I used to use a GPSMap60CS, but the handlebar mount did not hold up well on the bike. I have used the Garmin Edge 305 on the bike for years and loved it as a bike computer - it had no maps. I recently upgraded to the 800 touch screen model with map display and it is awesome. Very easy to load in routes generated on my computer as well. That said the 62 sounds like an updated model of my 60 and should handle your tasks easily. I don't know if they changed the garmin bike mount for it. The one for the 60 was a plastic cradle that would crack after a while. While I love my new 800, the screen is on the small side compared to my 60. As for marine use I put my 60 in a waterproof case when I take it out in my kayak.
