So, I suppose "work" is relative.
The actual sailing is a little more work than driving a power boat, so my powerboat friends say. You have to look up the mast occasionally, make course adjustments and then there's tacks and making your guests move to windward if needed.
But to me that's less work than to put up with "RAAAAAAAAAAWWWWWRRRR" of the motor the entire time you're out. Gives me a headache. You can have a conversation with other sailors until you're out of earshot while sailing. Hard to do on a powerboat. And being out 1 hour or 6 hours, it costs the same in a sailboat. Not so in a power boat.
But sometimes the weather isn't cooperating though so that one day off you have this week might not be a good day to go sailing. And there's a bigger learning curve than with a power boat.
The rigging lasts longer than motors. You check it to make sure lines aren't chafed, nothing's corroding, etc but that doesn't take too long. Friends I have with power boats are always having to mess with the motors. Occasional use is really hard on motors.
One of my boats hasn't required any work other than a wash and wax for three seasons. Her sail is ~35 years old and could use replacing. She'll still get up on a plane though.
Miss Muffet was behind on maintenance so I'm upside down in maintenance vs sailing hours, but I don't think she's a demanding boat once all of that is done. We're still getting to know each other. In less than an hour I tensioned the shrouds, figured out some unfamiliar rigging, and was casting off.
Penelope...holy s***. She's been a regular diva.
She requires bribes in teak oil, elbow grease and money before I can even think about getting her out. But she was stored under a tree for six years before I got her, so I guess that's why she's a bit grumpy. Otherwise, some teak oil and spar urethane once a season is all she's supposed to need for routine maintenance. I need to clean the carb on the outboard...it's a bit pissy at low rpms.
