I've got an Icom 718. It's a basic
radio but relatively easy to use without many layers deep menus the more modern radios require you to go through. It worked great on the sail to
Hawaii. Mine has been opened up so it is capable of transmitting on all HF frequencies. That's about a 5 minute job for someone with limited
electronics experience. Bought mine used for a little over $400, new ones are around $700.
If I wanted a more complex
radio, would look closely at Icom 7200. It has a marinized front
control panel. A nice to have feature on a boat. Looks to have most of the bells and whistles to tweak the radio for best
reception and
transmission.
