Just as bow and stern thrusters allow yacht brokers to say its so easy, just like parking a car which then allows them to sell an even bigger boat (that is way more expensive) to someone with no experience at all. Obviously this is not good: screws and anchors are vital to structural integrity and with the screws corroding, it could lead to structural failure. Making use of corrosion-resistant connectors: When joining two dissimilar metals, such as in cases where copper is used with iron pipes, its better to use a soldered or brazed joint instead of a threaded or mechanical one since the former is more durable than the latter. Not to mention the ugly rust trails and white corrosion that will bleed down the skin of the building as the metals corrode. Stainless Steel is Stain-Less not Rust-Proof and if neglected in a salt water environment, it will corrode! This is why all the wood trim has been removed and yacht decks are completely covered in slick gelcoat! If you take all the brightwork away, there wont be anything shiny on the boat and you wont catch the eye of potential buyers. props. Galvanic corrosion can occur when stainless steel is combined with a more anodic metal, such as carbon steel or aluminum. 316 does a bit better when Cl ions are present, even tho the Cr is less. I would put connect it in my own boat but it would be worth checking after the first season and occasionally after that.
