High winds continued, and except for a few days of lighter winds, have picked up again with another giant cold front (that's 75 degrees down here;-) ) passing over us last night. Every morning at 6:30 we listen to the master of Bahamas weather, Chris Parker, on Single Side Band (like ham radio for sailors) 4045kh upper side band. He comes in loud and clear and gives the overview and day by day forecast for the northern, central and southern Bahamas for the next six days. So we don't need Internet access to get the weather - we receive Chris wherever we are.
Anyway, Chris says he can't remember such a steady march of cold fronts and strong north winds, now lasting since we arrived in Florida on October 21. Just our luck! But we've made the best of the weather and since arriving in the Exumas have been able to sit and relax in quiet water, getting in to "Island Time".
On the 19th it was time to recharge our batteries as we'd been parked for so long without running the engine. We have a nifty diesel generator on board which we can fire up whenever we need to charge the batteries. It sips 1/4 the diesel that the engine takes (about 1/4 gal per hour) and is quiet compared to the main engine. We can compensate for two days operating just on batteries by running the generator for 2 hours. j
ANOTHER MECHANICAL OPPORTUNITY (you can skip this part if you're not into boat mechanics) About 5 minutes after starting the generator it shut itself down. This is typically due to overheating due to lack of circulating sea water through the heat exchanger (like the radiator on your car). And as we've learned all to often this is usaully caused by worn out rubber pump impellers (you've seen past postings discussing these vital parts). So I tore the sound shield off the generator and inspected the sea water impeller. It was in great shape as I'd just replaced it this spring. The cover plate seemed a bit loose, however, so I put it back on and tightened it down. A loose cover plate can cause air to leak into the pump and break the necessary vacuum.
This completed I fire up the generator again with great confidence. Another 5 minutes, it shuts down again. I open the end plate of the heat exchanger expecting to find old impeller blades like I found on the engine. It was clear. I disconnected the output hose leading from the heat exchanger and turned the generator over -- gushing sea water. So the problem turned out to be on the "fresh water" side of the cooling system. There's another pump with another impeller which was in bad shape (see pic). So I installed a new impeller and again, with great confidence, fired up the engine.
OFF THE MOORING HEADED SOUTH. On Thursday the 2oth we dropped our mooring and headed down the chain in amazingly calm conditions. We stopped at Bell Island and snorkeled the wall off O'Brien's Cay. It's called the Sea Aquarium - and for a good reason. ItThis has to be the most spectacular reef we've ever seen diving. As soon as we slid off the dinghy into the water, hundreds of sergeant major fish were swimming with us, passing very close and filling up the vision from our masks with fish only inches away. The coral dropped from near the surface all the way down to 25' deep so there was a great 3D wonderland spread out before us. South of Bell Island there was a tricky tight passage down to Pipe Cay and Compass Cay where we bumped bottom twice. Fortunately it was mostly sand and no harm was done. We anchored in an isolated spot for the night.
On Friday, another beautiful mild day, we took the dink into a small marina on Compass Cay. Instantly we were surrounded by nurse sharks and other fish - obviously trained to expect food handouts. We wanted to stop here because we'd read wonderful things about the Bahamian guy
Now we're anchored off Sampson Cay in a tight cove which is protecting us from yet another cold front with its 20-25kt winds (30mph). More reading, relaxing and catching up with the blog. Last night we took advantage of the nearby restaurant by taking the dinghy in for supper. We were the only people eating so we had a great time conversing with Anishka, a gal from Nassau who has worked at this upscale resort for two years. She told us a lot about Bahamian cooking and spices used. And also how they prepare the resort for hurricanes.
