Using Yaesu 6X-R with channels

I bought a Yaesu 6X-R radio. I think I've bought a radio that is beyond my needs.



When I go paragliding or fishing, people want me to to put the radio on channel 1 or whatever.



I can't figure out how to do this. I looked at a maritime channel frequency chart which says:

Channel: 01

Ship transmit: 156.050

Ship receive:156.650



So my question is as a total beginner, can I use the radio to simply communicate with others on channels? How do I go about programming the channels in? What about the different transmit/receive frequency?



I appreciate any help. I should have bought a simplified radio.
