Do-it-yourself boat bottom repair Crimea

Hello to all the water-powered brotherhood! On the occasion, I bought Crimea 3 with a Yamaha 90 engine. (I think that infa about the engine will cause a smile for many). besides, the serial number is 170. with the wrong steps. As you all understand, the body in the killed state is similar to the wave against which it is not recommended to “push the sneaker”. Napoleonic plans look something like this: replacing the bottom with 3mm AMg5, further use of the boat under the same engine. I am planning to walk around Pirogovsky, I will carry a skier, and I will also fish. Hence the questions about the repair: how and with what to fasten a set of frames with a new bottom without cutting out the old one? I'm waiting for your ratsuh!

It will be easier and possibly cheaper to take a case for this motor.

I changed the bottom in the Crimea 3.
It is possible to do this, but it makes no sense at 90l / s at 8g. deadrise of this building.

Crimea he is flat. and therefore if you put 60 forces and 90hp on it. the difference will not be great. but the fuel consumption is great. try looking for a case for your pit 90.

I will buy building Crimea3. (under Merck40jet)

If you honestly fell in love with this boat, you have long wanted this, before that there was an ordinary Crimea with whirlwinds, if they were not okay. that money is immeasurable that fortune. As a result, I spat on the state, bylb hands, I'll do it. The amount of work, of course, but it will delight the soul. A question to the respected waterman: how the sheets were shaped, I saw in the photo. Who will advise what about attaching frames to a new bottom, without removing the old one! Provar? There is no contact welding, only argon. Is 3mm thick enough?

Here is my Krymchik!

I cut squares on the old bottom between the frames and stringers and welded along the edges to the new skin. Plus, it was drilled with a 10 or 12mm drill. and cooked with a semiautomatic device through these holes.

Is 3mm thick enough?

I did 2mm, but I reinforced it with a bend. Without beading, of course, 3mm is better.

Forgot the photo.

Admire the people at the wounds of my ship. I can't say for how long, but this is a consequence of the economical consumption of luminescence and a powerful motor.

Crimea-3 and Pit F-100
Link.
The boat is alive. All are intact, but the power is excessive. It rarely goes on the meadow when the water is a mirror. It overtakes all the available import boats so that the boys do not ask themselves

Looked, thanks a lot for the link! Impressive. I want to make something like this out of mine. Pooh, I would be very grateful to see a photo in the process of repairing this vessel. What is the thickness of the bottom? How does the replaced AMG behave during operation? How did you achieve the evenness of the sides? I have cut out lockers. I plan to strengthen with a hollow square (rectangle) of AMG. While collecting information. I will document everything with subsequent calculation. I ask you to respond to anyone interested in Crimea 3! Thank you all for earlier!

So how is the bottom on the Crimea reinforced under the Ya-100. Pooh, take a couple of pictures if possible, I wonder!

All redans were removed from the bottom and a 4-5mm aluminum sheet was superimposed. The sheet is sawn lengthwise from the inside in the middle so that there is an even bend with an angle along the keel and not with a belly. Everything is attached from the inside with bolts into the body of the sheet. The thread is cut directly into the sheet m-4 or m-5. again from the al. corner in which one shelf is cut in height so that the redan stands correctly. On the transom from the outside there is also a sheet of Alum. the entire width and height of H-5mm seems to be through 1mm rubber as it did not look inside the transom. The board is glued from the outside with fiberglass, putty with epoxy, etc. Chel did 3 Crimea .2 on bolts. alum.when welding led and there is not such an even bottom. The boat is covered with snow on the boat, if I can get to it, then that I can take a picture tomorrow, but the pictures of the current in a personal. how to squeeze them here, I can’t figure it out with a computer ”I’m not friends” but there is no child: - ((

Thanks for the info! My mail: Thank you for earlier. Vadim.

Throw me off too, pliz

Sent to KRYMOVOD and VOLZHAK - I can't come here. It's hard for me. Drop the mail

eh baby.

Hello Lambo and my condolences for the untimely death of your brainchild. It’s a pity, a pity. How long has you been in operation with the H-50? I saw almost all the photos of your ship + video + restoration work, the hull was really in openwork, it is simply a rarity to find such a thing!

The work is progressing, slowly, it is possible to carve out time only on weekends, it is a pity for only two hands.

I drill out spot welding, I go first with a 3mm drill, then 12mm. It turns out like this. To date, I have removed all the redans.

There are several questions along the way. There is a hit board, the former owner did not bother with repairs, stupidly welded in places where it burst and that's it. Tell me who leveled the results and how. There is no experience of such work, therefore, I look forward to your recommendations!

Here is closer. Thoughts are as follows: first, loosen the amplifiers from the inside (also welded), then heat the area with a hairdryer and knock it out, pulling it up from the back. Advise people!

