I believe there is room for one skipper at a time. If there are two skippers on the boat then both have to be able to follow orders without a debate or theres going to be problems to follow for decades...I know from experience. I lost a very good friend because I gave an order he didn't agree with. When it proved to be the best decision he wouldn't admit it and never spoke with me again. [I never said I told you so] He actually sold his boat so he wouldn't have to compete against me. Seemed ridulous to me because neither one of us ever won a major event...but he still refuses to have anything to do with me 30 years later.
