Since I consider power equally as much a part of my cruising as sailing, I want the engine to be as reliable as the rig. Clean fuel, especially in remote areas, is the foundation of that. I'll point out again that this group is rec.boats.CRUISING. It's not a sailing group and it shouldn't discriminate between sail and power boats. If you want to be a sailing purist, go have conversations in a purely sailing newgroup. If you're a cruiser, many times you'll find that either the wind isn't blowing or is blowing out of the wrong direction. As I often say, "The windex points the way" meaning that's the way that you want to go. And many times you can't sit around waiting for the perfect weather window, and as a result you have to motor. There's also a big difference between someone who goes out on the weekend with the boys, bashing along with the toe rail in the water and a cruiser who has their household stored below. I hate pulling in and finding the contents of the cabinets shuffled all around and things in the cabin tossed around. Let's not forget that all important marital/relationship bliss factor. It's very important, especially on a small boat where there's little personal space, to keep the admiral happy. I know very few women who like having the toe rail in the water for any extended period of time. I'd much rather cruise with a wonderful, happy woman who keeps me warm at night as opposed to cruising solo or with a bunch of smelly guys! So to emphasize Roger's statement, engines aren't something that most sailing cruisers want to use on a regular basis, but they're important, as without them most cruisers wouldn't go very far. -- Geoff www.GeoffSchultz.org Both Geoff and Roger make excellent points which jibe with my experience. Of course one of the reasons Wilbur is so fervid about not using power is because he is/was using something like a 10 horse outboard for an aux. No offense intended to others using outboards, but nothing could be more unsuited for aux power on a cruising boat. Small outboards typically have minimal or no alternator for battery charging, burn over twice as much fuel as a comparable diesel, introduce the risks of gasoline storage, have props that are inefficient for slow speed/heavy load operation, and tend to be unreliable in long term service under those conditions. In my opinion outboards are suitable only for day sailors or weekend cruising. |

Real Sailormen do what ever is needed to get where they are going. Always has been that way too. Cheers, Bruce in bangkok (bpaige125atgmaildotcom) |

A mate of mine, coming back from a trip to the W. Coast of India motored for a week to get back. It is all well and good to say that "real sailors sail, but had he not motored he would have got back next year. You see, the monsoons were changing and had he not motored the N.Easterlies would have caught him and that would have been that till next year. Of the blasted trip I just made to Malaysia, helping a friend take his boat down. We had mild weather, "maybe no wind" forcasted and ended up with 20 - 30 K wind and 3 to 4 M beam swell. Then the Main blew out so we are now reduced to a reefed jib, and we were rocking and rolling. Swell and wind on the beam, lee shore with no hidy holes 40 miles to leeward, India to windward and 50 miles north or south to the closest shelter. Midnight, both wives down below barfing and me and Frank in the cockpit hanging on with both hands. So we motored. By the way, for those nautically challenged, my wife says she has discovered a better way of being seasick. Barf into a plastic bag. you don't have to try to hit a moving target when theboat is rolling and the bucket starts slipping and slidding and when you are empty just twist the neck shut and hang on until the next spasm. One good size bag will last nearly 8 hours she reckons. Nope, no motor, no go. Cheers, Bruce in bangkok (bpaige125atgmaildotcom) |

Whoever coined that stupid, inaccurate phrase? It's fuel filtering. Why not call a spade a spade? The saddest thing about it all is how diesel fuel is so unsuited to anything but being burned. It can't be stored for any decent length of time with out growing all sorts of crud. Pretty damned stupid for yachts where it's often stored for month upon months. The only thing more stupid is people who try to make it sound glamorous by calling it "fuel polishing" and bragging about their systems that only indicate they hardly ever sail.

