Rusty Keel Bolts - How far do I go??

Richard

'Galvafroid' is the stuff you want.

We used to use it on pushpits etc before stainless became the norm on yachts.

A good article Here on its properties and application.

Richard - Neutra Rust is just the ticket. And you can view / buy it HERE

Interestingly, there has to be some rust on the metal for it to work. Also, although I am a fan of SS (316) there has to be some merit in the fact that greater and more knowledgeable men than me make quality boats for a living!
 
I've done the same... sprayed with zinc primer from a can and then underseal, again sprayed from a can. A benefit of the type that doesn't dry is that you can more easily remove it to check the condition.
 
Hi All,
Yes--I'm a novice, so go easy! ;-) There's this Santana 35, cheap...sure, I know you get what you pay for, but this will serve my needs for now. These keel bolts look sad, though, which is a reel concern...if they break, I'll be screw*d (get it?! Standup, here I come!) It's a quandary, as it's over a grand to have a survey done, and I don't wish to pursue one on the boat if it's all for naught. Is there any way to properly inspect keel boats without having to haul her out and remove them, to know if it's worth pursuing? Relatedly, I know I should have a proper survey done, regardless, but I must admit, it's so cheap, I wonder if it's just better to accept it's going to have some problems, and direct the vessel to my specific needs until it does.

Any constructive guidance is greatly appreciated. No need to tell me I'm lost, 'cuz I already know that...that's why I'm here! :-) Thanks!

What a blast from the past :) Hard to believe these are my words from 10 years ago on Rogue. In the end, I had the keel bolts replaced in Malta in 2009 after a survey of the hull for reasons other than the keel bolts.... completely unnecessary when we saw the old ones, but the new ones looked nice, and helped when I sold her the following February.

Rogue then crossed the Atlantic, hung around the Caribbean for a few years, transited the Panama Canal, and sunk in a hurricane in Mexico last September. Pantaeneus wrote her off, and the hull was sold for a few hundred dollars to a local who apparently planned to refurbish her.

I have no idea what Daniel is asking for help with, but I wish him well :)

Welcome to the forum.

Your photo does not show here, but some general comments on keel bolts.

That is not a boat we see in the UK but from the design details it seems a very racy lightweight boat, so no doubt is showing its age. The normal way of attaching keels on this type of boat is by tapping into the keel casting and using studs or bolts, probably mild steel. These can often look horrible from the top as they usually rust to the point where the heads almost disappear, but, provided the seal has not broken between the keel and the hull the fastening itself (as Richard found) is usually sound. The only way of finding out is to draw one out, but if they are studs with nuts on the top they may not come out and you have to drop the keel with the studs still in it.

However, you can get a good idea whether the keel joint is sound by hauling the boat and checking whether the seal is sound. If water has got in then you will see heavy rust if it is an iron keel or water will run out if it is lead. time to run away.

BTW it is normal on this forum to start a new thread with your question rather than attaching it to an old one. There are regular threads here on keels and a search would find an answer for you. However each question like this justifies a new thread, particularly as the boat is unusual from a UK perspective.
 
I'd be inclined to extract a couple of them to see if there's any corrosion or necking further down. (I'm not a professional).
As far a cold galvanized products are concerned, I wouldn't trust Galvafroid - I've used it a lot in construction industry for protecting cut site cut ends on steelwork, cable tray and the like. The adhesion is not good and after a year it can be pulled off in sheets in my experience.
