Re: Repair a LARGE hole ???

bubba....sorry i been away......just saw this.....


you need to do an ....inside-outside-repair........simply put.....you glass from the inside first......

from the outside.....feather the edge of the hole back an inch or so on both sides.
using a plywood or arbourite type material that will take the shape you want.....apply that to the outside....(heavely waxed).....run a thin layer of csm only......let cure......then over lap the inside with multliple layups.....build the thickness......let cure.

pull the outside form.......grind the newly glassed layers so that they no longer have that outward bubble layer...and you are even with the featherd outside inner depth.....then glass from the outside....a couple or three layers of csm to get the hull thickness, then a layer or two of finishing veil.....(make sure that the csm is allways next to the substraight)....

then just fair and re gell.

it sounds like a lot but it isnt.....just time in cur fairing.

besides all this bubba....a fifty footer?..what the heck are you getting your self into?

then feather the edge of the

SO it's fiberglass.... tell us more. What engine(s)? What type of drive(s)?

What was it's primary use? Was it a party fishing boat? Pleasure craft?

Heck fill the hole with lexan and have a big bay window!

Ayuh,....

Is it still a Bay window when you get out into open Ocean,..??

Re: Repair a LARGE hole ???

I think the masonite idea is a good one. You can cut strips if needed and make a base form. Once the hole ain't a hole, you can finish the repair with multiple layups and fair it out with a long-board da sander in a couple of minutes a-la Bubba1235 "and then a few minutes (ROFL) with a long board"

Seriously, though, it sounds like you have a good deal going. What is the boat? I see some comments about 50 feet? You probably should pay attention to someone else besides me- three of the average-length boats I have worked on barely add up to 50 feet

Most any backing you can find that somewhat conforms to the original shape will work as a mold surface, of course the better it conforms, the easier it will be shape. Typically it's done like oops! did it, get the backing as close as possible and when you pull it off it's not nearly as close as you expected. At this point you just get out the grinder and sand off everything that doesn't look like a boat.

Whether this yacht is worth it is up to you.

That is the true beauty of a glass boat....

Wow, thats quite a boat...it does not look like it has any real radical lines, so I would think it would not be hard to form a form out of 1/4 inch luan or sheet metal.

Of course the Bay window idea sounds good too.

If you have the means, then I say go for it. Think of it as a second home.

If you're not going into debt for it, and you can cover the extra fees for a big boat (pay to put it in the water, pay to move it, pay to insure it, pay for fuel, pay for maintenance) then it looks like a fantastic deal in the condition you mention.

But for that much money get a surveyor's report done and make sure it'll be an investment and not a money sink.

Re: Repair a LARGE hole ???

To be honest, the repair should of little concern, it's just fiberglass. The concern is the cost of moving, storing and fixing all the other little details that pop up while you're working on it, it can run into many thousands on a boat this size. Even free it would cost several hundred per month just to own.

I need to type faster so I can beat you to the reply, it sounds like I just echo what you say.

Re: Repair a LARGE hole ???

what is the market like around there for a 50 footer bubba?

after you fix it .....can you sell it?........

1.5 seems ....well....uh.....just a little high for a 50.......500.000 ok.....but 1.5?

if you have the margins there.....and the space..( what onda rvr said is very correct)..id go for it, but......just do a core sample......thats one heck of a stringer-transom job.

Did I miss something? Where did you get that figure of 1.5? Five cents on the dollar comes to around $65,000 and that is figuring the AUD. I have no idea how that compares to the USD. Anybody got a conversion table?

Or am I completely wrong?

Ayuh,..... Don't ya Hate that,..?? Don does it to Me, regularly in the I/O forum,...

The point you Both raise is in fact the real Deal maker, or Breaker....

I won't/ Don't even try to think about the Co$t, per night, since I've owned it, would be on My Steal of a Deal, 34' Houseboat....
Probably a couple or a Few hundred,... That's with Minimal maintance co$t$,...

I already owned the Moorage....Just can't winter store it on My property...

Re: Repair a LARGE hole ???

For the work involved & considering what you want as a finished result I would recommend spending the time and effort to make an accurate & fair (smooth) partial mold based on the other side of the boat. Remember, 80% of the work is often in proper prep work, and this will make the final fairing much easier.
If it were me, I would draw some reference grid lines in exactly the same locations on both sides of the hull (extending past the hole on the damaged side). Then, on the good side of the boat I would trace and cut a series of (for lack of a better term) ?inside out station molds? to perfectly fit the outside shape of the hull. These could be cut from just standard 1?x pine, shaped to lay exactly against the side of the hull. Then I would fasten these in the proper spacing to a strongback, so that the whole assembly could be held against the hull to verify that all the station sections lay smoothly in contact with the hull. Next would be to take this assembly apart, and reverse the order of the station sections to give me the mirror image that I need for the damaged side*. Finally I would strip plank the face of this assembly, just like building a section of strip planked hull. Now you have a fair & smooth secion of mold to lay up over the hole in the hull (using the grid marks to locate it exactly right), and make the repair from the inside just as the original hull was laid up.
* An important step that I did not write in for flow & clarity sake is that each station mold section has to have a thickness of wood cut off its face equal to the thickness of the ?strip planking? in order to maintain the same final curves.
The face of this whole assembly would of course need to be finished properly for laying up glass onto it.
Time involved in doing this, yes, but the end result will need very little fairing.

Re: Repair a LARGE hole ???

time is the big thing......after you got done doing all that.....id be finishing the fairing......the fairing is the beauty.....if the fairing is right....no one will ever know........it doesnt matter how precice you make a mold for a repair....you are still dealing with depth of glass......thats where the fairing starts.....its the fairing that will make or break the job....




and bubba........i wouldn't worry about the "top section"......peice of cake

Re: Repair a LARGE hole ???

Great boat Bubba !!! The only thing I see is the "kitchen". I think on a boat that awsome they call it a Galley. How much "demo" will it take to get at the inside of the hull? Can you do the woodwork? That wood looks more like glass and I'll bet you can't see a joint anywhere, It would be a shame if you could not get it to look like new again. Otherwise GET IT...