Cheers Martin Just one of a few of Capt. John's misconceptions...... You need to study up a little, try asking your engine manufacturer about those filters. The marine specialist at HO Penn, our local Cat dealer on Long Island, was adamant about this. Said regardless of the engine manufacturer, they specify the 30 micron filters for a reason. Your probably more likely to get away with it with a little sail boat engine than a larger high output engine. For the price of a rebuild, or replacement, I'll take the manufacturers advice over your's and day of the week. Your ity bity KittyCAT Diesels don't even come close to the BIG YELLOW CAT's in my Summer PowerHouse. (2.8 MegaWatts worth) Our CAT Service Folks spec'd and installed MULTIPLE Racor 2020 10 Micron Primary Fuel Filters on the 4" fuel line that feeds the PowerHouse from the Tank Farm. The PowerHouse was Designed by Ed Wahl, one of CAT's most repected Power Generation Engineer dudes, who taught a whole Generation of CAT Field Service Folks how to do their JOBs, being the CAT Power Generation Engineering Instructor, in his later life. If your running your filters until the engine is getting "Starved for Fuel", and "running lean", then your and absolute Moroooooon, (Bugs Bunny Definition) as that would mean that there isn't enough fuel to fully fill the Injectors each time they fire, AND that also means that there would be NO fuel coming back thru the Fuel Return Line, AND consequently No Cooling of the Injector Tips, which is the Primary Reason for the Fuel Return Line, in the FIRST PLACE. Very Good way to BURN OUT the Injector Tips on your CATs, Sonny.... Just where did you learn your Diesel Engineering.... Dufus's R Us??? -- Bruce in alaska add path after fast to reply |

"Fuel polishing??? Whoever coined that stupid, inaccurate phrase?"
The entire filtration industry adopted the term 'polishing' in about 1925. 'Polishing' via a filter means that the filter removes at a maximum 0.05% (by weight) of debris per 99,05% (by weight) of liquid filtered. So, 'polishing' can be be by recirculation or single pass if the removal % is lower than 0,0005. Filtration removals at greater than that .0005 level are called 'depth' or 'cake' filtration - this has been the 'jargon of the filter industry for almost 100 years. |

I drained my primary Racor filter today and have this to report on one of the world's smallest on board fuel polishing systems: There was not a drop of water or speck of dirt in the drained fuel. *It looked perfect. *The 2 Mu filter element was slightly discolored but with nothing visible on the surface and it was clearly not challenged by anything in the fuel. The previously white polishing system filter was a dark grey brown and had clearly picked up quite a bit of stuff. *No visible loading though. This system: http://home.roadrunner.com/~rlma/StriderFuelSystem.htm exceeded all expectations in operation this season. *It's simple and intuitive to operate, works in almost any mode, and was trouble free. *The only change made during the season was to add a high point loop to the common vent so fuel wouldn't flow into the lower tank at large heel angles. The only operation challenge was forgetting to open the main tank valve a few times since I close the tank which can siphon in case of a fuel leak. Fortunately, the fuel pump makes a distinctive clattering when drawing against a closed valve for several minutes before the engine starts to stumble and I can open the valve from the cockpit. The only surprise was the that transfer pump would only suck about 80% of the fuel out of the lower tank when transferring to the upper tank. *Once the boat was hauled, I determined that it is simply because the flow capacity is so high that it sucks air down through the fuel. *With the lower draw of the regular fuel pump, it will draw down to a lower level. *The operational quirk then is that the polishing system needs to be off to use the last of the fuel in the keel tank. *This would be a rare occurrence though since drawing from a tank that low runs the risk of drawing air into the system due to sloshing. This whole system is a testament to the value of a group like this, even for a boat designer. *Thanks to all who took time to discuss it while I was developing it. -- Roger Long In order for "the gumk" to grow in your fuel tank their must be water present, no water, no gunk. This is the main reason it is always reccomended that you keep your tank full. A full tank will not draw moist air into the tank through the vent as the fuel expands and contracts when it warms and cools.If you've got water in the fuel, your going to have some kind of growth unless you treat your fuel with an aditive like Biobor. Filtering it, or as some prefer to call it, polishing it, will remove the growth, but it may not remove the water, depending on how long your fuel pickup is. Your best bet is to treat your fuel on a regular basis, keep the tanks full at all times, and change filters at the first sign of trouble. Polishing is only going to make the problem go away for some period of time, but it will be back. Another point, those 2 micron filters on your Racor, check with your engine manufacturer, I've never heard of one reccomending more than a 30 micron filter as the promary. Using more restrictive filters can cause problems with your supply pump, or, even worse, cause the engine to run lean. That will cause the engine to run hot and, over the long run, cause all kinds of other problems. |
