What about making carbon fiber rod holders?
That would be a save a few pounds.

I'd love to see it. [email protected]$$. That sounds far-fetched though, even for a cat, at almost 12000 pounds with twin 350s.

We are not expecting either 60 mph or 12,000 lbs. :-)

So I guess that means it will be lighter and faster??

I was heading down the smooth asphalt of I795 towards Beaufort last Friday and it hit me; I can't even begin to imagine what it's like to do 70 MPH in the open water. Maybe one day, I'll be able to get a little closer to that top end speed and appreciate it!

In a cat behind a windshield it is awesome! I used to have an Eliminator that went 90, slow compared to most big cats but it was still a lot of fun. My normal cruising speed was 70.

As you can tell, I am a big economy freak. But for the life of me, I just cant see this big ass boat that is 12' wide and 39' long running much over 60mph with the engines spec'd. Perhaps there is is secret sauce we don't know about.. I love the build and the carbon fiber composites should yield a very light and stiff boat. Windage seems to be your biggest obstacle...

Best of luck,
MPG

Default Fish boxes

This is the mould for the two rear insulated fish boxes
they are approximately 220 gallon each
Notice the sloped bottom to aid draining / clean up
they will have 4" + of foam insulation encapsulating them

A Piper Cub "Airplane" will gross out at 1221 lbs and cruises at 75 mph on 40 hp. That is 30 lbs. / hp.

If we gross 10,000 lbs. and have 700 hp, that is about 15 lbs/ hp. Whooo Hooo.
Maybe a little wind in the right place won't be a bad thing.

My Dad had every issue of Popular Science from 1920 on when I grew up, and I remember pouring though them and reading about the Robertson Waterplane in a 1930 issue.

https://youtu.be/oSgn6jvZnrM

The Sea gull also achieved 70 mph. Not bad for 60 hp. We have a couple of Evinrude 4-60's like were used for both boats stashed away and could have built something like that for Ray. ELCO 4-60(Evinrude Light Twin Outboard)

Something about needing a head in the console, Rod Holders. Raymarine glass screens, 1 K transducers and room for 12 etc.nixed that idea.

The main reason is that it is a cat hull, then with a great bottom design and light weight it will perform much better than a comparably sized V hull. No secret, just riding on a cushion of air.

Just a thought, but it might be nice to have the bottoms square instead of rounded, that way when you need to stuff it full of stuff for a trip, it is easier to pack things into. 4" of foam is fantastic, I wish the idiot that built my boat did that!

Will the lids be 4" thick also?

Like a Boston Whaler, the inside shape does not necessarily reflect the outer hull in the 39, which is planar.

In fact the smaller cats did have rounded hull lines. I think the rounded hull lines make a better sea boat. I had evidence of this with my 22' Compmillennia cat when I had six Marines from Va Beach aboard observing surf trials of a small air drop rescue boat we built. A Big one caught me looking towards the demo. It was breaking as high as our heads and we surfed sideways for several hundred feet until we could see the sandy bottom and get a good look at some Bikini cleavage! Took nary a drop of water aboard. Hoo Raaah

Its a good point regarding having a flat bottom compartment to accommodate storage. Principally the insulated fish box is the cross section it is to facilitate getting good foam under the box. Ray and I discussed some options for mold plants to capture 5 gallon buckets, and now that I think about it we could also make a provision for shelf. Having a shelf, and dividers, but with the drainage below keeps things airy and dry.The whole area above the fish box is a 2 3/8" cored laminate with an R value of 14.

Ray has had more boats than I have had T shirts and we discuss all of the options and make a decision.

I would want rounded bottoms on the fishboxes too. It might be ok to make them flat if they are angled for drainage, but otherwise youre going to have some flat spots where it wont drain completely.
Going to have to have a good insulated lid for that box too to take advantage of the 4" foam around it.
