Most smart phones have a built in GPS receiver these days, and there are some very decent charting packages available. For about $25 to Navionics I have a full set of US and Caribbean charts on my Galaxy along with a fairly decent little plotting application. You don't even need a cell phone account to do all that, a WiFi connection will suffice. I got ripped off, then. I just bought a Navionics Gold US and N Bahamas (no Caribbean charts) on a little SD/microSD card for my Lowrance iFinder H20 hand-held chart plotter and it cost over a hundred bucks. But, I'm sure the Navionics Gold SD charts are way more detailed than what Navionics offers for that Samsung cell phone. Not to mention the plotting function on the Lowrance is probably way superior to some cheapo cell phone plotter. I often marvel at how some people operate fifty-foot motor yachts worth a million bucks and hanging off the bow is a 30 pound SS Danforth - in other words, all show and no function. So why does somebody with half a million dollars worth of motor yacht justify using a cell phone for navigation?? But Gregory, a 30 lb. danforth will hold a boat perfectly well. It depends on the anchorage and the weather and water. -- Cheers, Bruce in Bangkok |

Myself, I'd rather rely on using an anchor that is appropriate for the heft and windage of the vessel. For a 70,000 pound trawler, a 45-pounder would be the absolute minimum. Even so, I'd be sure to use two of them Bahamian-style so I could feel secure through most any normal weather. (Not talking tropical storms here!) Tell me, please, do you set an anchor alarm on your GPS? I bet you do? If so, then that pretty much negates your feigned confidence in your undersized day anchor. And, besides, a so-called day anchor is a rude operation. You said yourself that you put out lots of length (scope). If the water is 20 feet deep that means you put out at least 7:1 scope or close to 150 feet. That means you swing a very large circle and might get too close to those who use a larger anchor and more conservative scope. Unless it's all chain, that also means possible chaffing snagging and abrasion on coral heads and sharp rocks. And you stink-potters wonder why we sailing seaman don't want much of anything to do with you? I wonder why? -- Sir Gregory -- Sir Gregory |

We would also but were doing race committee duty at Key West Race Week at the time and rapid anchor retrieval was a requirement. I was surprised at how well the Danforth held out there in Hawk Channel on a *very* windy day. Hawk Channel has varied bottoms. Some sandy patches and some hard, rocky areas. If you drop anchor in a sandy patch it will hold well until you get a thunderstory with an 180 degree wind shift --- then you have to HOPE the Danforth will reset. Danforth's aren't noted for reliably resetting themselves as I'm sure you know. That's why I prefer two anchor laid out Bahamian Style. That way no matter what the wind does the anchors keep pulling against each other and don't have to trip over and reset. But, two anchors would never do when fast anchor retrieval was the requirement. For a 70,000 pound trawler, a 45-pounder would be the absolute minimum. Even so, I'd be sure to use two of them Bahamian-style so I could feel secure through most any normal weather. (Not talking tropical storms here!) Tell me, please, do you set an anchor alarm on your GPS? Absolutely not. We back down hard with a pair of 30 inch, 4 bladed props. If the anchor holds with that, it will hold in up to a full gale. Unless there is that aforementioned strong windshift . . . I bet you do? If so, then that pretty much negates your feigned confidence in your undersized day anchor. And, besides, a so-called day anchor is a rude operation. You'd bet wrong. C'mon? Not even at night? I find that difficult to believe. -- Sir Gregory |

Get a clue, dock boy! If you had a BILLION pound ship but no wind or current you could anchor it with a ten-pound rock and it would stay put. -- Sir Gregory |

Bruce, how come you often argue like a girl? Like a girl, you don't seem capable of embracing an absolute that demonstrates a point and demonstrates it well. A billion pound ship that can be anchored by a ten-pound rock is an absolute that proves it's not the tonnage that drags anchors but the force of the wind and current acting upon that tonnage, which is represented by surface area upon which the wind can act, that causes anchors to drag. This all goes to prove that your assertion that one requires X pounds of anchor to properly anchor XY pounds of vessel is deeply flawed. It's a flawed formula because as I have proven, using an absolute, that it's the windage that matters as much or more, in real life conditions than the weight and your dumb formula complete ignores the wind and windage. In other words, you tried to sound like an expert but you failed. -- Sir Gregory |
