I was leaning towards the split V but after all things considered went with a somewhat symmetrical V bottom with a pad. This was partly to accommodate the Wilson 41 project. That is what he wanted for his cat's bottom. I accommodated but with our stepped hull feature. My friend Davey Wilson raced offshore from the earliest days and rigged all of my big boats in Miami. Some guys are good for nothing but Davey is often good for 4-5 mph!.

The pad reduces draft with a twin installation. Also it simplifies Quads as they can be equal length legs, as opposed to the split V needing a long and short leg. Both engines will be deep and also be getting clean water. Our mold accommodates a 14' beam for the guys that don't trailer regularly and may also want more length and or quads. If you go to the boat show you see the demand for quads is there.

1400 hp quads with not much more weight is a wee bit mind boggling. Watch out Nor-Tech's!

That was not the mission statement for Rays boat. Quote below, and I would add "a ride like Butter!"

And Construction has commenced !!
Dimensions are 39' long 12' wide beam
She will be powered by 2 of the new Mercury 350 hp Verado's in warm fusion white
Performance goals are a 45 mph cruise at 2 mpg.with a decent fishing load
Expected Top end speeds in the high sixty's she will also plane on one engine
420 gal fuel capacity in 4 tanks
This boat will be built with the best of the technologies that are available, vacuum bagged, infused, temperature cured ,composite, Kevlar, the list goes on.
This is a center console design with a walk thru transom wide enough for a wheel chair to pass thru.Their will be an extended dive platform between the engines , although their will be no engine wells everything flat same level.
Expected weight ready to fish is 11750 lbs with an 18" draft, their will still be 12" of air gap between the water and the top of the tunnel
Dual 400 gal fish boxes,large coffin box to accommodate twin lounger's to keep the girls happy
Flip down single seats along transom, Three across Llebroc seating at the helm
Two flip down seats forward desighned for 2 people each
Raised casting platform approx. 12" above sole 12" plus wide gunnels
bow area approx. 42"deep x 10' wide big enough to throw a cast net from.actually 2 at a time
mounted under deck EZ Anchor puller winch with free fall completely hidden with 900 + feet of dyneema 5/16 anchor line,25' stainless chain and a Rocna anchor
This hull design is a stepped, air entrapment, pad bottom catamaran
Full Raymarine system 2 GS165 glass screens cp 370 and cp100 auto pilot mercury 7" vessel view 12 kw open array separate key pad for the touch screens 52" curved light bar all LED lighting 30-40 rod holders and at least 20 cup holders mite add more
its getting late gotta save some for the next post Cya
This is a screen shot early in the development. Not exactly what we ended up with, as there were a hundred tweaks since then, but you get our drift. :-)

Jim - Real sorry for your families' recent two losses.


Too bad this boat won't be at any boat shows because it is really interesting .
Additionally ,it seems to have many designs that are not currently on any other boat.

In any event - hope to see one in person one day as it seems to be the very definition of a "one off fully custom boat " or maybe it should be referred to as a "bespoke boat"?

And you might be referred to as "The Custom Boat Tailor ".

I do like the fact that with the quad installation the motors will have equal length legs...the only thing I'd change is...why have 1400hp when you can have 1600hp.. http://www.mercuryracing.com/outboar...race-offshore/

Well, there are times when Ray is thinking "ready to wear" would have got him back on the water sooner. Custom to his specification is a journey.

I got an email from an old customer that bought the first prototype Egret 29 center console I built in 1996. After 18 years he just down sized and sold it for what he originally paid for it. Lets see.... look for Ray's 39 to be back on the market no sooner than 2034.

I am suffering some anguish as we outfit the boat to his requirements though. I just weighed a sub woofer and a speaker to the kick ass sound system.

One sub woofer weighs the same as three 19" x 43" carbon fiber cockpit sole hatches.

All those zeros are not the weight. That is my scale saying Ow ow ow. ow, as it was maxed out from the weight of one speaker.

I would imagine having the same length motors would equal less barking.

Sow how much will 4 subs and 8 speakers, associated amps, extra batteries, and wiring cost in terms of mpg and mph?

