Wil, The construction of the anchor bulkhead (material, thickness, fastening method) is a function of the volume AND weight of the chain/rope that you will carry. From what I can understand from the pictures, the depth of the existing locker is too shallow to safely carry a lot of chain, due to the ...

Yannis

Thank you, Danny, I added the hyphen you suggested.

Yannis

When you say enclosed anchor locker, do you mean completely sealed on the cabin side? What you may find very useful is a glassed vertical surface of around 10cm height, across the bottom of the opening. This will prohibit any chain or rope to slide back during serious wave conditions. It will also p...

Yannis

I envy the emptiness of this bow. The first thing I would do is a bed of... Olympic dimensions!! After the bed, I would place the galley, head, etc where they fit. PS: Do you plan an anchor/windlass combo ? I do, and I hated that each time I pulled up the anchor all the water would drip into the bil...

Yannis

Tony, you're right...electricity has not reached us yet...LOL

I was thinking to not always use the fans - I have two - because they consume electricity and they are a bit noisy.
I'm thinking this hole/duct project quite some time now...who knows, one day it may come true!

Yannis

Carl, stringers, not strakes, you’re right…
Oh well, so long as stupidity stops right there!!

Yannis

Wil,

I hadn't seen separate little strakes forward, like this.
And I haven't seen strakes not symmetrical to the keel line, either!

Yannis

It will be in the way... Imagine wanting to get up at night and stumbling on the rope that ties it down...haha! Alternatively, similar to the idea of the duct, a hole on the cabin roof or the salon ledge above the pillow area, with a scoop that directs the breeze down below. Only problem is that the...

Yannis

Carl, I have the fwd hatch and it creates enough breeze, even on calm days. The problem is that this breeze is funneled from the hatch directly to the door, and the corners of the two beds (where most of your body and head are) are not influenced by it. These two corners remain hot, hot! I have anot...

Yannis

I'd take a good photo, yet better a paint flake, directly to Alexseal. They would know.

Yannis

Interesting points! There exist though in the 35 and above. In the 33 they are placed on the sides of the step, on the bow area above deck. The 28 has a similar step, only it is too narrow to place a porthole, let alone an opening one, where the frame should be more significant. I have seen some ova...

Yannis

Has anyone installed/do you advise in general, to put two small OPENING portholes on the sides of the bow - where your head pillow would be (that is just fwd of the cabin bulkhead) on either side? It gets very hot in the summer and these additions would probably create a draft in the cabin. My fear ...

Yannis

Moving the anchor locker will most probably lead to very minor change. The gain will come from the moving of the main bulkhead aft. I moved mine by 15cm and its a real comfortable difference. You don’t necessarily have to do both sides. If the bulkhead provides structural support to the topsides, th...

Yannis

For heavy/voluminous items that we want to ship within the mainland, we go to the central bus station and ask to put it in the bus’s loading bay, for a small fee. The recipient awaits for it at the other side. As a matter of fact we do the same with ferries, if it is an island destination. For a sma...

Yannis

Do you plan to ever sleep in the boat?
If yes, now is the time to position the new bulkhead aft of its original position, at least on one side.
This will be at the detriment of the settee or the head plus galley side, whichever you choose, or both.
I’ve done it in my 28 and it’s a whole new world!

Yannis

My thought is that a through hull is a hole. It always was. So, the higher from sea level, the better. There are nevertheless some parameters, such as the higher they are placed the more is battery consumption, or the less is the output, however, the stains on the hull is not a parameter. Is it desi...

Yannis

In a small rig the valise type is much better because it can fit where the container type cannot. It is also lighter. Some caution however must be given to not wash/rinse the boat with caustic/chlorine based chemicals that might reach the area where it sits. A friend who has a 8 person container typ...

Yannis

Tony, I agree with the yearly use. That’s why I wanted to test it, as I did. However, I believe that your furnace, any furnace, is a much friendlier environment for scale buildup. Firstly, because it always operates at high temperatures, after all that is its purpose, and we know that scale deposits...

Yannis

Thank you Shannon,

So if the coper got rid of its rust and became all shiny inside, does this mean that the calcium scale has been eliminated too?

We do not have barnacles, at least not inside the heat exchangers, nor worm tubes.

Yannis

I went down yesterday with a friend to see how to tackle the vinegar project. I started the port engine and let it run until the temp reached the usual normal temperature when idling on the hard, Id say around 65-70 C. Despite that temperature (on the temp meter), the water was coming out almost col...

Yannis

Yes, but how did they manage to insert ply between two layers of glass, of which the top one was the original sole?
Unless if the top glass was not original. In which case its outline can be clearly defined and gutted.

Yannis

Tony, thanks.

For us here who are not in the least concerned about freezing, how important is it to make sure that even the exhaust is full of antifreeze or vinegar?
How much should one be concerned about scale deposits alone, in the exhaust tube ?

Yannis

Rick,

Is all the hull sandwiched with this rotten ply? The sides too?
If yes, how will you establish the degree of rot? Will you be cutting through the inner glass until you find dry?
Holy hell, that's some job...

Yannis

Tony, the boat is on the hard so there is no water suction from the seacock. I will turn the intake shut, so that the vinegar doesn't drain under the boat. I agree with the antifreeze quantity, however here we are talking about the raw water circuit, not the antifreeze closed circuit. I have no idea...

