Maneuverability will still come down to the design of the boat. Long keel
vs short keel
. Deep v hull
vs flat planing hull
. Left or Right hand Prop Walk. Freeboard windage. There are so many variables. So its really impossible to compare the two based on size alone.
There are few things you can do manually on a bigger. On a small boat you can manually sheet on a sail or raise a halyard
. But on a 41 footer, just about every line will need winching.
Even gybing will be different. On a small boat you can just grab a bundle of main sheet half way up the tackle to assist the gybe. On a bigger boat, you will have to sheet it in to the center then release- else you risk breaking a wrist.
But as long as you prepare for heavier loads, sailing wont really be all that different. Make sure your reefing lines are prepped and that you test the system. There's no point learning
that the reefing system is flawed once the poo hits the fan.
Your comparison of wind strength vs length is flawed. 15 -20 knots is fun sailing for all classes
. Where as 30-40 knots is hard work in all classes
But get out there and enjoy it. Sounds like a fun trip.
