I think Tim nailed it, but almost regardless of what someone gets paid, the "save money" assumes that a "pro" as you called it, is actually available. Many, many, many of us, have, for years, bemoaned the sad state of "marina technicians" and I personally have called the phrase "diesel mechanics" an oxymoron. They are few and far between. Those of you who have found good ones? Keep 'em! And let us know who they are. Same story here for surveyors. I know of only two "trusted" boat electricians here in the entire Bay Area.They've just never taken the time to figure it out, and just assume that doing the work themselves will "save money."
Granted, this doesn't take into account the people who do the work themselves for other reasons, such as wanting to learn their boats inside and out. That's a different subject.
And, just like "at work" when something isn't done right, it takes more than twice the time to fix it. I once had a "boat mechanic" run some hoses for me (until I learned to do it myself) and he insisted that he put a LOOP of hose into the muffler from the exhaust riser even though I told him I had a hump hose and that's what I wanted him to use. Within a month that loop has started to chafe on itself, and I had to do the hump hose myself, anyway!
I had a rigger put on our new ProFurl about ten years ago. Two weeks later I couldn't get the jib down. I called the yard and they sent that same rigger down. He got up on the pulpit and said: "The ********* who put this on didn't use Loctite on the threads on the extrusion." Inasmuch as he was that ---hole, I almost pushed him off the pulpit, but that wouldn't have helped getting it fixed. Maybe he didn't recognize the difference because the boat was in the water...
I believe the more you know about your boat the better off you are. It's a SAFETY issue if you think a bit about it. For the weekend-only recreational sailors who "depend" on SeaTow or Vessel Assist, maybe they can justify their income vs the cost. But for a majority of us who like to venture and stay out longer, and who have serious interest in the overall "How It Works" approach to things (which is where a lot of questions on this and other 'boards come from to begin with), I find it hard to justify having to pay someone to do something that I have to fix anyway.
Sure, there are things I'll let the yard do: bottom paint and rigging.
That's all.
Over the years I've redone our electrical system. I am currently replacing our hard-to-get-at hot water heater and hoses.
A few years ago our engine wouldn't start, no noise at all from the starter. I knew exactly what it was and just wiggled a cheap fuseholder that I had previously moved from a "hidden" spot to an easy to reach location. I knew what was happening. How many questions do we get on this board like, "My starter won't even turn over and my batteries are just fine, what do I do?" If I had $75 for each of those questions...
And, finally, take a look at this entire thread. The first response from most of us to the OP was to suggest that she consider doing a lot of the work herself, and explained why.
Good question, thanks for raising it.
Your boat, your choice. :dance:
