I agree with all the above -- AND disagree with all the above. Everybody has thier viewpoint, so here's mine:
Tied up in the marina you'll love the dockage costs of the 40 footer.
Out there on the wide and wild blue seas you'll love the 50 footer. (I want an aircraft carrier that folds up into
dinghy sized when in port.)
I've a 48 foot cutter-rigged
sloop and I'm 61 years old. So let's talk about aging...
For the
sails and thier weight and other required muscle
power:
1) Get good winches and lubricate/maintain them.
2)
Sails: I've added a double block at the mainsailhead and an additional block at the mast-top. Yeah, its a lot more line, but instead of a 1-to-1 ratio I've got 4-to-1
power when hoisting by hand. Plus the power of the
winch.
Electric? We don't need no stinkin' lectric.
I use the same principle with our spin-drifter.
3)
Anchor: see sails and use of multiple blocks for leverage - if, or when, the windless acts up. That spinaker
halyard is useful. {Or even the headsail
halyard.}
4) We would never hire a crew to 'help" sail our
boat. If my wife and I can't handle it then I'll run the
boat onto a beach at high tide in Malasia, throw rocks under and around the
hull, and retire. {Again.}
5) Reefing: If you THINK about reefing, it's time to reef. Don't be a hero. We always reef down at dusk - 'cause you can't see the squalls coming in the dark. Reef early and it doesn't take that much muscle. If you're in a hurry then take the plane!
Other thoughts:
1) Clotheswasher: we've a small {2 Kg} cold-water unit. Hot
water from the stovetop kettle if needed. Store below when not in use. Runs on 12V. Dryer: fully green!
Wind and sun and a clothesline.
2) Dishwasher?!?!?
3)
Storage: A bigger boat just has more space.
Some folks wear the same T-shirt for a week; some folks like to dress up when they hit port. Everbody needs an assortment of
weather gear">foul
weather gear. Unless you buy all new kit in each port you're going to need space for clothes. Add in spare
parts, extra sails,
motor oil, jerry cans, etc. etc.
We like to have six-months worth of canned foods aboard. We stock enough
drinking water for two months in case of no rain and a broken
water maker. {Water maker works? Yay!} Four tanks/bottles of propane/butane gives us four months
cooking.
We've
solar panels {4x 85 watt} and a
wind turbine.
Batteries of 800 Amp/hour rating. {4X Rolls/Surrette T-12-250} No need to start
motor for
battery charge. Bigger boat has space for that kind of stuff.
You might LEAVE port for a three-week
cruise, but tsunamis and storms happen and your
destination port and its support infrastructure might be out of action when you get there.
Did I mention that a bigger boat has more space for essentials, like wine and
beer?
{Okay.... soft drinks and lemonade if you'd druther.}
Running costs: Yes, the bigger the boat, the higher the
maintenance costs. Balance that out against the value of your wife when the storms kick in, the winds hit 55 knots, and the waves are 12 or 13 metres. But then again... Maybe you will never experience such conditions.
Bottom line for us: The bigger boat if you can handle her.
