Did you contact the charter company as soon as you discovered for example, that the refrig wasn't working, to give them a chance to make it right, or wait until the end of the trip? How did they respond?
Fair question. No we didn't. Using the freezer/refrigerator as the example, we didn't realize it wasn't working until the second day of the charter. We weren't about to backtrack and spend our precious vacation time waiting on maintenance that should have been done before we arrived. We dealt with each issue and we were able to accomplish our goals.
1. We warned each other when we were going to take showers, to be sure the other one didn't turn off the water pump accidentally.
2. We bot ice and consolidated all the food in the freezer compartment.
3. We fixed the tangled reefing lines.
4. We broiled instead of roasting.
5. We switched cabins.
6. We turned the starboard side of the boat slightly toward the wind when we lowered the sail.
7. We idled the engines at 2100 RPMs (the lowest RPMs where the throttles would stay in place)
8. We learned to control the throttles to keep the RPMs even.
9. The cockpit light didn't really make a difference.
10. We were aggravated that they had marketed the boat as having dingy davits when for all practical purposes that was a deception. We found a spare snatch block on board, tied it to the dingy painter, used a dockline as a rear bridle, and towed the dingy from the centerline of the boat.
None of the issues were fatal, just inconvenient and annoying, but not so big a deal that we were willing to sacrifice our vacation (and objectives) to get it fixed.
