Those of use that have had the mixed pleasure of working as an engineer on yachts will all at some stage have had these things happen when dealing with spares onboard. The boat that I am running at the moment when I arrived onboard I was told had an extensive spares list and that it was well documented. However as I got into running the boat and making stuff work I found that many of the spares were old parts put back into boxes and stored. Now that we have thrown most of that stuff out I am not replacing them, I am taking the policy that in the era of the internet I can find it online order it and have it arrive within a couple of days or with a quick e-mail or phone call to a yacht supplier like National Marine it will be sourced and sent to were ever I am in short order. I carry consumables; filters, pump rebuild kits, v-belts and such like stuff. I have expanded my tool kit and my stock of stuff to make stuff with when I need to get creative with making it happen.
I guess that the spares carried aboard will usually reflect the type and area of cruising. I recall an incident involving a 55m motor yacht, intended for "unlimited cruising" where for almost 2 weeks, there was no air-conditioning at all aboard in sub-tropical temperatures during extended passages whilst in the south-Pacific, with the owner aboard. When the "culprit" (still under warranty), a Ø60cm x 2.5m long seawater heat-exchanger was eventually replaced (not delivered by FedEx BTW), some questions were asked: Instead of 1 single heat-exchanger, why had the builder not installed 2 smaller units...?! As far as I'm concerned, there are far too many yacht builders who operate under the assumption that once the yacht has been delivered and paid for, once the warranty runs out, the owner is on his own. Regardless of the millions that the owner of a custom-built yacht might have spent, anyone who bought a Ford Ka would receive a more efficient after-sales service. The current fad, where large yacht brokers charge huge amounts to clients under the guise of "management charges", in support of the yachts they've sold is equally reprehensible. The personnel that the average top-level yacht broker employs "in order to cut-out the middleman" and expedite parts requests for example, is pathetic. Hell will sometimes freeze-over before you get an answer. That's OK when you're in a shipyard for a 3 month refit I guess, less so if you're at sea. Why don't more of these larger yachts employ their own, dedicated supply-specialists? That could represent another avenue for those yachting professionals lwho wish to leave the "sea-going" industry?!
While we are getting off the original topic, it's turning into an interesting discussion. Very good point, I would be asking the same questions about redundant systems, and if the boat was built for extended cruising why wasn't this thought of. What other major systems had this flaw ? To be honest who would carry around a heat exchanger of that size as a spare. I would also like to add that a good creative engineer would have found another way to provide air conditioning, it may not have been pretty but it would have done untill the correct parts could have been aquired.
It may not be on a yacht but this is my favorite engine room Lets see some more of those shiny engine rooms!!!
Talitha G Talitha G is currently in Hamburg for a 'floating' refit. You can read her blog here :- http://www.talitha-g.com/weblog/ The gist of which is, the webcam has been set up in the engine room to monitor the replacement of her generators stage by stage. This may equate to 'paint drying' for some, but others of a mechanical bent migth enjoy it! The webcam is here :- http://www.talitha-g.com/webcam.php
Maltese Falcon Here's a couple of photo's of the mains on the 'Falcon' I'll post some of the engine room when I can find them
Great to see you are still around Jed. Stewart you got a nice little engine space there, while it may not be big it looks well maintained and clean. At the end of the day thats what really matters.
