On maps being wrong, light at the end of the tunnel, and in the "Pretty much common knowledge" department...
This morning, while I was waiting for the coffee to brew, I watched a video of a guy with an Oyster go on about various ways of not getting taken to the cleaners and saving money while your boat is in the boatyard. For what's it's worth, his advice was mostly spot on.
Of course, the best way to save money in terms of boat work is to have a boat that does not require the hiring of people to fix it. Or as Lin and Larry Pardey said...
"If you can't repair it, maybe it shouldn't be on board."
The good news is that for the most part, there's pretty much zero rocket science involved in sailboat systems so it's within the abilities of most everyone to sort problems when needful. For those jobs and repairs you don't know how to fix there is always a good book on the subject you can refer to.
On the other hand, since a lot of folks don't like to read, they go to their forum of choice and try to get their information there. Which, considering the large amount of erroneous information I see on the various sailing and cruising forums, might not actually be your best bet and an excellent way to screw up beyond repair whatever needs fixing.
To make things easier to save money on repairs and suchlike, confine the various systems aboard to equipment that is simple and user repairable and where user repairable is not an option (spelled most electronics) choose items that are affordable enough to carry backups for redundancy.
More on some simple user repairable systems and redundancy strategies soonish...
