I would go for XS if i was buying one...
I thought commercial shipping used both X and S band radar, but with the preference to use X band when closer to shore / busy areas and S band when off shore and "looking further away". So for most RIBs X band is probably 'good enough' - which transatlantic sailors would prefer S (or X&S). Perhaps some of our merchant shipping members will comment on the reality?
