I've been practicing the MOB procedure for US Sailing certification and I'm having a problem judging the boat speed on the last leg of the maneuver. To review the process, it starts with turning to a beam reach 3 or 4 boat lengths followed by a big tack to a deep broad reach then a turn to a close reach to pick up the victim. When I make the turn to the close reach I find it difficult to judge whether I'm going to make to the victim, or if I'm coming in too "hot". I know I can sheet in the main to power up, or if I'm coming in too fast to bear away then quickly turn back to a new approach, but I don't have a feel yet what to implement when and for how long so that I arrive at the "victim" but just about ready to stop. What "cues" do I use to judge my approach speed? Btw the boats I'm using to practice on are club boats not mine, and mostly Catalina 32 or 36. TIA for any suggestions.
