I agree with you that a good ferro-cement boat is a good boat indeed. I do not however, share your lack of concern about the following:
“….which let in sufficient seawater to flood the armature to sea level. This isn't a big deal, as long as I flush and drain it”.
Spalling is the only true enemy of ferro boats. I wonder firstly how you can ‘flush and drain it’. Merely pumping fresh water into it will do little except make it wet, unless there is a means of having the water exit the hull, at a point below where the salt water was able to get in. Even so it will be virtually impossible to remove the salt without exposing the affected armature completely, sand blasting any rusted parts of the armature, and then replastering the damaged area. The process of drying the dampened cement alone can take weeks of fine weather even after the area has been exposed, especially so if the area has been wet for a long time.
Once water and oxygen has been in contact with the armature, oxidation will occur. As I am sure you will be aware, when steel rusts, it expands, and has the effect of causing spalling. Or, it starts to crack the hull making it weaker in the best of cases, and blowing it apart in the worst.
The problem is made worse being as it is in the bow. If this area of the boat is sufficiently weakened any collision with a wharf, or other solid object could have severe effects. Also the rig is largely dependent upon the integrity of the forestay and its anchoring point at the bow.
It is of major importance to address any breaching collision or water ingress into the inner hull as soon as possible after the event. The armature should be exposed and treated in all cases. Catastrophic failure may not necessarily result, but the likelihood of it occurring is significantly enhanced with the passage of time.
While there are many ferro boats still in use after over a century of service, many do not survive. In most cases it is not due to poor build quality. In many, severe damage occurred because the builder bid not properly crimp the twitchings, which led to rust, which spread and caused spalling.
As with home built trimarans in the 60’s and 70’s, it only took one or two badly plastered home built ferro boats, to damage their reputation. Nowadays, the cost of materials, and labour, make ferro boats far too expensive to build with the consequence they have almost disappeared from the modern boat building lexicon.

I'm going to have to ask for your credentials or experience. I will not discuss a subject with someone unless they are sufficiently knowledgeable and can demonstrate their knowledge. I have precious little time, and discussing the merits of my ship's hull with someone not sufficiently knowledgable is just a waste of my time.


Also, I will NOT get into ANY kind of argument with anyone over the merits of ferro-cement, and especially considering I have a laminated ferro-cement hull. I also have a little rule about discussing topics with people who are ill- or misinformed. I deal only in truth. If you wish to know more about Laminated Ferro-Cement; the US Navy put out a few documents on the subject.

Ferro-cement is the right material for me, and laminated ferro-cement makes it all the better. My yacht will outlive me, and it is the ideal hull material for my needs. So none of the ill-informed arguments anyone gives will ever deter me from ferro. Jealousy is the true motivator of those who desparage Ferro-cement. I don't have to wait for perfect condition to repair my hull; as long as it is above freezing, I just make some mud, slop it into the hole, brace it, and my repair job is PERMANENT. Do that with fiberglass! Do that with steel. Do that with wood.

Now imagine you are going to sail for real - an adventure, like circumnavigating Antarctica (first done in a ferro-cement) or going to the north pole unsupported (my goal). Do you really want to be in a hull that is anything other than ferro-cement? You hit ice, or a log and get holed; you have no port to pull into, no commercial towing, no shipping lanes - NOTHING. You have to repair that hole yourself, and it has to get you all the way back to civilization.


The cost to build my hull today is likely well into a million US dollars. So I think that getting my ship for $30,000 is the bargain of the century, and I owe it all to ignorance and prejudice. So in that regard, thank you to all of you who desparage ferro-cement hulls. You made my voyage possible on my budget!

First ferro boat: 45' Adams Whimoway, sailed around the coast of Australia and through Indonesia, Thailand, Malaysia, then across the Indian ocean. Second Ferro boat: Adams Aquila 55. Sailed from Australia via southeast Asia to Japan and back. During this trip I spent 30 hours in a hurricane. Owned and maintained ferro boats for 25 years...and I never needed to get nasty or overly defensive with anyone when addressing my passion.
I am neither ignorant nor prejudiced and have probably spent more time maintaining and sailing ferro boats than many...possibly even you! And my knowledge did not come from reading a book published by the US navy, it came from personal, hands-on experience.

Ferro, timber, aluminium, steel (my current boat) fibreglass; they are all good when properly constructed. The thing which makes the difference is not the boat, but the knowledge and seamanship of the sailor and if you don't have that...and if you are not prepared to listen to others without becoming aggressive, then you're not much of a bloody sailor.

To see how the real sailing community regard ferro (as opposed to the theorists who have obviously so influenced you) look at this link http://www.cruiserlog.com/forums/f12...ferro-525.html then do a search of these forums...you never know, you might learn something; such as: Awanhee was the first FERRO boat to circumnavigate Antarctica in 1970. It missed being the first sailing boat to do so by about 200 years (timber) and by many, many others in the intervening years made from alloy, steel and grp.

You are on my ignore list now for the simple reason that you assume WAY too much.

You do not know me, nor do you know my ship, nor do you know my experience, skills, expertise, or level of intellectual capability. And I did mention that I only deal in truth. Hands on experience is useless without base understanding. Do you know what Laminated Ferro-Cement is, and what its advantages are over ferro-cement? How many Fibersteel hulls have you owned, sailed, worked on, seen.

I offer a resource of knowledge, and you reject it, even while assuming far, far too much about what you believe my intentions and emotional state are.

And again, I said I only deal in truth. Why then would you judge me for not taking your "advice" when it is proffered without a lick of credibility to back it up. Do you expect me to simply take your advice because you have (uncommunicated) experience?

I have dealt with behavior like this before, and unfortunately, my experience (as well as my understanding of the underlying reasons which explain the behavior) dictate an extremely insignificant possibility that you will change your tune. As such, I am going to have to state that you will be ignored by me henceforth. I am far more capable of sailing my vessel and understanding it than someone on the other side of the world who feels his experience alone qualifies him to hand out advice as though on authority.

Please do not be offended. You aren't unique in your behavior here; most people act this way. It is an artifact of our system unfortunately.


I do appreciate your efforts and am grateful for them. But I must ignore the substance of your efforts on account of its inappropriateness for my particular situation. There is no judgement, and no hard feelings on my part. I just hope my honesty and forewardness are not misconstrued. I would shake your hand and express my appreciation even as I told you "thanks but no thanks for the advice" if we met in person.



I will ask you to please refrain from questioning my status as a sailor however; that's a bit far below the belt.

No one really talks like that. What the hell is an artifact of our system?
You have to be a complete fraud, coming along to stir up good God fearing people.

No one ever gets mad at Auzee. He is about as nice and gracious a guy as you are going to meet on here.


What is up with you? Blog Baiter?
