Can you enlighten us? Well, sometimes I am surprised too! In this case its worth noting that it is a very familiar route which though 5 1/2 miles off shore open water paddling is one which I have been paddling since 1975. As a result we tend to have a very good idea of the best time to go and also the course to steer. That doesn't mean you ignore the chartwork and most messups have tended to happen when people just treat it as a jolly jaunt. This is what happened to the group I mentioned last time. They got off the end of the breakwater and then tried to work things out from there. Not a good idea. you get a feel for the area and also we have a pretty good idea of how long we should take-usually 1 hour 40 is a normal crossing in nothing above force three providing its not a headwind. Then obviously you reconsider the whole idea if its dark or poor vis of less than one mile. As you get near to your eta then I keep a look out for changes in the water, a sign of rocks below. Any pot marker bouys also give us a few clues because they tend to be placed at the edge of the reef. they also give me an idea of the tide stream. Often we get more hassle paddling in good vis when you turn too soon for the islet and the huts on it. Then the stream pushes you North west. If you mess up and get pushed north west then its a case of identifying the rocks such as the gros Tete which also can be a good spot to sit in the eddy. The problem J and the others had was that they did bump into a rock but could not work out which it was. J now thinks it was gros tete which would be about right as it would have put them about half mileish west of Marmotier islet. Alternatively you sit and wait for a while for the tide to drop a bit mor to uncover more of the reef. At night and in good vis though there are no lights on the reef you will find that the big light on Cartetret will be lost behind the islets as you get within the last mile. Being 7 nmiles distant you can get some nice transits on the lighthouse and radio masts and village lights. One paddle in poor vis which did not go to plan was a 12 mile paddler to the huts on Les Minquiers reef south of Jersey. Again cross tides. Again we have done this quite a few times over the years. On neaps max rate is 1.5kn while on springs its 3.5kn. work to eta of about 3 hours. In this case it was neaps and flat calm with a force 1 easterly. In this case we ended up virtually due south of our departure point and about 2 half mile from target. What seems to have happened was that the wind cancelled out our drift. Its not something I experience often. When paddles in poor vis get problems its often when we leave at unusual times rather than the old tried and tested times. One return from the Ecrehous was made early to get away before the weather got worse. About three miles from Jersey we lost the island. Pete was going down with a flu bug. Though tide was running east a couple members of the group felt sure we needed to head further east after a while when we did not see land (vis we later discovered was less than half mileish). Two of us had got a quick bearing on a bit of the island before it vanished. From this we were therefore able to argue quite convincingly that there was no need to make a big change to our route. In fact it was a good thing we did not change course as our paddling speed dropped due to Pete being unwell and we took nearly twice as long to get ashore. In doing so we were pushed further east. Following the others ideas we would have completely missed the island. It does illustrate how handy it is to have deck mounted compass and also to be constantly observing where you are. Personally I find it stops me getting bored. JB and Gary did a mamoth 23 mile trip to the Roche Douvres light leaving from the Minquiers because the stream are more behind you. The light is 60metres high, but they only saw it after about 2half hours of the six hour paddle. They used gps but only to validate thee course every hour. The return was done in the dark and they reckon this was the hard bit. The high tide ment all the rocks at the Minquiers were hidden and with no moon it was hard to decide where they were. Again based on time they knew they must be near the islet. When they used the gps it was more of a pest because whenever they were not headind directly for the target for the last mile or so the unit was telling them to make big course corrections. Careful planing and good communication between both of them helped a lot. After all two brains are usually better than one. Many years ago my father was fishing about 2miles offshore from his double Klepper. Fog came down. By looking at about one foot above sea leveel he found he could still see land. Just as well as he had no compass. Regarding the "white out" sheet idea. Yes it is disorientating, but then again so can paddling in fog or at night. Even trying it for just a short time can be a good way of getting a feel for what it might be like in poor vis. You could think of it as being an extreeme experience which at least gives you a tiny bit of reassurance when you do get caught out that at least the disorientation is slightly familiar to you. Alternatively, some of the ideas I mentioned might make you stop and think twice before going out in poor vis or at night. Another idea is to go out with a few pals on a nice day and having done your chart work beforehand. Now totally paddle by compass the route you have laid up. Add some incentives like the loser having to buy a round of drinks. Sorry to go on a bit.
