Hey Considering that you don't know if the rest of your AP system works, I strongly suggest that you buy a new system. I'm really surprised at the cost of the used control head. IMHO it's not worth the chance that some of the older gear won't work. The new gear is modern, will come with all new wiring, an interfaces easily with other devices.
The EV100 should work very well with your 30. If you do sail in shifty conditions you may appreciate the 'sail to wind angle' setting. Note that if you encounter a large wind shift you need to acknowledge the change on the control head. Small shifts are handled automatically Good luck, Barry Barry Lenoble leno...@optonline.net Deep Blue C, C&C 110 Mt. Sinai, NY Hi Barry, I have a C&C 30MK1 - would use it in most conditions and mostly solo sailing where i missed not having the AP the most. Most of my sailing are few hour trips and racing around the bay; not allowed to use it for racing. it is real nice to set when putting sails up, cruising and relaxing, make coffee or whatever. The winds where I sail tend to be gusty and shifty. I don't plan on interfacing to anything else. Perhaps I should think that way i do have a standard horizon cp300i chartplotter and older navman 3100 depth and speed instruments. wind instrument is shot and would eventually replace but for now i don't miss it. the control head has always been missing since I purchased the boat last year I can only assume the other components work. A used 4000+ control head seem to be about $750cnd and the ev1000 will be about $2000 cnd with rebate. I don't like to spend more than I have too but I like things to work as well, tough decision - leaning towards the new one. I really don't think used electronics should be worth that much but they seem to be hard to find and expensive. - _______________________________________________ This list is supported by the generous donations of our members.
