We were both standing in the head and it was tremendous. Had a full tub and it even had a couch in there. And I would poke my head outside the head door and say "how the hell did you fit all this in here Bob??" So this is kind of spooky to me that this subject is coming up months later ...if anyone...

They actually automatically add less tab the faster you go. Not sure how it figures it out on what to do, it also automatically corrects the pitch of the boat. There is an automatic Trim option available on regular tabs too. It figures out the Trim the same way your car runs...with a computer. I am...

Carl

Your right Bob, pull the bowl out too! When said person needs to use the facilities, just point to the Cushioned 5 gallon bucket on the deck, which can also double as a wastepaper basket. Problem solved. It's a 30-foot boat, not the QE-2, compromises need to be made. The guy, and yes it is most like...

Carl

If the problem is just the 14 deg angle screwing you up...change it back to zero with a set of 14 deg angled spacers. Kind of like a fairing block to straighten out the deadrise with a through hull transducer.

She's looking great!

Carl

18 days and counting!!!

I am so glad to hear the finish line is only days away.

Carl

then there is that one guy who goes with a Ron Ellis Nibral propeller with its own unique design. Then there is that one guy... Lots of blade area on those Ellis wheels. I remember trying my dads Ellis wheels on my boat with the 440's. Same size and pitch as what I was running, but I could not get ...

Carl

I have not compared bronze & Nibral side by side, but was told by a knowable person that most production is using the same thickness for both--- Maybe some of the higher-tier brands refine the process to take advantage of the superior properties. Same wheel in nibral vs bronze, the advantage of nib...

Carl

What Chris said is exactly why I put them on my boat years ago. When cruising slow the tabs make a dramatic difference. So what's dramatic you ask...well 14 to 17knots is dramatic to me, even 14 to 16 knots is a big difference in speed for the same rpm. I could get someplace faster or if I liked the...

Carl

Impressed I am…but not so much at 400k

Carl

Interesting ideas on the interior... Lots of work went into it, the fit and finish look incredible and the design definitely opens up a tight cabin. Now the "but" part, maybe it is just the pictures But I'm not sure the design flows. Maybe I just need to look closer or revisit. I'm not sure my cabin...

With 300hp Cummins on a 31, you will want Nibral wheels. Which ones I'd leave up to those that really know. Michigan makes lots of different style wheels, but nobody else's. What I'm saying, walking into a Dodge dealership, expect them to recommend a Dodge. Acme is another jump up in price, but you'...

Carl

For the sake of argument, with all other variables being the same, is it possible that bronze would be 20% less efficient? I think not... "with all other variables being the same" That is where you are having an issue with the comparison of Nibral to Bronze. All other things are not equal, you are ...

Carl

Question two is.. The keel looks pretty lumpy. Im assuming this is from years of blocking. Is this normal? Will a concave hump in the keel act like rocker in the running surface? Btw i had the guy that delivered it, get weighed loaded and empty so i could know what the boat weighed. 10,320 lbs Weig...

Carl

What a shame to have to put a deck over that.

FDNY rolled 4 times in 24 hours today for lithium battery fires and 10 people hurt!!! Were the batteries in a Toyota Prius, Tesla, VW, BMW or in an electronic device like an Apple Iphone, Ipad, tablet or laptop? Seems like an awful lot of these batteries are around that are extremely unsafe. Maybe ...

Look like others call them Top Mount, Lee seems to call them Skiff Side Mounts. You've used them so obviously they work for your needs...but mounting on top you only get to utilize two positions up and out. Normally not a problem unless you need to clear a bridge as they will not lay down for cleara...

Carl

...and it’s going to be like starting with a brand new boat. Minus the interior and exterior cosmetics. Priorities- - Does one buy a new boat to use OR to sit at a dock and look good If in a position to aquire both all the better, but if a choice of one or the other...without spending outside what ...

My understanding is the quality of the zinc has to do with its composition and the way it’s made. Pure zinc is not good and too far from pure is not too good….it’s the 3 bear and Goldylox story. Too pure and the crust up too fast creating a layer of insulation. If they do not corrode fast enough the...

Carl

I am very reluctant to suggest tapping anything, never mind "whacking and smacking"...although your right, that is the way to install. I've told the story of fitting a coupling that gets lightly tapped onto a shaft and showing the customer how to install and remove....easily with a couple taps of a ...

Carl

I agree. Its new technology which is getting better everyday. Ultimately its my belief that for small boats like ours generators will be a thing of the past in the near future. I think an awful lot of improvements need to happen before that can happen. I love my inverter but that is because I do no...

Carl

...what Rick said.

I also like to use B&S Zincs, heavier duty and they use real nice size bolts you can really crank on, not like those Camp ones. Even with the HD ones I cannot say I haven't heard a zinc hit the wheel when cruising. Quite a distinctive sound of metal hitting metal.

Carl

Very Nice !!

Carl

My vote is to Change the trans to match the ratio you have. ZF come in different down angles including none, as in straight like your BW. You'll most likely need to modify your mounting location...not a big deal. Take a look at other boats with gas and ZF trans If so, its a matter of shaft length. I...

