Scott - if you have people rotating in and out...won’t you need to do new tests for every group?

I have pondering this as well since my husband and I have back to back boats booked for June. We will be on a very nice 44 mono for the first week by ourselves - then we move to a cat for 10 days with (hopefully) four more people. I know we will have to quarantine with them but will we need to retest??
