I am trying to create an Excel worksheet that will help me evaluate upkeep costs on different boats I am interested in. I can look up prices for various items and materials online and of course labor will vary depending on how much I can learn to do for myself vs having to contract out. I expect that outside labor should decrease as I learn more about systems and their repair. The question I have applies to how often I can reasonably expect specific things to fail or require attention to prevent failure. With that in mind, let me establish a likely scenario to work with and go from there.
I would be a single live-aboard, primarily coastal cruising along the U.S. east coast from lower Canada to some destinations in the Caribbean. No racing, conservative sailing and assuming typical rough weather events that Iím sure will be unavoidable. As far as the boat, letís assume that everything starts new. I realize I wonít be able to afford that but it gives a relative starting point for equipment longevity. Iím looking for your opinions and experience with reasonable usable life expectancy of these types of gear and equipment;
Ground Tackle, especially chain and nylon rodes
Electrical items like wiring, nav & lighting systems, etc.
Electronics including chartplotter, AIS, SSB & VHF, Radar
Deck gear such as winches, blocks, and tackle
I understand that even new equipment can fail prematurely and unexpected events can damage or destroy even good equipment. Letís face it. $hit happens. I know I canít expect a specific amount of safe life out of all these things so what Iím asking for is a conservative estimate of how long each of these things can be expected to give safe performance under the conditions I outlined above. If you can think of anything I might have overlooked, feel free to add to the list.
Thanks to all.
