We make carbon fiber steps, and I think Ray is going to need one to reach the bottom of his fish box's.

I am sure a carbon fiber shovel is possible. :-)

I'd love to see one of your boats with just a clear polished finish that showed all of the fiber work.

Save that hundred pounds

unfortunately I don't think there is resin that is UV stabilized enough to take direct sunlight as would experience on a boat.

We built a triple outboard engine 42' in perhaps 1996, so that is almost 20 years ago. It was a cored epoxy one off and we laminated a carbon fiber cloth over the hull sides. It was clear coated and a few years ago I called on the guy as I was curious how the clear coat held up.

He said just fine, even though it was berthed all that time in Fort Lauderdale, and was used regularly and continuously. It had a covered in the water berth, so its not laying out in the sun.

Clear carbon is a premium product. I cannot imagine you leave your carbon fiber fishing poles laying about either, although carbon fiber sailboat masts we and others have done would get continuous exposure and get five or six years life before re-coating.

I am sure we will do a clear carbon hull side one sooner or later. My original Egret boats advertising guy was making noise about doing one. Right now you lift a hatch and you can see it the clear carbon laminate. Kinda like flashing your knickers.

Nice. I guess clear coat helps for sure. My concern would be of the resin yellowing or clouding up.

Fish box's "box" ticked off. I am really pleased how they came out. We went to the expense of building a mold for them and the results were worth it. Initially we were all about round corners and cambered bottom, but in retrospect I decided to add a slight landing flat to keep a couple 5 gallon buckets from scuttling to the back of an empty box. There are no fittings , impossible to service which could leak into the foam. The drain plumbing is all bonded composite.

I am very interested. I would like to see this build in great detail with a lot of photos. My son wants one...............

I love how clean the CF looks.
Wish I could build a clean mold and replace some of my cheap-looking plastic hatch lids with carbon fiber ones......the black would really set off my boat!

Curious. Are you going to use Li-ion battery's for the weight savings?

I spent considerable time investigating L I battery's .
I could not get comfortable with them although I think their the future
I believe they need More exposure in the boating world.

I think the bigger issue with lithiums would be alternator charging them properly.

We will be going with AGM's. I have been impressed with the one I have in my truck for the last two years. That may not sound like much of a recommendation, but I took it from my VW Diesel after two years service. That may not sound like much of a recommendation either, but I drove the car into a puddle on a back road between Bolivia and Boiling Springs N.C. , and the puddle was a sink hole 7 feet deep. The only part of the car left above the water was enough of the trunk to sit on for two hours before the the fire department pulled us out. That battery was still cranking out amps because the Jetta sounded like an excited R2-D2 in Star Wars until I disconnected the battery. That is a good enough recommendation for me. :-)

The console is a very busy area of the Cat. We are striving to build a "Clean Machine"

Fitting the T -Top legs to the console. Should be about as as sanitary an installation as possible, at least after vacuuming up the Carbon Fiber dust!

T-Top getting vacuum laminated laminated last week.
Higher density core in selected areas. Carbon fiber face skins with high fiber to epoxy resin rations.

Every pound of weight saved in the composite structure while maintaining strength is important for a variety of reasons.

Fuel economy and speed are achieved in inverse proportion to weight.
Lighter = Faster, Lighter = less fuel. You also pay up front buying hp to achieve your desired performance, Lighter = Less Horse Power required. Perhaps even one or two less engines. The payback is forever.

Less weight, particularly high up generates less inertia. Being a sailboat racer in my secret life we learned that a long time ago. As you punch into that sea, and the hull wants to slow down, but the weight up high wants to keep going, driving the bow down further into the wave. Think about having a Kid on your shoulders and tripping, and the extra effort to recover from falling on your face.

Less weight is beneficial in other areas too. Like in hatches, if you drop one on your fingers or toes!!

Great analogy, helps put it in perspective.

The top is coming along. Its a one off, meaning not built from a production mold. Properly designed and built the one-off composite parts can be substantially lighter than most production parts, but the finish work is more labor. In that this is the first 39, it is an acceptable cost . A T top that uses bricks in its construction may be a first.

I left my pulse arc welder for aluminum piping in Miami, but to save overall build time we are pre - bending the pipe to a mock up, and what little welding we need to do will take place on the bench.

Aluminum piping is an aesthetic element for most owners. We are working to meet Rays expectation. While I am a minimalist, Ray appreciates some sexy curves. We fabricate aluminum for these legs instead of composite legs for that reason.

Pictured is one of the legs mocked up, and will ship to the pipe bender cut to length as a pattern. I was thinking it closely matches a tail pipe from an F-250, and could have saved some money there!.

Preparing our under deck rigging now.

We are fitting pairs of billet machined high capacity fuel / water separator heads as part of our fuel management system. Its good for 120 gallons an hour and will filter down to 3 microns. Off the shelf fuel filters typically have 1/4" pipe thread ports, or 3/8" at best. We have 1/2". Who cares? With two 107 gallon fuel tanks each side Ray directed us to provide for running both engines from any of the four tanks. Potentially that's 700 hp from one line and we will have a 5/8" fuel line to each transom with minimal restriction, and maximum filtration.

I wrote the check to Mercury last week for a pair of white 350 Verados. Whoa Boy, at that expense the upgrade to the fuel system is a small price to pay.

I know all things relative..and this is a superior build like all your boats..Putting cost a side..This is the proper way to do it.....Its like when I build a house and the plumber asks every time..Jeff, you want a 3/4" or 1" water line.. the answer is the same.

I hate to see the cost of painting those Mercs...I can only guess..LOL

you might consider some stainless fuel filter heads instead of aluminum. The aluminum ones I've had always corrode after a few years to a point where I replace them. Stainless ones, last much much longer
