From there we'll work our way south to Martinique and St Lucia in the Windward Islands before turning around and heading back north. Some of you will remember that we did mostly the same trip 3 years ago. It was arguably one of the best boating cruises of my lifetime and hopefully this one will be even better. Anyone who wants to keep track of our progress or lack thereof can keep track of us he http://share.findmespot.com/shared/faces/viewspots.jsp?glId=0utTAiadygIUkT4LIXeoYfKADAn2Dkz os Right now we're headed to Key West for a few days of watching my oldest son racing sailboats in the annual Key West regatta, and after that we'll head over to the Bahamas and start working our way farther south as weather permits. We'll have some internet access along the way but not everywhere, so play nice in the meanwhile and try to think more about boating and less about politics, gun control, abortion, etc. ======== We've made pretty good progress so far (presently at Chubb Cay in the central Bahamas), and have had some interesting experiences along the way. On day 2 we were heading SW from Marco Island towards Key West in strong north easterly winds and 3 to 5 foot waves - not exactly idylllic, but since we were headed downwind and surfing the waves, fairly tolerable. Next thing I know an 87 foot Coast Guard cutter with a pair of large machine guns on deck is pursuing us from astern. They already had an inflatable and boarding party in the water so it was clearly not going to be a social visit. The inflatable could not keep up with our sprightly 9 knots so they radioed us to slow down to 5 knots, which we did of course. We were boarded by 5 heavily armed young coasties who announced that they "wanted to see if we were safe out here." The boarding officer was almost apologetic but said that we were the only boat out that they had seen. We've been through this before so all of our equipment was well in order, then they asked for our boat documentation and "identificaion for everyone on board". Since our passports were with the boat doc, I handed them in thinking there could be no better proof of citizenship and ID. It turned out they wanted driver's licenses however so they could run a search on the NCIS database in the hope they could find unpaid parking tickets perhaps? It was tempting to tell them that we didn't need drivers licenses to be out there but discretion overruled that impulse. At any rate we finally got a clean bill of health and were on our way. Yesterday while heading across the Gulf Stream from the Florida Keys, we were startled by the sight of a 25 to 30 inch fish which jumped high in the air, even with the flybridge at about 15 feet, and sailed clean across the boat to the other side. It was the most spectacular jump I've ever seen from a fish that size. The weather has been good so far and tomorrow we are headed south east towards Nassau and he northern Exuma Islands. All systems are go - especially the alternators thanks to Tim's good work. ==== Just arrived at South Side Marina in the Turks and Caicos after a moderately challenging run south from the Exuma Islands. We'll probably be here for 2 or 3 days while we rest up and plan out the next leg of the trip, most likely the Dominican Republic or possibly all the way to Puerto Rico if we have a really good weather window. We caught a nice Mahi Mahi about 20 miles SE of the Exumas and promptly cooked it up for dinner that evening. Delicious. http://share.findmespot.com/shared/faces/viewspots.jsp?glId=0utTAiadygIUkT4LIXeoYfKADAn2Dkz os Awesome, I looked and the marina where you are at has a website!! http://www.southsidemarina-tci.com/index.html === Yes, South Side Marina is an interesting place, sort of an international cross roads for boats cruising north, south, east and west. Unfortunately Simon Anderson and his wife are not here this winter. They are incredibly helpful people who were always ready to round up local resources and provide transportation when needed, not to mention their party organizing and restaurant expeditions.. |

