Zero Cavity Pics

Bruce · Post by **Bruce** » Jun 6th, '07, 20:36

Here is some eye candy of "Zero Cavity"

Did the final tweaking and sea trial today and I got 33.8 knots @ 3950 rpm with full fuel/240 gallons.

Instrument display pic is the Ray Marine e-120 interfaced to the Teleflex can buss system. I setup a full page display as an option for twin engine.

There is also a Teleflex display on a pull out panel on the bridge if you want to use the Ray unit on a full page GPS map or depth.

Additional is a Teleflex display in the stb engine room so you can monitor port and stb vitals while working on them without out having to jump to the bridge.

Both Teleflex displays are setup to show twin engine.

My part in this project was engine systems, controls, wiring and computers, startup, sea trials and tweaking various systems through out. Gen start up and load check.

Thats a great looking job............I'd be upset to see any fish blood or slime on that boat anywhere.

Simply beautiful

All these nice looking 31's sure make me feel like I need to go back to the drawing board. Great Job!

Really nice, the soft gauges might take some getting used to though. Bruce, where is the main panel you show located? Great job!

Nice clean job.

The panel looks like it's on the rope locker door. Is there an enclosure behind it?

Is this a FBC with the head removed, or a SF with a bulkhead added?

Where's the charger?

CaptPatrick · Post by **CaptPatrick** » Jun 7th, '07, 07:22

Scott,

The panel is in the overhead, forward and center to the inside of the bridge facing. Regino Cabrera & crew did the vast majority of the work in Miami over about a 2 year span. The housing for the panel is glassed in & the overhead is raised about 3" over stock height.

Mike,

Gerry's "Zero Cavity" is a FBC & the head was moved to the V-bert configuration.

Br,

Patrick

Very nice indeed, inspiring. I'm going home and break out the sander.

Vince Luciani · Post by **Vince Luciani** » Jun 7th, '07, 08:19

Wow! It truly is inspiring. Being in the middle of my own project, I have a great appreciation for the amount of hard work and skills (and time & money) needed to complete a project like that.

Good job Bruce!

Gerry,

Nice looking boat! You should be proud.

How has the baby Bert been treating you?

Nic,

The wheels are 19x23 four blade Nibrils.

Capt Pat,

HP, Trans ratio, and cruise speed would be helpful as well.

I am trying to compile a listing of repower results

Mikey · Post by **Mikey** » Jun 7th, '07, 10:09

Gulp! Sure makes me jealous. Fabulous work.
Congrats, Bruce and to the Cabrera gang.
Whew!

Bruce,

Are the cast, 90 degree, jacketed, water injection elbows Yanmar pieces?

Eddy G · Post by **Eddy G** » Jun 7th, '07, 12:55

Scot: The cast mixing elbows come from Yanmar with the engines and are normally attached directly to the turbo. Many applications require a custom made dry exhaust extension to gain the needed height above the waterline.

Gerry, you make Dick Bertram smile.

Bruce · Post by **Bruce** » Jun 7th, '07, 17:14

Props also have a medium cup.

Yanmar 6LP/315hp, 2:1 gear boxes.

Cruise speed can be anything up to 200 off the top.

24knots@3000 rpm
29knots@3600 rpm

Elbows are factory part.

Pulled the boat this AM but not before taking Tony, my shop mate out for a ride.
He's missed my last two 31 refits and is the only guy I know with arms big enough to have a 46' Bertram tatoo'd on his bicept with great detail.

Great Job! and take a look at the fly bridge "roof"of the boat named No Respirar at the boat pics area....owner Cesar Rivera.....he designed it for his and it looks sleek......almost like the original one.....

What is her cruse speed & fuel consumption ?

Installing a tower ?

Gary,
Speeds are posted above.

No tower.

6LP's average 1 to 1.5 gal/mile at cruise.

Thanks to everybody for your nice coments ! Happy to share my project on this board for the past 2.5 years.

Beautiful! How did they do the front windows? Are they fiberglass frames?

CaptPatrick · Post by **CaptPatrick** » Jun 12th, '07, 09:40

John,

I totally encased the original aluminum frames with ~3/16" of fiberglass layup. Each of the three sections were done individually leaving the designed slip joint for re-assembly.

Revels were made with PVC Foam Board & were glassed in so that window glass and acrylic corners would be glazed in from the inside. Both the glass and acrylic were glazed in before taking the units back to Cabrera in Miami for installation on the boat. They were fiberglassed in place, faired & gelcoated for a seamless installation.

Interior flange moldings were fabricated and fitted in fiberglass sheet stock.

For the blow by blow progression see: Glassing Over Bertram 31' Front Aluminum Window Frames

Would I do this again? Probably not... Way too much time and agrivation.

Br,

Patrick

Rawleigh · Post by **Rawleigh** » Jun 12th, '07, 10:06

I think you were working on those when I stopped by your shop a couple of years ago. They did look complicated, but beautifully crafted.

Craig Mac · Post by **Craig Mac** » Jun 12th, '07, 10:17

Capt Pat,

How many hours did this take?

How hard would it be to fabricate in stainless? I know the Bertram Riva 25's had stainless frames.

John Jackson · Post by **John Jackson** » Jun 12th, '07, 10:28

Capt. Patrick:

Wow! This just proves that when there is a will there is a way! How the heck did you come up with the game plan for that project? How many hours did it take? Is there any chance of the fiberglass delaminating from the aluminum? Any interest in doing another one?

I like the way the slightly larger frames look on the boat. I have redone my whole boat, but the windows, while I doctored them up to a point of acceptability, are not on a par with the rest of the boat. I had a welder fill in the holes on the curved window outside rims and that part came out pretty good. I bolted it from the outside, and the screw heads donâ€™t really offend me, although the clean t-bolt from the inside way does look much better. To disguise the condition of the windows on the Hound I had my canvas guy make a front windshield cover that is clear with white over the frames and from a little distance it makes it look like the frames are a little fatter and I think it improves the appearance a little. Plus it has stopped all the leaks. Maybe I will take a crack at doing what you did over the winter. I will try and take some pictures of my "quick fix" and send it to you.

PS. Are you going to Atlantic City?
