I'm trying to find out about this VHF radio I got with our boat. I can't find a brand name on or in it other than the Mariner 7800 name on the front. Picture attached. Also trying to find out exactly what the difference is between our boat (1979) Buccaneer 22 and the US Yachts 22. Where can I get the specs and photos for both types of boat? There was a link for the US Yacht 22 but it wouldn't show anything, just a blank page. I've been told that the boat I've got is also known as a US Yacht 22, designed by Gary Mull. Same hull but different rudder. Help? Thanks
