Apologies in advance for more questions - I just can't help myself
1. We went out again yesterday - Chichester Harbour across to the IOW and back - fantastic
. We had the boat planing for most of the way at 20 knots. So once you have the boat planing is there any value in increasing engine power (apart from going faster) as this is the most fuel efficient point of the RIBs performance?
2. It was a great feeling skipping across the tops of the waves and only when we slowed did we feel the swell. Should a RIB be planed regardless of wave conditions - I think what I mean is - assuming the skipper is competent (I'm not yet!!) is the safest use of a RIB to be planning or if the weather is bad then going over/through the swell/waves is the safest option - does that make sense??
3. Does anyone know much about the Yamaha Pro engines - ours seems very reliable (75hp) but more fuel hungry than we have experienced with our four stroke 60hp. I'm sure there are lots of threads working through fuel consumption but is there a simple formula to work out fuel capacity vs distance or do you need to try it and see then work out an average yourself?
4. Last question - honest. Some interesting MOD activites going on while we were off IOW - first of all a ship let of a large white smoke flare, a Sea King helicopter (I think) then arrived hovered and the smoke instantly stopped. Next the Sea King appeared to "land on the water" or at least it's wheels were touching and finally we watched to Lynx helicopters patrol the same area. We were to far away to see markings clearly or actual activity. Any ideas what they were doing/practising?
Once again thanks all