The case is nearing the purchase of material to the bottom. Here, too, there are still some questions. I ask the Waterman and who changed the bottom to respond! According to my measurements, the sheet 3x1500x4000 is not enough for the bottom (I mean to cut it in half). Merchant, sell the secret of forming sheets, how did you do that? What redans did you cook 30x30, more? Bent or finished corner? I like the version that Pooh sent, but for the sake of a strip of 40 cm to buy a sheet. do not even know. I am waiting for your advice dear forum users! Thanks in advance!

It was on the 1st Crimea for himself that he made a strip between redans, something like a ski. the other two have a completely closed bottom.

I understand, the option with the ski is just like it, where the thickness is 4 and the ski is 5k, is that all right?

Yes, the devil knows how he's got there. I'll take a picture from the bottom, but he doesn't worry about the bottom at all. On the ski, the total thickness is about 8 mm.

Re: How to straighten the bottom in the Crimea?

A wooden hammer and a block is the whole science. Today I straightened it. Only without fanaticism, you can break the metal.

Re: How to straighten the bottom in the Crimea?

I, too, had a bubble closer to the stern and cracked right along the bulkhead !! it’s not scary, it’s just that it just recently fell into the hands of the room!

Re: How to straighten the bottom in the Crimea?

How to correctly straighten the bottom near the Crimea?

Explain on your fingers how it is competently make? Do I need to heat the metal or "cold"? To hammer on the weight or so that the bottom of the raft lies on the floor?
Small dents and bumps all over the bottom. And the most important thing - bottom at a distance of 10 cm from the transom... There the bottom is crushed and the transom is like a scraping on the water. I'm afraid to ruin the boat.

Take new members to your ranks.
A childhood dream came true and last week my friend and I became the happy owners of Crimea.
Now we want to have time to bring it to an acceptable state before starting navigation, the budget, as always, is limited.

The corps itself, although "alive", requires our participation.
The previous owner did not care much about the boat and "somewhat" bent the keel with the bottom inward (apparently hit something), there are also a number of "battle marks" on the rest of the hull.

We do not yet have experience and understanding of straightening work in Crimea, we will be grateful for any constructive suggestions, and we will not refuse the services of a specialist.
Remained native seats and a sofa, we plan to restore and operate them further, in this part and in general, we also ask you to share your experience.

I propose to discuss the boat Crimea, Crimea, its pros and cons, fine-tuning (tyuneng) it for yourself.
I see the following questions:
Convenient bedding equipment.
Competent awning (on family or new arches)
Front seats (native, with shock absorbers, car, etc.
Stationary tank.
Payoli, miners, etc.

Here is a selection of photos to begin with [ [Links to union members only. ]
There is something about the tank that would not be repeated here https://my.housecope.com/wp-content/uploads/ext/514/vb3/showthread.php?t=16864

I completely agree for AMG either 3mm or "brutal" power set.
duralumin 1.5mm in this regard would look more worthy.
The beauty of the Crimea is not in its fortress, or rather even its rigidity, but in the absence of the need for care and the possibility of an indifferent attitude.
Here recently Zhenya Slavutich very aptly said “The Crimea has a bottom like an accordion, all skewed under the onslaught of an overstated engine power, but all the same, the infection walks and does not flow. So the conclusion of the people is simple - a strong boat ”, approximately somewhere like that.

And the roller there was metal and rolled with a sharp edge.

Good afternoon everyone. Once upon a time, a long time ago, they gave me a hatch cover from a boat of 5m2 (if I am not mistaken) and a counterpart (I call her that) from a progess boat for 0.5. For today, I decided to make a hatch to the Crimea. The counterpart from the progress is larger than the hatch, besides this, I was already given it cut into four parts for shortening. It is visually visible that the dimensions of the “response” are different, two sides (opposite each other) 10mm each and two sides (opposite each other) 20mm each. Besides, I don’t know what they did with them, but there are no strict angles in the response. I tried to level, straighten, - all the same there is no corner, and all the four parts (sawn) have otvetki. It turned out that although not very much 5-8mm does not coincide at the corners of the radius of the lid and the "response". And in general I do not like her, as the soul does not lie to the “answer”.

Now the question is: Help with advice, from what to make an answer. Maybe someone made it for himself, maybe he saw it from a neighbor, maybe there are some links to making, a photo, something else. For myself, I see a 20mm-30mm corner, sawn at the corners and bent under the radius of the cover. Boil the cutting points with argon, and put a car seal on the top of the corner which will be under the lid. In theory, it should be airtight.
I called on "tuning" "with theirs" answer "which is also from progress, behind their words, which, with their very, very diligent work, should come up. Well, it will be somewhere worth 400 UAH.
