Alloy yachts

What are the pros and cons of an aluminiun alloy yacht?

Re: Alloy yachts

Can you be more specific about your situation?

Are you considering a new build, and if so, to a one-off design (existing or fresh), or a current non-alu design?

or are you in the market for an existing yacht, and if so, for what purpose, what size range, and what are your expectations around maintenance, resale, etc etc etc.

IOW, it would be great if you could ask your question in a way which will not generate a huge amount of irrelevant observations (and the usual fights among bystanders about the more trivial aspects of those irrelevancies!)

Re: Alloy yachts

Here, these people build both aluminum and fiberglass.

Not if you have an isolation transformer, no.

I thought an alloy boat could still be damaged if there is a potential difference across the hull? So, for example, the electrons use the hull as a low resistance path on their way from the boat to port to the boat to starboard?

I don't know how common that is in marinas.

By the way, do you guys know any good books on this? I've read and reread "Metal Corrosion in Boats", but would also like a more step by step type book that applies the theory, like a Compton's "Troubleshooting Marine Diesels" for metal boat owners.

I got the best isolation system possible = No shore power connection. I do not imagine I will stop worrying. Perhaps a suitable medication (Valium?) would solve the problem.

Pro - Dry boat. No leaks. No mold/mildew. No fan/dehumidifier.

Although I rather enjoy the mood altering effects of a couple of drinks, the pain associated with the aftermath (hangover) prevents me for using alcohol in any useful manner. A real shame.

yes it is a shame. I guess I'll just have to drink the one I made for you - Skoal!

Any boat can be damaged by stray current corrosion because the boats have metal underneath the water, like props and shafts.

Good books? Google search, this is not a boat or boating specific question. If you want books, use Google or an Amazon search on, oh for example, "Metal Corrosion in Boats" or "Corrosion in Metal Boats" because there are lots of reads on the subject and not all the skippers reading this may be the ones with experience with that particular subject.

Good luck.

Stu - there's always something known as a "sunupper". Remember, the sun is always over the yardarm somewhere……………….

I don't understand. This is a boating specific question, right? Searching Amazon for the title of a book I've already read just gives me that book, which is good, but in my opinion a bit disjointed for a metal boat owner looking for best practices.

Googling metal boat corrosion is worse than googling boat lightning protection.
