Great write up. Thanks for posting that

devinfox

I’m very sorry to hear about your father. That’s a terrible loss.
I spent most of boating life in the upper keys, Jupiter area and Bahamas so I’m very curious about your draft. Of course fuel number are always a crowd favorite too. Great job on the build btw, impressive work.

Happy 4th of July!

devinfox

Hey Rick, any updates? I hope you've just been too busy fishing...

devinfox

Hey Rick,

Did you have a chance to check your draft depth? Were you able to run your AC on your trip down? I love the idea of the 12v AC, I hope it works great as I'd like to copy it in some fashion one day.

devinfox

Need some pictures!!

devinfox

That is some damn good looking work sir. Any updates on her?

devinfox

On the topic of old posts, I think the thing that I was sad to find was dead photo links. I saw many old posts describing things I was salivating to see followed by a “no image available” icon. I’m sure due in part to photobucket being a greasy whore. In any case, Bob Higgins has emailed me a bunch ...

devinfox

BTW, not totally dead I think! This thing is badass!!!

That’s pretty dang exciting!

devinfox

Pablo, that sounds like a bad idea. I am not an expert, but turbulence problems come to mind. Maybe that’s common practice, but it’s not something I’ve seen.

devinfox

Any progress with this boat? Would love to see pics if so.

35B is a very nice boat. I don’t know if Cummins 6CTA 450 would fit, if not 6.7QSB’s would be sweet. Check out Seamaster marine If budget is a concern, he sells rebuilt Cummins motors in Palm Beach County FL. Both 6bta and 6CTA. I was quoted 80k for a pair of recon 5.9qsb + gears from Seaboard and $...

Bob, I found lots of posts but had old links to pics I think. Has been a little while since I last looked, I spent a sleepless night trying to comb through all your posts searching just your name as an advanced search query. Lots of good stuff though. Carl, that’s an excellent descriptions, my brain...

devinfox

Bob, I’ve searched and searched for pics of your exhaust and engine beds, mounts etc. I want to copy your engine placement (fore/aft) and prop shaft angles if I can. I have seen your exhaust elbow /outboard stringer exhaust pics but can’t find any of how you got your motors so low and close to the h...

The 210’s might be slower on the 28 though. Before I bought my boat I was looking at another 28 with 210 volvos. I remember that boat’s cruising speed was in the 19-20 knot range. I understand you do more than that.[/quote] The Cummins 210's are heavy and big for a 28 in my opinion. Now the Cummins ...

devinfox

Not speaking specifically to any Bertram experience, but on the days that you can it sure is nice to be able to pin it and scoot. For me personally, the boat I bought came with 2 6bta 315/330 engines and mg5050a 1.5:1 gears that the previous owner had gotten out of a 31 Tiara and planned to swap but...

My father and his buddy have a 34’ pursuit center console in Islamorada and while it is a nice boat you cannot run in any kind of crap. It’s only good in well spaced rollers or maybe 2’ seas? Anything over which is very often it is a miserable slog and can’t keep it in a slow plane. It either wants ...

devinfox

Thanks for talking me off the ledge fellas. I’m the type that can’t leave well enough alone. That being said, I’m using the motors I have (315s) I would really like to move weight around and lower shaft angle, I don’t know if I’ll go to the lengths mr lico did but I guess I will see how achievable i...

devinfox

Carl and Tony, Your points are well taken and appreciated. Plan is set the boat up for 1.5:1 and 315hp 6Bs. I talked with guys from a couple rebuilders and they asked why I was thinking about ditching my current motors, which made me rethink it. Both said motors could be rebuilt and some new parts b...

devinfox

Ok, played around with the prop calculator https://www.vicprop.com/planing_size.php lowering the rpm raises the torque rating on the calculator and calls for a larger Diameter prop. I get that a lower rpm motor needs to push more water per rev. But when I changed the ratio to 1.25:1 the wheel size d...

devinfox

Carl, Just a hypothetical. The non aftercooled “ct300” model I would think would be easier to maintain than the CTA and id think would hardly be working to power a 31 Bahia Mar. I am looking at a total gut aft of the cabin bulkhead really (including beds, struts, shaft logs, rudders and deck- and no...

