The 28 does not have a door window and I need one too.
Just because the 31 window will not fit, I inquired and there are companies that can make a new window to measure.
Therefore don't lose hope, if nobody shows up with a spare window, you can still make your own!

Yannis

Interesting... I believe climate, geography, wealth, age, vacation duration etc, all these criteria and many more, dictate more or less the type of boat one will choose. From the monstrous CC or RIB, to the yacht, to the sailboat, to the trailerable skiff and so on... It’s like when you pick a stati...

Yannis

Irrelevant, but I'm asked to abandon my adblock to be able to see your link.
I will not see your link therefore, thank you.

Yannis

I have tried so many times to understand the reason why people buy these huge ribs. To start with, almost none of them sells for less than 100K, so the claim that they are economical is not too credible. Then, comes speed. I understand that this is a true benefit, but could speed alone be a reason t...

Yannis

Carl, you could be right if people didn't spend 300-400K in huge RIBS...
Over 9-10 m. With 2-3-4 outboards. That surely don't fit in the garage or the side of any house...

Yannis

A bare Boston Whaler Montauk 17 in Greece, costs 57,000€ without the motor.
With a 100hp it goes up to 70,000€.

And, at the same time, people want to buy a perfectly functional and safe Bertram 30ish for 30-50-60 K !
I’ll burn mine but will never sell it that low...

Yannis

Carl, the jet drive will save my toes but will break my back (to lift into the Bertram). Tony, the 2,5 suzuki was 4 stroke. The other various two strokes I have are legal, who still has them can use them, you can no longer buy new two strokes. If you ask me, however, they should have allowed two str...

Yannis

I understand your situation may be different. For a 2m dinghy it is pointless to carry a battery just to start a 2.5hp engine. Besides, the longest distance any such dinghy will travel is max 100m. From the beach to the boat. When I said that there is no safe way to start a motor at night, I meant t...

Yannis

I hear you Rick, starting a hinging project on the gutter side is not a weekend task!
And usually while trying to fix one thing, there are two other new issues that pop up...

Yannis

Carl, my comment was for Rick. I know that your configuration doesn't allow for a rope and pulley system.

Yannis

Carl, you cannot have a battery in those little boats, especially the inflatables which are true inflatables, not RIB's.

As for not knowing where I'm going, well, you got a point there, I mean you must know things!! haha!!

Yannis

Neil, I have a 3,80 inflatable with a 15 yamaha 2 stroke, a 4,25 fiberglass fishing boat with a 25 yamaha, two stroke too, I have a Bertram 28, I have an inflatable dinghy in the Bertram, I have more boats than the mean European, American, Asian,could envisage (not cost wise, quantity wise) I'm happ...

Yannis

Much before Bob, may I say that all this discussion about prop angles and various prop sizes and multiple bow attitudes is all a matter of speed. Therefore you may never attain the optimal speed, nor the optimal consumption, but always consider that what made this boat what it is is nothing of all t...

Yannis

Yes Carl, I understand.

So,if you eliminate the hinges that are aft and instead affix a piano hinge (or two sturdy hinges) on the outboard side, then you could lift with a pulley.
It doesn't seem such an extraordinary task, why not study if it's feasible?

Aaahhh! I never thought my eyes could witness something like this!!

Yannis

Tony,

In the second pic that Shannon posted on Jan 6th, it is obvious that the box opens 100%. If the box is also hinged on the outboard side, I see no reason why it should need to crash down on you, with a pulley system attached.
Unless if all the 31's are NOT made the same.

Yannis

What is the original way these boxes open? I'm asking because, as I see in the pics above, the rope and pulley system looks as if attached under the lip of the flybridge above, it could very well open the box all the way, as well as keep it secure without fear of falling. For it to be applicable tho...

Yannis

Opening is one thing, how about sliding back all the cover towards the aft?

Yannis

As they progressively appeared, Im still laughing with ktm’s despair that we’re quarreling in any manner! On the other hand, he’s got a point, don’t know how useful to us with real boats, but a point nonetheless. Then comes Danny with his ever eloquent explanations, forgetting to admit that all thes...

Yannis

Yes, Tony, and this damn roll is the result of a super vee in a shorter boat... Mind you though, that for us here who almost never use our boats for fishing, in other words, who are almost never static/idle in the middle of the sea, we are not really influenced by any roll! We are either cruising, o...

Yannis

Carl, Happy new year to you and yours! Thank you for your comments, I sense your sincere desire, to the point of jealousy perhaps, to hop on the model with the deepest vee in the Bertram family, as well as the best seller of all Bertram models ever! So, the invitation is open; if you can't make your...

Yannis

It is somehow a permanent issue because you have chosen to differ in every measure possible! Even when you just say “dozens” of anything really, we say “tens” ! Anyway... The 31 must be a little more economical than the 28. I think that Dug S. who runs 4LHA’s in his 31 has better figures than me. Ei...

Yannis

Thanks Doug!

