Crack? Or an old patch?

[Jimmy J]

It appears someone has tried to reinforce the area from the inside (I would say the boat appears to have hit a Dugong, or a Manatee, except they are scarce in Ontario !) but did a rather slip-shod job, and only made doing it properly, more difficult. Properly reinforcing it from the inside seems the way to go, once you have identified the size of the affected area, which needs to be well over-lapped.

A dugong? The boat is from Florida some place so maybe it did hit a Manatee haha, not sure of the journey to ontario but luckily for me its here. Im curious to open it up to have a look.

What is the discoloration caused by?

Thanks

Discoloration...outside, its the color of resin.

Inside...dry or poorly wet out glass.

Structurally the outside is almost irrelevant, do all the work on the inside and leave the outside until later.

As Ondarvr says, it is a lot easier to assess on-site, but certainly the inside is the place to attack to make it structurally sound, the outside is largely cosmetic, but you don't want cracks that allow water to migrate into the laminate. Hopefully the access to the affected area from the inside is adequate, it is at least somewhat accessible, as your pictures show. If it wasn't, you might baulk at the job.

Ill try cutting into that shoddy patch from the inside to have a look, ill have to wait a few days, once im inside the patch ill post a few pictures and get your guys opinions if its worth even fixing.

Thanks for the help guys

Grind off the white layer of roving and see if it exposes fractured glass.

Don't grind through though.

Ill give it a go, I work in a big machine shop so I have excess to any tool ever made.

Could I use a wire brush on a grinder to shred some of it away?

cheers,

Wouldn't be my choice. Because I can't control the depth of cut well with wire wheel.

I would use a 36 grit disk sander

Will give it a go, thank you

A Wire wheel won't do much.

Grind off the roving and put some water on the surface, it will allow you to see into the laminate.

That is a good suggestion, wipe it with a wet sponge after sanding.