devinfox

I’ve read of cat 3116 and 3208s in 31Bs, even Detroit 453s. Why not a 6CT300 or 6CTA350? 6CT300 with no aftercooler sounds awesome. The weight of the motors I think might help achieve the same head sea ride some people have mentioned with 3208’s and that motor at that power level ought to run foreve...

devinfox

Reading on boatdiesel it sounds like my engines have an RSV governor as well as a nippondenso pump and they will not idle below 750 rpm without surging and or stalling. From what Mr Bob Lico has posted, properly propped it would be way too fast of an idle at that speed, can anyone speak to this?

devinfox

I am planning on replacing the struts and glassing in new shaft logs. Engine beds will need to be new as well, so I figured I would make the changes to reduce shaft angle while I’m at it. Would you suggest reman or rebuilt or new something other than Cummins? Can’t say I really have an allegiance, b...

I’m getting prompted to up my subscription to host photos which makes me want to punch a kitten. It’s only for here that I am hosting them anywhere. Is there a better or cheaper alternative to Photobucket? I’d much rather give money to this site.

devinfox

Damn you work fast! Are you using poly resin for those repairs? Keep it up!

I had a kid about the same time I first posted, I must have been kidding myself that I would be able to work on anything. I decided to take on another smaller project with my father before jumping into the Bertram. We’ve been redoing his 18’5 Maverick Master Angler this summer. In the meantime I hav...

Hello my name is Paul, and I'm the brand new owner of a 31' Bahia Mar 1972 (hard top model), here in Bermuda. It's been a dream of mine from about 1978 to own this boat, and after several "polite" inquiries and attempts over a span of 10yrs or so - they've finally agreed to let me take the helm. I'...

devinfox

Your boat is looking amazing! Did you make that deck or is it a cabrera or similar? That sure is sweet either way!

Who has bronze shaft logs and who has fiberglass and why did you choose them? I have to upgrade and I am looking at a bronze pair from high tide or glassing in shaft tubes. Would love to hear some pros and cons for both. edit: I am looking at G10 epoxy/glass tubes as an alternative to Capt. Pat's me...

Neil, what HP are your motors? They look like 6bt Cummins of some flavor.

Congrats and good luck to you with your project, I own the former Vamos, now named "Bruiser". I completely refitted the boat and have thoroughly enjoyed it. 1 and 1/2 yrs of work was worth it! I'll try to get some pics up. NO WAY! That blows my mind! I love that you’re on here! My dad’s best friend...

Hard top. Just messing around looking at dimensions. Still looks pleasing to my eye. Any opinions?

devinfox

Neil, thanks for posting all of that. You guys have a great looking boat and have does some great work on her. That is setup very nicely. I really like how much shade the top has fore and aft. That is exactly the kind of upper control I would like to do also, just minimal pipework and very small hel...

2 winters ago was a big project year as well as I redid the back deck, building fish boxes and gutter system, once again with help from JP. We began by making a jig up, seeing how big of a box could fit in the glass tech deck we had. Then we cut the hole in the deck and made a gutter system to keep...

Hey Devin this is Neils son, Neil Jr. Just figured out how to post pics without photo bucket. We have had our Bahia Mar for 8 years now and racked up quite a few hours. I have made a lot of changes to her in the past few years and she is getting pretty close to perfect for what we like to do. JP Da...

If you're willing to remove the hard top all together there might be a better solution to meet your needs. I didn't put this hardtop on, but the previous owner (also named Charlie) is on this board regularly and might be able to share more info about where it was made. My hardtop has heavy duty alu...

I put ventilated seats into a set of corbeau's for a jeep, so I don't see why this can't work!

Thank you very much for the info and the offer! Do you have a Bahia Mar? Could you post a picture of her?

I really like how John Cranston’s boat “Cowboy” is set up. I wonder if anyone that has a custom solution on a Bahia Mar could chime in? At the very least I would try to rebuild the windshield frame to resemble a more factory appearance. Currently it has aftermarket windows glassed into way too much ...

Thanks Tony, I agree. My only real gripe aesthetically is the windshield. I'm hoping I can support the top with aluminum pipe in a way that looks nice and allows me to use some isinglass when I need/want it. Another idea is to try to remake the windshield frame and have windows made for it. I've onl...
