Went with Docking by Control out of Florida. Came recommended by my yard manager. So far been great to work with - answered ALOT of questions and made me feel comfortable. They also recommend biggest / baddest thruster you can fit, incremental cost for up-sized thrusters is small when comparing total job costs. I am having the new proportional control RIM-DRIVE Vetus thrusters with 48V battery banks / chargers and dual controls. Boat is a 60,000 lb, Tollycraft 53 with significant windage. Install is scheduled for first week in OCT. Total price not including bottom paint and other work happening at same time is ~$35,000 all in. Florida Bow thrusters bit was nearly $10,000 more for same thing except single battery bank / charger. Will post on how it all worked out!
