We put Raymarine instruments on our 30U. We have a 9" Axiom MFD, AIS, a triducer for depth, speed and temp, an i60 for wind and an i70 for whatever we want. Love it all except for the i60 and the triducer. The triducer has a paddlewheel for the speed - need to pull and clean it too frequently for my tastes (and we normally sail 3-4 times a week). Look into the one that works on bubbles (or whatever). My wife loves the AIS - it is great to know the commercial vessel approaching , especially at blind curves.
The i60 has never worked properly. We get weird readings - jumps from 12 kts to 60 kts, for example. Raymarine has never been able to figure it out. The wind instruments totally stopped working earlier this year but the day we were to leave for a one week cruise, as we approached the boat an osprey took off from our wind transducer. It has appeared to worked ever since. I have not figured out how to pay the osprey for services rendered . . . .
