Hi, Im a newbie trying to buy my first boat with low budget and found this old boat for sale. Need some advice.

Are those blisters in the hull? Or it can be just bad paintor?

If yes, how would be to fix it by myself? Material is expensive?

Thanks in advance for any advice

Theres this rust, wich I guess its water pouring from the keel. Just want to know if its viable to fix it

That file is too big for Google to scan for viruses, but I downloaded it anyway. A lot of the spots I saw were just defects in the paint, but at the end you put your hand on first nasty rust coming out of a hole and then, I think, a real blister. A few blisters can be ground out and painted, or patched if they are in the structural fiberglass. The rust is a whole different issue. It could be the bolts holding the keel to the hull, and be a real problem.

Broader thought: How much of a project are the boats you are considering? Generally speaking, project boats end up costing more to repair than they would have costed to buy intact. That's why they have low priices. Then, they prevent a newbie from sailing, because time and money that would have been spent on the water is spent in the DIY yard. A better tactic is to buy a more modest boat that is ready to sail, and save the project for later in your sailing career.

That could turn into a very big job. Walk away and find another boat.

Man that's a shiny keel?
Weird, however if those are blisters( I think they are), look for them on the hull, if you don't see them on the hull then it's probably a bad ( paint)? Job or gelcoat spray job.

The larger issue as mentioned is the rusty streak.
That signals more inspection under it.
As the streak looks to be coming from the keel joint.
Good advise from tkeithlu on this.

Depending on how you feel about that boat, if it makes your heart patter, it's worth further research.
Keel jobs for a reseal are not cheap.

Looking at the aft keel joint this boat has been grounded some time ago. Water has entered the joint and keel bolts have started to corrode. To expensive to repair considering age and condition. Just walk away with tears in your eyes and start looking for another love.

Interesting video. I don't have any answers for you but I do have lots of questions:
You say you are new to this. Is that new to sailing altogether, or just buying boats? If new to sailing, i would suggest you do not buy a boat at this point. Just do lots more sailing - as crew or by charter. The risk of buying almost any boat is you will spend more time fixing & less time sailing.
Moving on to the boat in the video. My, thats a nice shiny underwater hull & keel. No antifouling paint at all. This boat is a racer designed to live onshore out of the water, not floating in it, right? Just asking.
Looks like a bolt on fin keel - probably cast iron? Or could be lead. Put a magnet on the fin & see if it stays there.
Blisters on boats are a major cause of concern where the boat is fibreglass. Its a condition called osmosis. Applies to glassfibre hulls ONLY, in boat terms. So your blisters on an iron keel cannot be osmosis but could be evidence of fairly major rust corrosion bodged over with shiny paint. Grind back to bare metal, apply a correct primer & repaint. Simple & easy. No ideas on the blisters if the keel is lead.
That rust streak. The video is not totally clear but looks to me like it is quite a way below the hull to keel joint & maybe a steel keel bolt down from the hull has almost penetrated to the outside of the fin, & the end of it is rusting. Might just need tidying up. My major concern is I really do not like that nice shiny paint job on the underwater hull & keel - could be covering up all kinds of nasties. But if the rest of the boat is similarly all nice & shiny, it may be innocent. May be. maybe not. If the only recent paintwork is that keel, I would be very suspicious. Dont believe what the seller tells you without solid evidence to back it up. Good luck - maybe buy a smaller boat to start with though... with less question marks ??????????????????????????

The boat is 34 years old. At the right price, buy it and bog it up. g
Grind out as far as you dare, bog it up, paint hull with roller and house paint and go sailing. When you finished with her, onsell to young person who will do the same thing. Learn to sail and upgrade when you can.And make sure you have a good bilge pump.

Do NOT buy that boat without advice from a very good surveyor.

Yes, the blisters on the keel are paint blisters and the rust stains indicate an iron keel or perhaps rusty steel keel bolts. That in itself may or may not be a deal killer.

The hull itself is another matter. The video suggests a very unfair hulll under that shiny paint. That unfairness suggests very amateur repairs. You need someone who can tell you what's under that paint. Looks a bit like lipstick on a pig to me.

These may give you some guidance.

From the video that could be a cast iron keel. The rust looks like bad prep.

Would need to pop a few of those blisters to determine if they are osmosis or air bubbles under paint. Osmosis blisters would contain liquid, often under pressure so wear gloves and eye protection.

Searles · 08-09-2021, 03:09

If that is an iron keel,that may have been glass encased ,if so it maybe osmosis blisters,in the glass and fillers used !however looking at the video of the hull in general ,in my opinion ,walk away ,many unknowns ,too many .⛵️⚓️

Never seen "osmosis" in an iron keel.