You know that one sub in a properly designed enclosure could put out more bass than several just stuck where they fit. Wondering if you could save any weight doing that?

Can't wait to see this boat in person.

I am not considering the weight of the batteries, as we planned for them in the original weight estimate. There will be 2 isolated starting and two dedicated house group 31 AGM's. Well, we bumped the starting batteries from Group 27's because of the Verado's electrical demands. That's an extra 10 lbs.

My friend Dan Upton ran his 34' Donzi SKA boat with twin 300 Verados on only two batteries total. I was very impressed. A cappella? or maybe he hummed.

So to answer the question, the kick ass stereo costs .4396 mph top speed @ THT displacement, or .3151 mph at fishing displacement.

I thought cup holders were the most important. Makes you go fast.

how about headphones...light, loud, and low amp draw. Bluetooth and waterproof.
Looks like I need to time another visit before she's gone.
Progress is looking good.

LOL thanks Jim! Sounds like it is worth the extra weight to me!

Jeff, why do I hear the Bad Boys theme song ringing in my head?

"When you were eight and you had bad traits
You go to school and you learn the golden rule"

The last boat I built in Miami before before moving to North Carolina had 4 engines and 1400 hp.

Oh yea, that was 1400 hp each engine. We can be as "Bad" as you wanna be. :-)

Suggestion to lose 65 lbs ?
I have a Formula 400ss . this is a 18000lb cruiser . formula wires two group 31 batteries in parallel for the house battery and ties one of the engines to it . the other has a dedicated 31 for it's self . now this boat has 2 TV's stereo, 2amps , Hugh refrigerator , vacuum flush toilet , etc. significantly more electrical demand then my center console . even with being on anchor all night we have never depleted the house batteries down far enough were they wouldn't start the engine . And were talking a big Volvo diesel engine ( probably double the amps required to start any outboard ) .

so even if for some reason he did drain them all the way down , you always have the 2nd engines dedicated 31 starting battery . start it , parallel switch , done.

you just saved 65lbs.

We can not elect to have anything but a dedicated AGM battery for each Verado per Mercury. Verado's are very dependent on voltage and amps because fly by wire steering, throttle, trim and auto pilot pump run off the engine batteries. The AGM holds their charge better than a flooded battery if the boat is stored because if you have a voltage drop it triggers false alarms.

An AGM Group 24 meets the minimum requirements for the Verados so a group 27 gives a margin. I like my engines to start every time. Engine batteries are dedicated to starting. No dockside bait wells or sand bar stereo's running from the electrical source that makes you go!

The house batteries will be two group 31's with room for more if needed!

I mentioned Group 31 starting batteries previously because that may be a holdover when we built short handed racing sailboats. The charging systems we had then required same size batteries. Those boats would sail trans Atlantic and round the World with just two 8D's.

All this becomes a rather mute point because we will have a substantial "state of the art", on board charger. I can hear the batteries now. "Ray loves me, ........He loves me........"

There are quite a few more Navigation and fish finding function capabilities displayed than might be imagined. Gee, give the fish a chance.

On the other hand, for $1500 you can buy a nice German sextant with Zeiss optics, HO-249 sight reduction tables and good time piece which took me 7,000 miles, but I never caught a fish.

Where does that sextant plug in and can you receive satellite information on it?

Good questions. Also, how do you reboot it when it freezes?

The sextant receives sun, star, moon and planet information. Satellite position you have to get from the CIA. My buddy Cal Connell (Rybo Runner and step boat pioneer) was an air Navigator for Tyrone Power who joined the U.S. Marines and was a pilot flying supplies into, and wounded Marines out of, Iwo Jima and Okinawa. Imagine flying at 350 kts over the Pacific day and night with the only way to get a fix before you ran out of gas was by bubble sextant. Its not like an RDF signal was broadcast in Wartime.

We picked up 280 lbs of AGM batteries from Greenville Tuesday to power the sparky bits. Actually My wife picked them up for me as she had business there. That's more than twice what she weighs. Ask me how well that went after she came back.

You said to ask...
