I have used many different marine services over the years, some are very good. I would say though, that there are many shonky operators around, and wallet-surgery is ramoant and damaging. Many incompetent operators leave a trail of damages behind, overcharging and bungling in equal proportion.
Consumer Guarantees, for Acceptable Quality, Fitness for Purpose, Repair, Replace, Refund - all compromised because, under the Admiralty Act "repairs or alterations to a ship", which floats on the tides, must be heard in a court. That means delay, coverups, misrepresentation.
I was poisoned twice, by "Sydney's Premier" diesel mechanic, with carbon monoxide. The mechanic, Philip Lulich, has no license, and very poor engineering and managing skills. He claims to have been in the marine industry for ten years, and boasts that he works on the maxi Wild Oats.
I have had an electrician leave behind a battery which was cooking and emitting acid for hours, and lucky i was around to stop it.
Some small marinas are very good, some very bad. Standards across marine services is very varied. Choosing an operator is risky and potentially life-threatening. Plumbers and electricians on land are much better trained overall, the industry is well regulated because it relates to houses. Why are shonky mechanics like Phillip Lulich continuing to thrive, working with poisonous gases not a care in the world? Getting CO2 poisoning on land is unusual. Except with caravans and gas heating disasters..
The Coroner has recommended CO2 alarms as mandatory in small sealable spaces, like in caravans and boats.
Better licensing and regulation means bureacracy sure, but along with that comes definite ways to complain, to ensure there is no compromise any longer, of boat owners' Consumer Guarantees, which are supposedly, after all, non-negotiable.
