Reverso Boat Design

[cstevens]

Hi,

I would like your thoughts on the Reverso boat design linked here,
here, and here.

I outline my design goals below, and welcome your suggestions. I first have a few questions from the start:

1) Is this design sea-worthy?

2) Is this design within the reach of the amateur builder?

3) Can the design be scaled down to, say, 40' ?

4) Would it be resonable to see this design being built from the "inside out?" i.e.:

a. Build inside skeleton (CNC cut, manual assembly)

b. run strips along hull line

c. Fiberglass inside hull

d. remove inside core

e. Install engines, wiring, etc.

f. Place core in hull

g. cover inside hull w/PVC, layup outside hull

4a. If not, how would one best go about constructing the craft?

5) Does a manufacturing process exist to safely create a seaworthy craft with such large, rectangular windows?

6) Would the center of gravity of this craft be too high to make it practical out to sea?

My goals for the project is to create a live-aboard craft that can serve as a marine office. My business requires extensive travel so I would think that the craft would be sailed for about 6 months out of the year.

I am new to the marine world and as such can call only on my extensive technical experience to draw from. I live in the Pacific Northwest so marine travel isn't foreign to me but traveling at sea for extended periods is definately outside my of my experience radar.

By the way, many of you probably already know of this software but for those of you who don't know about FREE!Ship, it's worth a look to their web page.

I welcome your input and thanks for reading my post.

Coop - I'd suggest contacting the designer. If he can't, or wont, answer your questions, then shop elsewhere. All the queries you've raised should already have been addressed during the design process. If they haven't then the pretty pictures are just that and nothing more.

Is there a real design or did someone just make a picture?

This method would have ZERO reliability for the hull structure.

Google AIREX , and learn foam core construction , a fine strong hull can be hand laid up.

Yoke,

I'm not sure if there are any plans for this craft or not; I wish I had the author's contact information.

I took a stab at creating this craft with FreeShip!. I've attached my initial results.

By the way, I wrote a designer about this design. I asked him specifically--in a business--like tone of course--if the design was 'crazy.' It turns out that, according to this designer, this design is very buildable.

By way of reference, I was concerned about the hull angle. The hull angle is of the "tumblehome" variety seen mostly on catboats. The hull's reverse angle is designed to slice through the wave rather than run over it. This shape is said to reduce noice and lessen wave pounding. More information may be found here.

I'm glad you mentioned this. During my research I found what I thought was a reasonable article describing solid vs. foam core. The article references findings after Katrina; the storm turned out to be a pretty good laboratory for learning building methods that can withstand a pounding and those that were shown inferior.

I do not in any way mean to imply that AIREX is inferior, I just thought that you would be interested. My take on the article: like everything else, foam core hulls need to be done right to work. Here's the article.

Sounds like "old coot with a stick up the arse syndrome" to me. This surveyor is just spouting opinions and trying to present them as gospel. The fact of the matter is that powerboats are frequently poorly built, and often with materials that trade cosmetics for strength (lots of mat and DCPD resins, for example) Foam cores have been used in military craft to improve damage tolerance for a long time, have a look at DIAB's website for more info.

Yeah, I've reasearched foam core technology more in depth. It looks like imperfections with the hulls have more to do with how they're built rather than the technology itself.

I've uploaded a screen image and FreeShip! source file. While I've made good progress, there are some lines (especially in the hull) that I'd like to see if anyone would be interesting in making some suggestions for correcting.

That thing really screams WINDAGE to me.
