lagoon 440 repair- big hole in hull

hi,

I intend to buy a damaged lagoon 440(see pictures).
I need some opinions, if possible qualified.
-what method to repair the hull?
- repairing such a vast area of the hull, is it sound, would it be safe, as solid as before?

regards,

Flo

Re: lagoon 440 repair- big hole in hull

I hate to be rude but if you are asking these questions, don't buy the boat. With a hole that big its not just repairing the hole. It also the replacement of quite a substantial amount of wiring, cabinetry etc and at the end of the day when you go to the seel the boat a good surveyor will pick out the repair work immediately and I suspect most prospective buyers will run, not walk away.

Re: repair advise -very big hole in the hull(lagoon 440)

It can of course be repaired, but it will be expensive. Hope you get a good enough price on the boat to make it worthwhile.
The trouble with damage like this is that it takes very time-consuming probing to get to the bottom of all the ancillary damage. It may be hard to detect whether the engine bearers are damaged/delaminated/compromised without pulling the engine. There may be core-shear extending pretty far forward, that would be undetectable until a builder attacked with a grinder.
Now, everyone will advise you to get a surveyor--and you should--but be aware that many surveyors are not boat builders, and the hidden damage I mentioned before wouldn't be detectable even by the most qualified person until a lot of work had been done to dismantle interior structures and gain access. So you need to do a lot of taking apart of things, a good deal of grinding, and THEN get the surveyor again.
Better to save up for a used one in better shape...

He's trolling us, right? That boat is worth about 25% of the value of the stainless, copper, and other gear you can scrap off of it. Probably less than that. Then you have to dispose of the carcass after you get anything of value removed.

In other words, if they gave it to you, they screwed you.

That would be my guess too. And if so, my answer is get some plywood, 5200, 10 oz fiberglass cloth, some epoxy and a case of beer, and make a weekend out of it.

Re: repair advise -very big hole in the hull(lagoon 440)

I agree with Benz. Thereís no way to really tell how extensive the damage is until you start grinding and taking things apart. I assume the boat was condemned as a total loss, which tells you right off the bat that thereís probably not a path back to a sound boat that makes fiscal sense.

If you were doing the work yourself you could probably do ok financially but thatís not a project if you donít have the right skills and experience...which you clearly donít since youíre asking the question in the first place.

In other words, the repair project could be a money pit with no easy exit. You buy the boat, get deep into it only to o discover it will be 4x the initial estimated cost. At that point you either walk away or complete the repair, both at a significant financial loss.

Thereís no such thing as a good deal on a cheap broken boat that needs professional repair.

Re: lagoon 440 repair- big hole in hull

That is a big hole indeed ! It certainly is possible to repair but I doubt anyone here will be able to tell you what to based on 2 pictures.

It seems she lost her mast as well, there is a huge investment to bring her back afloat. Did you get some repair estimate by professionals around ? When you do the math, don't forget about the lower resale value.

Keep us posted, this is an interesting project !

Re: lagoon 440 repair- big hole in hull

DO NOT buy the boat.
If they offer to give it to you, run away.

Would it be safe? Maybe, but youíll never feel safe.

As solid as before? Thatís the biggest problem I can see. That section if replaced would more than likely be more solid and stiffer than the rest of the boat. The boat will not absorb energy evenly and continued repair will be needed as cracks appear.

If you donít mind, what is the asking price?

One thing for sure is whoeverís looking to broker such a deal is shady.

hi,

thanks for the answer.
For now I was concerned if technically it could be done,
resulting in a safe and proper boat to sail.
Considering there is no extensive damage beyond what one can see, how many work hours would you estimate (to do a rough job)?

regards,

Flo

Hi,

That was he main issue, would the boat be safe?
I m not sure I understand what shady means in this context.
I may have it for 25000 $, if that s the question.

I may have it for 25000$, and frankly I don t need a boat to dismantle, but even so, consider that the mast alone, the generator and one engine are worth more than that...I think
And I m not sure I understand your calculations
