Tell us how you calculated the effects of tide on your course to steer. Tell us how the weather forecast affected your plans. Tell us how the actual weather affected your trip. Did everything go according to plan? Great questions! LIS currents were more of a factor than I anticipated, especially from previous sails. On our return leg, we were slowed below 5 knots which I might have improved on had I sailed closer to the Con. Coast. I often find reduced current there. The weather on friday predicted "severe T-storms" but I knew we could be in a good area to deal with them (plenty of water) and it would be a worthwhile experience. I've never been in a T-storm at night. The storms flanked us with plenty of lightening and thunder, but never came. Not even a drop of rain. By the time we were approaching Port Jeff, winds had come up to around 20 knots + and there's a bit of a confused sea (as our cruising guide warned) outside the entrance. Following advice, we sailed back and forth making sure we fathomed the entrance correctly. Suzanne was doing the nav and having a tough time making sure we had it right. Everything went according to plan accept that we did not know that so many boats would be littering the Thimbles. It was so crowded that we left soon after and grabbed the mooring in nearby Morris Cove. We missed our planned return time at City Island by two hours. RB |

To be more specific, VMG was reduced, but I did not alter course to seek out a less effected track. We were having a fine time, on course and going down the up escalator. RB |

there.
So, how did you calculate the effects of tide on your course to steer? No calculations were needed. The current was on our nose. I chose to maintain course with reduced VMG. For most the trip the wind did all it could to aid us against the current. RB |

"I love it when Mooron gets caught lying! 1) I clearly indicated that I saw few boats, which MIGHT be normal for the area" What a liar you are, taking your trolls to new lows. This is really getting sad for you! The boats at the thimbles were ANCHORED. My reference to "few boats" was to SAILING vessels (that means with sails up, Mooron) of which we saw very few. Probably less than 10-15 actually under sail and it was a clear day. Where was Billy Jane? Capt RB |

Was this what you expected before setting off? (Tidal direction being 180
deg to your course, I mean.) Did your logged speed remain fairly constant (aside from variations due to changes in wind speed)? Yup. Eldridge showed those currents, but I really expected to make a better VMG, for no valid reason! Speed over ground averaged 3.5 to 5.5knots. Knotmeter gave 6.5 to 8 knots. Our average was probably below 5 knots after the third hour, but picked up again at the last few hours. RB |

Excellent... you determined both set & drift as well?? That's not easy on a
current that appears to average at over 2 knots at times. Was the seafloor topography fairly constant or did you compensate for the shallows and surges they would present?

Excellent... you determined both set & drift as well?? That's not easy on a
current that appears to average at over 2 knots at times. Observing the track set on the GPS, sailing on a reach, with 1.5-2.5 knots of current against, we only deviated from our track by about a mile. Once 20 miles of the return trip were under the keel we could see the Manhattan skyline and it became a line-of-site sail, though i maintained a specific (245 If I remember right) SW compass heading anyway.

Actually, some dumb behavior on my part. I failed to put fresh batteries aboard for the the GPS and left the new power cable home. I was "spot" using the GPS by Sunday and I even failed to buy batteries at port jeff! Yes, the small drift was just not a factor over such a short distance. The most I know about the Sound's bottom is that taking more "near coastal" tracks can ease current woes. On the other hand, I was expecting wind direction changes and I wanted more course options afforded by being in the center of the sound. RB |

This amplifies the importance of maintaining a hard plot on paper chart. How did Suzanne derive the cross track?... by hand calc or by spot check interpolation with the GPS? Both methods are suitable.. it's the end results that count. You'll find that current surges are typical on raised or suddenly shallowing seafloor topography where the current is compressed and moves at a slightly faster rate. The reason to favour the coastal [ read shallower] areas when combating current that is against you is that the brunt of the current will favour the deep areas and often you can encounter a coastal eddy that actually assists your forward motion. I would maybe have considered shorter coastal tacks than the long ones afforded by sea room if time was an issue and the extra work involved was not impeding your enjoyment of the sail. You'll find that options always come at a cost and the drift afforded by the selection of open area navigation in a current may adversely affect your ETA. The importance of navigation and it's application is imperative to becoming a sailor. How fast you drive a boat is of no consequence when you don't know where you are going or how you will get there. Keep a log of every trip... it is a valuable resource for future excursions and illustrates a respect and proficiency in the art of sail and seamanship. CM |

Yes, I probably should have headed in for less current, but we were having a grand time. Current ran against us from around 1:30 to 4:30. 245-250 SW was our course, I believe. I have no idea if there's a chart online. I think Maptech may have some freebee charts of the area. Even yesterday, sailing out of Manhasset, we faced heavy current in the afternoon, making our 7 knots into 4.7-5.0 OG. RB |

