I've searched all the official Belize government and tourism web sites that specify fee, regulations, and requirements. I find no mention of such fees - what is the source of your information?

The fees you describe would be contrary to their long history of encouraging tourism. Belize has always been known as tourist friendly. They have the most relaxed and best tax and immigration policy for US Citizens of any Central America county.

Could the fee be just a typical cruiser net rumor or myth?
