising considering the loads and the usual issues with dissimilar metals in the marine environment.  The composite padeyes for the spinnaker sheets. We used a vacuum bag to make the part as light as possible.

Same padeyes, now installed in the boat. Unlike a metal washer, our part loads up on a much larger section of both deck and hull. Same padeye, as seen from a different angle Same padeye, as seen from above decks.