How does this "amplify" the importance when we were, for all intents and purposes sailing a short line of sight course? We estimated our losses at aprox. 90 minutes and were quite close. For a 55 mile run I don't see the need for more than crude navigation. We know the waters. Next Spring when we do Great Gull and Block, we'll employ a higher level to navigate safely. In one respect, you're correct; the practice is probably worth the effort. Maybe when we sail to Norwalk (a very short sail) we'll plot a series of waypoints, calculate current and play by the book for the practice. RB |

Must be the description of your trip that confused me... You wrote: "Observing the track set on the GPS, sailing on a reach, with 1.5-2.5 knots of current against, we only deviated from our track by about a mile." So you were on a single tack for this portion of the return trip? If you completed several tacks ... how would you calculate the combined drift or set for cross track error.. the changing conditions would not allow a cumulative average unless you did the calcs on paper to derive it. Hence my statement regarding a hard plot. This description led me to believe that prior to the 20 mile leg you did not have line of sight. My apologies... but it seems to read that way.

have line of sight. My apologies... but it seems to read that way. We did not, nor did we face the worst of the current in the first few hours, making our course fairly "true" especially in respect to the distance involved. By maintaining our compass heading derived from the GPS, we barely deviated at all. RB |

" Cross track.. or drift and set are easier to estimate on a single tack and more readily confirmed by bearing bearing fix or in the case of limited bearing targets.. running fixes. How did the Compass vs. GPS bearings compare? Did the discrepancy amount to the Variation and did you get a chance to confirm if the Deviation error made much of a difference? Isn't this stuff interesting.... ;-) CM |

How many hours of contrary current,etc other bull ****
Who the hell cares? Is each time a pleasure sail is made is it really necessary to log every fart, every tack made, every change in wind speed, every tide change? I don't do that kind of log keeping. I'm wondering just how many of this group really makes a log entry and completion of every afternoons sail around the Bay? I DON'T. I don't really keep a running log of a simple overnite in my immediate sailing area. I enjoy sailing! I hate paper work! Keeping a running log is dumb paper work. If you like doing it, then by all means do it. I think of all the millions of useless logs recorded on private recreational boats is something that is over done. I'm not a good log keeper. My log has more entries this season with less sailing than I can ever remember. I logged the date of the new bottom, the new main and the changes made because of it. Even at that I'm not sure I haven't over done it? My filed copies of the paid bills are more necessary than the log. You pencil pushers enjoy your log duties.

"Thom Stewart" wrote in message ... How many hours of contrary current,etc other bull **** Who the hell cares? Is each time a pleasure sail is made is it really necessary to log every fart, every tack made, every change in wind speed, every tide change? 16 years ago, I set out on my first sea voyage. I was in a power boat that was capable of doing 39 kts - according to the sales brochure. The trip was from Chichester to Bembridge, and the distance was 6 miles (IIRC). I spent hours, if not days, planning the trip. I worked out the tidal stream, magnetic variation and our course to steer. I tried to plot a position every 10 minutes(very difficult on a power boat that is bouncing along at 20 kts). Visibility was poor (1/2 mile). I cannot describe the pride that I felt when the Bembridge Entrance marker appeared less than 100 yards off our port bow. For the return trip, I didn't bother to do a passage plan. I simply reversed the course. We ended up 4 miles west of Chichester entrance. That was on a 6 mile trip!! Variation accounted for an 8 degree error and the tide did the rest. Bob claims that he has just done his first 50 mile trip. I would suggest that there is nothing in his posts to suggest that he has just navigated 50 miles for the first time ever. My first cross channel trip (75 miles) involved days of planning. Now I do it in 15 minutes max. You have many years of experience, and therefore feel confident at sea. Bobsprit has never undertaken a long trip before, and therefore would do a lot of planning, if he were the skipper. Let's face it. If Bob actually did do the trip, then he wasn't the skipper. I don't do that kind of log keeping. I'm wondering just how many of this group really makes a log entry and completion of every afternoons sail around the Bay? I DON'T. I don't really keep a running log of a simple overnite in my immediate sailing area. I enjoy sailing! I hate paper work! Keeping a running log is dumb paper work. Your comments are absolutely correct. I don't keep a log when I am sailing in the Solent. However, Bob was describing a big adventure to a destination that was well outside his normal cruising grounds. Regards Donal -- |

That's just misleading Bob.... here is an example of some discourse from the thread: CM - H-m-m-m-m 11 hours with an estimated 1.5 hour dinner break for a total of 9 and a half hours of sailing. That would be what.. about 40 miles for your boat? RB - "This one's too silly to answer. Trying to figure a distance travelled based on the time?" CM - that's a silly response.. with a hard beat and current you could have covered a linear distance of 20 miles with a distance over ground of 40 miles. RB - "If you don't know the conditions, currents and so on, why guess at all? You silly" I didn't realize you were so sensitive Bob! CM |

Let's face it. If Bob actually did do the trip, then he wasn't the
skipper. You're right! Suzanne handled most of the Nav stuff. I had the GPS in my pocket and steered like a bus driver. She pointed right and left and I followed. Seems to work! RB |
