During a survey earlier this month, our research was interrupted by the few words you never want to hear or say on a boat; "I smell something burning!" Monica, our most experienced tinkerer and boat captain, was on watch; I called to her and told her what had been said. She scrambled back from the bow to troubleshoot the problem. We used our noses to try and isolate the source of the burning smell - was it electrical, rubber, plastic??? Kelsey was at the helm and quickly shut down everything electrical- the engine, computer, radar, GPS navigation unit. As we lifted up the engine hatch, the smell became much stronger.

We narrowed down the source of the smell to either the alternator or the alternator belt. After more tinkering and discussion, we realized that the alternator belt was rubbing up against a bolt on the engine. Luckily for us, the weather was very calm, and although we really didn't want to start taking things apart at sea, we didn't want to lose the rest of our survey day to motoring home early, or worse- the need for a tow. As Monica says, there are a few breakdowns you don't want to get towed in for, and one of those is for the alternator belt. Always prepared for the worst, we never leave the dock without a variety of extra parts on board. We found our spare alternator belt and consulted our log book for the details of the last time we had to change the belt, back in 2009. Monica is an ace with a wrench, but had not changed the belt on the Nereid before, and I am an amateur at best with a wrench, but had helped with the last belt replacement in 2009. And so we put our knowledge together while the rest of the crew napped, ate, and/or looked on with

The new belt was fitted into place around the pulleys, making sure that it was well-seated in the grooves. When Kelsey started the engine and revved the Nereid back up to speed, the smell was gone! Everything was working well. We lost just under two hours of survey time due to our breakdown, and although the right whales eluded us for the rest of the day, we were pretty pleased at that our tinkering talents had let us keep sailing for the day.
