The diagram makes it a lot easier to envision but still there are some ambiguities that make it hard to give you the exactly correct advice so take this FWIW. As the 34' came out he was the stand-on vessel and so you needed to slow or turn away. Depending on where the MP boat was and exactly the relative positions of yourself and the 34'-er, you had several options. One was to do what you did and this doesn't seem unreasonable. You also could have continued turning to port so as to allow enough room for the MP to pass btw you and the 34'. Or you could have stopped dead and let the situation resolve itself. If the MP was far enough away you could also have slowed to allow the 34' to pass and then turned in behind him to follow but only if such a manuver wouldn't have put you in immediate risk of collision with the MP. So w/o being there I can't say which is the best option. A good rule is to always act in a predictable fashion so others can figure out what they need to do. The best thing now is to give it some thought and figure out what you'd do in a similar situation in the future (hence your post). I'm a bit curious as to what the MP boat did. He was the give-way vessel in any case and ideally he should have slowed or stopped far enough in advance to avoid further complicating the situation. Was his warning that you were too close to the 34'-er or to his boat ?
