GRP hull issues

[Andy dot]

Hi,

I am looking for my first boat and have an option to buy a cheap 2500£ Dufour Arpege 30 but it has some issues with the hull thai I sm mostly concerned about.

The engine is a yanmar 27 installed in 2020. The cabin lookas okay, the mast seems solid.

Can you please help me decide wether it is worth working on it or walk away ?

Thanks,
Andy

I see decades of old bottom paint which have finally decided to spontaneously remove themselves since no one was nice enough to strip it off through sanding or sand blasting. At some point all bottom paint will do this. It is nothing to worry about. Remedial action is advised or it will continue to deteriorate at its own pace. It’s really best to remove it, barrier coat the hull, and cover with a fresh coat of antifouling paint.

In looking at the pic where the chip is largest, it looks like someone painted over slime there. Bottom paint does not adhere long term to slime.

As Orion Jim said, it looks like bottom paint buildup, and it is long past time to remove it and start over. When you get down to the gelcoat, you'll see if there are any blisters. Soda blasting over sand blasting is easier on the gelcoat, and you don't want that removed. If there are no blisters, you can elect to just prime and paint, without the barrier coat first. The barrier coat is an investment in the future, and you need to get the thickness right. (Talk to the manufacturer.)

The hull looks OK to me, but I'm an amateur.

I see mostly paint damage there not grp damage.


Except that one image with something peeling off in a larger swath. What is it - below the peel - is this bare laminate ?


Maybe it was hard knock when lifting.


If this is bare laminate there, you want to clean the larger area off and then paint over with some layers of epoxy. Normally 4 layers are fine on a boat that sails only in the season. More coats if she permanently sits in the water.
