Hull Condition Opinion

[KomatY26]

Hi all,

New here, first thread. Proud owner of recently purchased Yamaha 26C boat, located in Tokyo.

I hauled out boat last weekend to check the hull and it looked quite good without blisters or any serious damage and not much biofouling.

Only thing that raise concern are 2-3 patches of flaked paint on the hull and about dozen on the rudder.

I suspect that ex owner was painting antifoul over the layer of old paint, but again I am not sure what is this pinkish / reddish stuff below. Is it paint or primer / gelcoat?

Any opinion will be highly appreciated.

Looks like old RED bottom paint which was lightly sanded before adding new layers over it. At some point it the tenuous bond between the layers just let’s go and you are left with this result. The cure is to strip all the existing layers off and start anew with barrier coats prior to your antifouling paint of choice.....if you want the best result.

Looks like a minor paint issue, nothing major.

Yup. Second and third Jim and Bill.

She does need a good bottom job and repaint at end of season, though (or now, before she goes in, if you have the time/inclination/can book the resources).

Easiest would be to soda blast the bottom to get everything off before a fresh coat of paint (the fresh coat of paint you could do yourself), whatever colour you want.

Fair winds!

Thanks!

Yes, I will wait for end of the season to do that as I want to enjoy as much as possible at the moment. Biofouling is quite tedious here in my marina so I will do complete cleanup and paint job at the same time.

Thanks Jim for reply and clearing it up. I suspected that red might have been the former color but the gritty texture got me thinking. I will definitely do it from the gelcoat up once the time permits.

Also the keel caught some rust so have to do some metal coating as well at the same time.