Lew ==== I believe it is this one if my memory is correct: http://www.prestolite.com/pgs_products/specs.php?item_detail_id=951&item=A0014867JB&produ ct=Alternator It turns out that you can buy them on EBAY for halfway reasonable prices (search for Leece-Neville 270 amp). It was an interesting project which required a few iterations to get it right. Knocking on wood, it seems to be doing well. The idea was to be able to generate enough DC amps that I could drive a 2KW inverter while underway and eliminate the need for running the generator in most circumstances (the exception being air conditioning). Here's my original posting on this effort: Those of you who followed along with the updates from our Caribbean cruise earlier this year (2010), may remember that we experienced some alternator issues along the way. This was disappointing for a number of reasons because we had already spent a fair amount of time, effort and boat bucks trying to find a high output alternator that was also durable. Our goal is to not run the generator at all when under way, and to minimize generator time when anchored. The potential savings on generator fuel and maintenance add up to a big number. To that end we've installed a 2,000 watt inverter and a bank of 8 golf cart batteries with a total capacity of about 1,000 amp-hours. The inverter and battery bank work well together but the batteries eventually need to be recharged, and when underway, the alternator needs to supply inverter amps, recharge amps and onboard house loads like navigation equipment, lights, auto pilot, engine room blowers, etc. Peak alternator loads can easily approach 250 amps and average well over half of that. To make a long story short, no automotive alternator that we've tried has been capable of these loads over a long period of time, even those that have been beefed up with heavy duty components. We burned out a total of 4 over the course of 6 months in the islands. Repair and replacement was problematic to say the least. After consulting with Tim, our cheerful, ever helpful, resident alternator expert on "rec.boats", and a number of other sources, I decided that a fresh approach was needed. Enter a company called Leece-Neville, a division of Prestolite, that has been making heavy duty alternators for a long time. LNs are used all over the world on fire trucks, ambulances, busses, big trucks, heavy duty construction machinery, etc. Their big alternators make everything else look like a toy, weigh over 35 pounds and are priced accordingly. Many of the really big ones are north of $2K at full retail. Thanks to the internet and EBAY however, they are now becoming available at more reasonable prices. I was recently able to buy a unit that had been remanufactured to like new condition for about $400, a bargain compared to some of our previous repair/replace experiences. It is rated at 270 amps continuously at high temperatures, and is designed for fire trucks, ambulances and busses. http://www.prestolite.com/pgs_products/specs.php?item_detail_id=951&item=A0014867JB&produ ct=ALTERNATOR There are some downside issues however: It is designed for a so called J180 mounting bracket; requires multiple drive belts since it can use as much as 6 or 7 horsepower; and is not ignition protected for gasoline engines. Ignition protection is not an issue for our diesels, and fortunately the front pulley on a Detroit 6-71 can accomodate up to three belts. The mounting bracket was problematic however since the existing mount was for a Delco 2 inch foot. In exchange for a sizable boat buck fraction, a local machine shop fabricated a custom made J180 bracket from 1/2 inch cold rolled steel. In combination with some Grade 8 steel mounting hardware and a new adjusting arm, everything is now solidly attached, lined up and looking good with 3 brand new Gates Green Stripe belts installed. In testing it has put out well over 200 amps while maintaining reasonable temperatures. Stay tuned for the long term durability reports... :-) New alternator and bracket prior to installation with a beverage can for size reference: http://img140.imageshack.us/img140/3557/preinstallwithnewbracke.jpg After installation, with new HD belts and adjusting arm. The black detritus in the background is left over from the many previous alternators and belts which gave up their lives in that spot: http://img16.imageshack.us/img16/1462/installedimg0573.jpg Notes: 1. The washer stack shown in the pictures has been replaced by a solid steel spacer. 2. It turns out that the 1,000+ amp hour battery bank looks more or less like a dead short to the alternator and the resulting load is capable of burning out even a 270 amp heavy duty unit. This could have probably been remedied by installing an external "smart" regulator but it was more expedient to use a 12 ft length of #4 cable as a controlled resistance in series with the house bank. 3. We have now logged about 400 hours of underway operation with this configuration and it seems to be working well. |

The key is to have double or triple drive belts which most small engines are not equipped for. Another issue is the alternator mount and adjusting arm, both of which need to be quite rugged. |

Excellent, Wayne! === Tim, I'm pleased to report that "our" alternator is performing flawlessly so far. *Admiral Diane has prepared a number of meals while we were underway without using the generator at all, just the juice supplied from the big Leece-Neville to power the stove top, microwave, toaster, etc. *When we finish a days run the big house bank of golf cart batts is always fully charged. * That has cut back the need for generator run time a great deal. Oh how I love the idea of massive armies of electrons flowing at high speed, AND in proper accordance! Nothing like a little resistance to heat things up ![]() DON"T SAY THAT!!! Indeed! Maybe you should contact Boeing and give them some pointers on battery management for their Dreamliner. LION batteries have always had an issue with heating up and blowing apart. |
