50kw!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
No wonder most of the old fishermen I know look like they've had their brains fried!!
Not suprised that many boats have a radar arch several feet above head height after being told this. Never really crossed my mind until I started enquiries.
Would be very interested to know how you get on with the PC navigation software for the Raymarine and how you find the onboard navigation of the unit. I like the Garmins coz I've always had them and know how to use them quickly as they are quite intuative, something that's useful when picking up a new boat and sailing across the channel the next day!
