If you are going to team up with other boats make sure they are matched for speed of running and sea conditions.
As a member of the Association of Dunkirk Little Ships I've made two of their 5 yearly crossings Dover or Ramsgate to Dunkirk. We cross the channel in convoy at the speed of the slowest boat and boy can that be uncomfortable. Lazy days needs a bit of way on otherwise she rolls like mad, at times we're only proceding with engines running at tick over. faces can turn a little green on board.
Though once tied up in Dunkirk faces do tend to get even greener catching up with old friends and having a few.
