ocean crusing & anti collision tactics....
Hi Rich (that IS your first name, no?),
In foul weather and when nothing comes on the screen I run the radar with intervals of 15 minutes (range 25 sm) to reduce power consumption. In good weather I just have it on standby at nights. Doesn't use much (dunno how much eaxactly this minute) and it saves me 2 full minutes warming up time when I need it fast. My radar is not that modern but it's a big mother, Simrad-Anritsu. Doesn't put out nmea of any kind, doesn't have marpa or all that. So you see why I'm happy with the addition AIS gives me. I take it you go singlehanded? We (the admiral and me) run watches of 3 hours. To be sure we use the old eggtimer for the next lookout and screen-study... Never felt the need for an auditive alarm other than my anchor alarm... But there surely will be nav software around that get's you awake when it calculates (a risk of) collision course from the AIS data... I can ask my dutch sailing computer club if you like...

"I "only" installed an AIS receiver where the AIS transponder is getting cheaper and almost reasonable. I bought the nasamarine engine thats connevted to a serial port of my pc. Together with SeaClear nav software the system is complete and functions well. I see my map, my own position, others together with the info I want presented" |
