I completely agree with the comments above that bigger and heavier is easier.
Fintry is 79' and weights around 350,000 pounds with full fuel and water. The wind doesn't push her around much. She is the easiest boat to handle in tight quarters of any I have driven -- single or twin. Of course, "tight quarters" is a larger space than it is for a 35' boat.
She has a bow thruster, but, more important, she has a 5' propeller and rudder to match. Without using the thruster, I can nose her into the dock at about a 30 degree angle, so that she touches about 15' aft of the bow. The deckhand can get out with the spring through the gate there. Or, she can use a boat hook to put a loop over a cleat a little aft of midships. Once you have the spring on, put the rudder hard over opposite to the dock and go forward very slowly.
That works fine if the dock can take it. Many can't -- you'll move the dock more than you move the boat.
The alternative on Fintry is for the deckhand to put the spring on, toss a stern line onto the dock and then go ashore and put the stern line on a cleat. Once that's done, the deck hand can come back aboard and winch the stern in. Fintry has an obsolete three speed sailing winch on the stern which makes it easy to pull the stern in.
Note that most big boat captains handle their lines backward to common marina practice. They put a loop ashore and adjust the lines on board. This is particularly good when you give a line to a "helper" on the dock -- you can tell them to simply drop it on "that cleat" and they don't need to apply any judgement. If they try to pull on the line, you can tell them again -- "just drop it on the cleat". Many dock "helpers" -- including marina employees -- will try to pull a heavy boat in. As noted above, that's marginal for a 100,000 pound boat and impossible for Fintry.
One advantage Fintry has that your boat may not -- there's an 8" high rubber rub rail all around, so the only place she is vulnerable to damage is the swim platform.
Also,
SeaStarDF50, just above, mentions headsets. Our Eartec headsets are one of the best things we have. No yelling, the deckhand can constantly talk me in or out so that while Fintry has both a mirror and video camera, I don't pay attention to either. Also I can tell her which cleat I want a line on and she can tell the "helper" on the dock from a few feet away -- no yelling, no loud hailer.
