We are looking to get a 400, 420 or 44 sedan bridge. While I had 10 yrs experience docking a single engine mastercraft in the windy delta in CA, trying to maneuver a massive 45 ft boat has me a bit nervous, and I feel like I really need bow thruster and ideally even stern thrusters. But any experienced boat guy/gal I ask says I just need learn the twin engines.. and I'll be fine. Most the docking will be Sausalito CA in the SF Bay which is windy and a heck of current. So should I only be looking for boats with the thrusters? or do I need to just put on my big girl pants and learn to dock! Also - what does it take to add one if we find a boat that doesn't have any thrusters? Drilling a whole through the hull seem like a big deal, and not ideal to do to an older boat - but maybe people do it all the time. Welcome any input!