Yannis

Rick,

Why don't you install two stainless eyes, one on the box and the other on the pillar (or wherever you think best), and pass a rope and pulley.
When you're done, you remove the rope and pulley and you are left with only two permanent stainless eyes...

Yannis

Tony,

The oil embargo started in October 1973.
My boat was built in November 1972

Do you mean to say that they had already started saving on materials one year prior to the embargo?

Yannis

Tony, Is that so only for the 31, or for all the Bertrams? When I changed/inspected my through-hulls, I saw a 2cm thickness in the bottom. I consider this a "tank build"...mine is a November '72. I wonder if you cut through a modern bubble boat of today, how much thickness there is in the bottom of ...

Yannis

Hahaha so correct, I fell on the floor once and my 200+ pounds felt it. Took my precautions since.

Yannis

Carl, they may have erroneously taken the bare boat weight without the motors.

Yannis

The easiest thing on this planet is for something to be cheaper than...

Yannis

My 28 with 4LHA’s burns 2,6 liters per nautical mile, all yearly miles and idling combined.
The miles (which miles?) per gallon notion is unknown to us.
Or, around 60-65 liters per hour at 24-25 nm cruising speed.

Yannis

There are several discussions on this site that point out what Doug says, in other words, that visibility is severely obstructed by the bow. The fact that many sedans exist doesn't adequately explain about visibility, as it is the speed of the boat that determines the bow attitude. Perhaps, with old...

Yannis

Tony,

My son lives and works 2000 miles from our home in Athens.
So, even if we used our boat for fishing (which we never do), it would still be difficult!
Like I said, we feel lucky to talk once or twice a week...

Yannis

Jason,

How beautiful these kids!!

I remember when my son was that age of all the plans and programs to keep him and them busy.
Now, we're happy if we receive a phone call a week...

Merry everything to all !!!

Yannis

Shannon, I'm well aware that the use of pleasure boats in the US is very different from that in the Med. However, if you have the intention to ever spend a night or two onboard, keep in mind that the 28 cabin is more generous than the 31's. It is wider, especially in the V berth area, it is longer o...

Yannis

SR, Please give us a name that we can use, instead of initials. Then, you probably realize you're limit offensive for moving from a 28 to a 31...LOL !!! Nobody has done that, and the few who may have gone down this perilous path haven't to this day dared to admit it... Good luck in rendering your bo...

Yannis

SR,

Don't let Jason's work fool you.

This boat has the front windows glassed-in and the head separation wall serving as an additional support element.
I don't know if just the laminated wooden supports under the remaining ledge alone could be enough to support the fb weight.

Yannis

Carl,

Why not take your mold to the lexan guy and let him do the necessary?

We do not know everything and it may become expensive to learn by trial and error.
My .02 eurocents.

Yannis

Francesco,

How do you consider AC and heating without a bulkhead? Even a plastic partition wouldn't provide any insulation I think.

Yannis

Carl,

After the plaster mold is dry, you can then reinforce it with plastered-on wood strips to prevent lateral twisting.

Then, if you're not sure or just cannot do the heating of the plexi job by yourself, you can take the reinforced mold to the plexi technician and he'll do what's necessary.

Yannis

Does the addition/extension go both ways? Vertically below and horizontally at the trailing edge? Or just one of the two?

Yannis

Carl,

Hit this on you tube:

“Process of making unusual form for aquarium like a beautiful woman body”

Yannis

Tony, raising the manholes after a road improvement is normal. It cannot be done during the laying of the new tarmac.
However, digging right after a new layer for sewage, or electricity, or internet...well, we do it too!
I guess all govts behave the same because its not their money, its our money...

Yannis

Has anyone tried to make a mock up of the curved windows with plaster bandage? They are sheets of fabric impregnated in plaster that, once wet, can take any shape. You can apply them on any surface and once dry they make a cast that can then be used as a mold for plexiglass which can be heated to sh...

Yannis

There is yet a more frightening inlet in France which not only is much narrower than this one here, but it also has shallows and scattered rocks...a nautical version of the Russian roulette, with more than one bullets in the barrel...

Yannis

Yes, Francesco, something wasn't quite right when I wrote 35...it was a 38. I remember having read that article. By Aegean you probably mean one of the marinas in Attica, I cant think of any island port during that time secure enough for winter conditions, let alone the non existent facilities. Now ...

Yannis

Tony, The few Bertram variations that were built outside the US Bertram facilities, were all Riva-Bertrams (like this 25) in Italy, perhaps also a variant of the 35 (?) that Carlo Riva used himself, and the 28 Caribbean built in Australia. I'm not aware of any others....perhaps also an Australian 42...

Yannis

I thought boating was supposed to be fun...
So, probably, all this shouting is their interpretation of enjoyment, certainly not fear! lol!

Yannis

C’mon guys, no one in their right minds would spend 6-800 for a panel like this. This brushed stainless or aluminium already exists in sheets, suffices to find a used panel to take dimensions of. The holes are custom anyway.

Yannis

Cam,

This with the outboard. With inboards positioned half way under a heavier hull would they still lift the stern?

Yannis

Is it this one?