Yannis

I have seen two different variations of the above layout:

One with a longitudinal bench, in continuity to the engine box, where the double seat is,
and, another with two longitudinal benches on either side and the wheel on a tower.

Yannis

Perfect! Here’s the plan: Start the engines with water provision through the flush tap, as usual. Let it get hot to over 60C. Turn engine off and remove water source. Connect the 4 liter vinegar jug with a hose, after I shut the seacock. Restart the engine till vinegar is sucked. Turn engine off and...

Yannis

The 31 Bahia only has the forward V berth and a small galley at port and a head at starboard, inside.

There is no salon inside, the salon space is taken up outside by the commanding post on one side and a bench on the other, just forward of the engines.

Yannis

At idle the garden hose without reinforcement doesn’t collapse. I wouldnt touch on the main seacock hose, that is remove it from through hull and stick it into the pail, I will need a monkey to go down there and undo the ring screw and then, as we all know, I will not be able to put it back together...

Yannis

You mean to say that instead of holding the jug high above the engine and let gravity do the rest, I could fill a bucket with the vinegar and drop the hose in it - the other end attached to the intake flush tap? Does the engine suck by itself without the need of gravity? I assume I should turn the p...

Yannis

Carl, Rick, Tony, There is a 4 liter vinegar jug sold in supermarkets at 6% acidity, that I use as is in the washing machine prior to leaving for the summer vacation. It keeps the machine clean of scale, or so i think, because I can't open it to verify. I also use it in my espresso machine and there...

Yannis

If the CLR or any other barnacle buster can sit in there for hours, I don't see vinegar posing a problem. After all vinegar is much less caustic than any barnacle buster. On the other hand, there is no barnacle issue here, just calcium deposits. Now if I manage to get this vinegar into the system wi...

Yannis

Carl, The Yanmar pink cooling liquid is not affected; I'm talking about the raw water which circulates from the intake to the exhaust. So instead of raw water, replace it temporarily with vinegar. Now, I'm not too sure how this can be done but if someone has done it I would like to know if it works....

Yannis

Does anyone know if I pour vinegar into the raw water intake while the engine idles, and make sure that it stays inside the circuit for a few days, if this will dissolve the scale deposits in the system? I'm trying to figure out an economical way to clean the heat exchangers without having to remove...

Yannis

Thank you Doug. I have the 4 LHA's, I recently went through the ordeal with the turbos, so I'm kinda used to hearing exorbitant prices... I will have to go down to the boat and see how similar these mixing elbows are to mine. Then, I should ask around to see how much they sell for over here, not exp...

Yannis

Doug, can you send a picture?

Yannis

Carl,

Alcohol can only have positive effects on the body !!!
For enhanced positive effects, simply augment the ration, what is it you don't understand!! Hahaha!!

Yannis

Carl, You will not notice anything just by swimming around the boat. However, if your anti fouling is ablative, then by definition it disperses constantly into the water and if you swim around it you're bound to ingest it as you sometimes rinse your mouth with water while swimming. Furthermore, what...

Yannis

The hard paint does not rub against you, the ablative does. This usually rubs on your back, without your noticing, as you touch the boat while swimming. You then sit somewhere and you pass it on the backrest of the chair... If it rubs on your fingers and you then touch your face and eyes...you will ...

Yannis

We avoid ablative anti fouling because we use our boats for swimming.

The water around the stationary boat is contaminated and as you climb up you may touch the hull that transfers the paint on you. Which is a poison...

Yannis

All this sounds logical.
However, shouldn't we have an indication of how much this site costs per year, so we can do the above calculations?

Yannis

Peter, I only use hard anti fouling. Every year I keep the boat in the water for 4 months (June-Sept). When I take her out in late September, they power rinse it within a few days. Before launching the following June, they pass it a mild sandpaper. Then, they apply two coats of anti fouling. Half wa...

Yannis

Tony, The only reason I will not fly to the US despite the numerous invitations that I have from my distant cousins in various states, is the duration of the trip (10h direct Athens-NY, if I'm lucky to get a direct flight) plus the 6h jet lag. I can't fit in the seat, let alone remain seated for so ...

Yannis

Tank you Bruce and Mike, and Matt for the improvement.

Yannis

Tommy, Tony, Carl, I thought about it, you know, so many times. There must be hundreds of Bertram owners here, I know at least ten people with 31s, 42s, 36s, even 30s! The problem is you guys are so far away...however, if any of you show an interest to visit our side of the globe, I will be very hap...

Yannis

Rick, I have a cousin who is a naval architect. He has built numerous boats mainly for himself, in his backyard. Every time he was launching a boat he would call me for help during the first few trips, just in case something went wrong. I remember that during the first trip of one of his boats, the ...

Yannis

Carl, thank you for posting what I am otherwise unable to post myself, due to the condition of my aging electronics…

Yannis

Are these meters?

Yannis

I'm used to seeing bottom and one thing we do is we avoid running over these patches, we go around always. The difference between the Med and the Caribbean is that in the Med all these patches, whether just pure vegetation or rocks or both are almost always very near the coast. In the Caribbean, as ...

Yannis

Carl, it's not your boat alright, but the tiburones?

Yannis

I chose the Invisible Resin. LOL As I clean every season, flakes of what was my bilge painted with by previous owners fall off and I collect them at the stern…I dont see why a bilge should be painted especially when it is such a difficult project with the engines mounted, UNLESS one starts with an e...
