I'm sorry, but I have to disagree with this.
A bad owner leaves the service personnel with the cost-free and non-life-threatening options of leaving the job or boat, whereas a poor service provider can cause serious or life-threatening problems for an owner, or the cost of having the poor job done properly.
After several years of using local refer & A/C techs in the VI and having disastrous consequences for my chartering, I ended up flying a tech in from Fla whenever I needed one. Cheaper and better in the long run, especially when the guests are paying upwards of 18 grand a week for an air-conditioned boat!
These days we do all our A/C & refer work ourselves as we just cannot find any competent service providers in that field anywhere in the Caribbean, nor can I afford to fly one down from the states, even if I could find a competent one there, which I doubt.
It's a real PITA, as we must have the gauges, gas and specialized tools aboard for this job. It would be cheaper to pay someone competent rather than purchase and store those things, considering how rarely one needs these units repaired.
We boat owners are at the mercy of the service techs for those jobs we cannot do ourselves, and unfortunately, the internet has not been a great deal of help in weeding out the bad ones. Perhaps this is because so many owners are just clueless these days because they have never had competent techs or yard personnel?
Well, you are certainly entitled to your opinion.
It is not the internet's responsibility to weed out bad service providers any more that it is to weed out bad customers.
On the one hand, I hear some claim "It ain't brain surgery", or "rocket science"; yeah I like that one (even though the work is a craft in a science that is identical to that used on rockets).
And then a few that claim "everything is a matter of life or death". Or that a marine service tech should be as intimately familiar with every aspect of a specific vessel within 15 minutes, as the boater is after 30 years of ownership. But then if the owner doesn't know something they most definitely should, well, they're not the pro.
Seems to flip flop whenever it suits a particular argument.
I agree that an error by a marine electrical tech, an FRP tech, or a diesel tech, could end up being just as fatal as a slip of the knife by a surgeon.
As far as the claim of "no risk to the service provider" well, in my opinion that is just wrong.
Any error a service provider makes runs the risk of damaging their reputation and livelihood.
Not getting paid because an owner is a dead beat.
Invalid warranty claims.
An owner badmouthing a service provider due to the owners own fault.
These are all risks on the part of the service provider. There are many more.
I have to protect myself and my family from a rare bad customer I may accidentally accept.
A good service provider can avoid most of these by screening their prospective clients well, but unfortunately, no matter how careful, every now and again, a bad one will get through. (We have ways of dealing with this, swiftly, professionally, and courteously, like everything else we do.)
