Hello. All very interesting. We bought our 40ft NB complete with a four prong foldy anchor and a bunch of chain. Not really knowing much about sailoring and stuff I tied the chain to a longer length of climbing rope with a loop on the end, just in case. For the first three years it wasn't used, then this year it's been handy to have on two occasions. First time was on the River Wissey, going past the sugar beet factory where there is a large fishing lake with 'no mooring' signs all about. So by dropping the anchor, we were able to have a picnic in the middle. I'm not sure if that a bad/naughty thing to do or if it was that an ok thing to do. On the second occasion we were coming downstream from Bedford and were held up temporarily by some bridge erecting works. There was nothing on either bank to moor against and we were told it would be twenty or thirty minutes before we could go through. So a quick donut and drop anchor it was. I like my little anchor, wouldn't want to have to use it for anything serious though...
