Hi James,
Grind out the V as suggested, it is not a structural change.
Trailing with the rudders on is OK. We preferred not to only they make the boat just that much longer. It is astounding how many idiots will tuck their cars right up between your hulls, at 75mph+. Having rudders seems to invite even closer "drafting" options to people with the numbers '8' or '3' (with angel wings) on their vehicles - if you know what I mean
So a little off subject but about trailing:
We built hangers (using a little angle-iron) for our trailer signal lights, held in place with the rudder pins which put the signal light up high and in the face of drivers behind you. You have to run a ground wire to the lights as well as the regular signal wires, but I had a lot fewer tail-gaters with these.
I have also seen a simple contraption designed to hold trailer-lights hanging under the rudders. That seems like a good idea too for someone like myself who really has become too lazy to pop the rudders off