Carl

I'm thinking if your going to go through the aggravation and cost of changing a motor as the counterrotation is a pain...you might as well change the gears to VF's. They are not all that costly...in the scheme of changing a motor anyway. I believe there is a demand for the velvet drives and can be s...

Carl

If you had the taller bronze struts, do you think you could cut to the desired height, tig weld it back together, use the pieces you cut out as filler ? Ive never tried to tig bronze, but with the correct filler material, i dont know why you couldn't do it, I have Tig welded Bronze but used bronze ...

Carl

With counter rotating props... how important is it to have similar gear ratios? for example, one side would be 1.88 ratio and the other would be 2.1 ratio. Can this be solved with more pitch in the 2.1 ratio? Is there a problem with different pitch and different rpm props on a twin engine boat? Wha...

YOu won't be sorry you did it the right way after your done. Running the East River, around Manhatten and Upper Bay, in the dark for your first trip there...man that takes balls. So much stuff in the water there aside from the congestion of the ferries, ships, tugs, boats... FYI- that was the Verraz...

I knew that we could donate money, books, pencils, copybooks, even furniture to schools, but....a boat??? Would never have imagined that! In dads old marina a 28 Bertram was "donated" to a church, one that sent the clergy out to meet the ships for services. The 28 had 502's...you know how a diesel ...

Carl

Congratulations!!

You cannot have found a better boat to dump money and time into!

Holy crap! That is some serious Locktite Right There!

Great advice on not running aground! I'd also try avoiding rocks and other none waterlike objects.

...anything more than 5 people is a crowd.

Anything is better than what was there...which in my opinion was really nothing and that nothing worked for the boats a long time. We could debate till the cows come home which is best...but till someone decides to run two or three boats up on the hard at the same speed, load etc and qualifying the ...

Your boat came with 10 degree and you built your own 11 degree? Yes and Yes But take a look at my old 10 degree struts, they are built for 1:1 trans setup which was the standard gas option in the early boats. This setup spun little 15" props extremely fast. There was no way I could open the bore en...

Carl

I used to race Porsches and always used to tell my fellow racers that owning a boat makes owning and racing Porsches seem reasonable. A customer that had a professional funny car used to say "Speed Costs". That seems to hold up true on land or in the water...I'd expect that's the case in the air too.

Carl

I'm glad to hear SALTWATER made it to your list.

She's looking great!

Carl

You don't even have to run aground...I straightened out a pair of shafts for a customer, the following day he hit a whale taking out all the running gear on one side. Or did the whale hit him?? In any case, I went with epoxy coated marine ply for my strut pads, I did the best I could and pretty happ...

Plan your food right, a couple of coolers and dry ice and you can keep food easily for a week layover. We do a week at fire island, two coolers, one for drinks, the other for food. We deep freeze what we can before going, use block ice and have used dry ice. By weeks end the frozen stuff isn't quit...

If i remember right, you boat had 440 chryslers ? When you repowered, did you change gears and props? If so do you remember the original gear and prop vs the new gear and prop? Maybe speed and rpm vs new speed and rpm? I bought boat 26+ years ago with 440 Chryslers running 1:1 gears with 1-1/4" sha...

Carl

Carl, I don't think we are that much thirstier than other boats that get up and move. With your Cummins I bet you get around 1.5 mpg, up to 1.67 if tweaked a bit. Yes my Cummins are well within that range...but the boat being looked at I believe is a carbureted gas boat. Run it slow at 17-18 mph wi...

Carl

Plane tickets and a cab ride is a lot less pricey then 21k only to find out you have a boat you can’t use. If your not one to know exactly what your looking at… Before I bought my RTO diesels I wanted them checked out. Me I knew so little about them it didn’t pay for me to go so I asked a friend who...

Carl

Thanks Doug— looks like what I used to use for table side Flambé when working as a waiter. I imagine they work well. I’m fine with what I have. I’m just describing the time I pushed it too far…that was 23 years ago. Damn….it almost seems like yesterday. Anyway. I put my inverter system together for ...

Carl We have used a Coleman propane stove in the past, when staying offshore overnight. Made coffee and heated up Beef Stew. I am sure it would easily boil water and make pasta. Use to set it up on the deck. Not elegant but it works. Thanks Tony. With the magma grill I can take the grate off and th...

Carl, The trick is charging two types of batteries at the same time. In my case it would be Lithium (house) and AGM (starting). My current plan is to use each alternator to charge both the respective starting battery and add to the house charge. Its also my understanding although I have not verifie...

A strip of 1/2" builder's grade plywood 3" wide and 2' long breaks relatively easily over a knee. Plywood is a laminate, once you cut it to a 3" strip you removed the tension of half the layers greatly reducing its strength. Certain materials shine in certain applications and lack in others. I'd sa...

Carl

I'm going to lean the other way a bit. Structural on the 31 Bertram is usually not the stringers...the wood inside was only a form its the glass encasing that wood that IS the structure. The boat can run without bulkheads, floor supports decking etc. Those last parts DO rot and will need to be repla...

I haven't researched it to any degree, but charging these batteries is a common practice. The Toyota Prius only charges its batteries when underway from both the lil gas motor and regeneration.
