Variety is the spice of life! Sometimes I have sailed with less than ideal crews to experience a cool boat. Other times have sailed on a crappy boat cause I knew it was going to be a great party. Other times I knew someone had a need that I could fill so I went with them.
Two guys on the bow with one weighing 250? Very large boat or middle of the pack or worse finishes. Even if the guy changes position he will be the same. He moves to trimming and he will comment on everything the bowman does. Suck it up and get along with him or find a new ride.
My guess is that with just a 5 boat fleet it wasn't worth the time and effort. To me unless your a pro and money is involved, protests are just to work on getting someone you race against often to follow the rules.
