stainless feasability

[orangutang]

i'm just an armchair yachtie but i'm curious as to what length a cat needs to be before stainless steel become feasable with cost and weight etc. i imagine it lies somewhere around the 14m mark. has anyone ever done the mathematics. is it a material that will have its day eventually? has this question been done to death before?:?:

i hope stainless has its day, because it has the one thing we need from a metal, the ability to not rust ,even tho its ugly, however, until they make it without it being brittle, it is not safe-signed winjin pom

Stainless is poor choice for hull construction.

Have a look into Cupronickel if you are seeking never ending durability (with the associated budget!). Titanium and Monel could also be possibilities.

I would prefer marine aluminum over stainless.

I would prefer marine aluminum over stainless.i should have mentioned cost, if it was no problem i'd use ali/bronze

Most stainless suffers from corrosion when it isn't exposed to oxygen. Hence stainless is not a good choice for submerged portions of a hull.

Conventional steel has better properties for boatbuilding than stainless.

true , i should have said s/s for fittings , corten steel or mild steel is fine for hulls
