Re: How a yacht works: sailboat physics and design
#32I've been getting into sailing, solely for the purpose of cruising and sailing for fun with no interest in racing. As I've started talking to sailors, I've realized that you need to gauge whether you're speaking with a racer or a cruiser. Racers will claim these are not mutually exclusive categories, because of course racers can also cruise. But racers who cruise will ultimately talk to you like racers. Racers are, a…
But what is not obvious to cruisers is that racing teaches you how to handle your boat in many different and difficult conditions, with confidence. When you race you have to go from a specific place to another specific place and you don’t get to pick the weather. You’re often pushing your boat and are in high stress situations.
Often, cruisers will go out, when it’s nice, and turn on the motor when they can’t make their boat go the way they want it to go.
So, what happens when you’re out sailing and an unexpected storm rolls in? Because if you sail enough, especially offshore, it 100% without a doubt will happen. I’d honestly be pretty comfortable handling the boat through all but the worst weather, boat breaking weather. And even that, I would be confident in my safety gear and ability to contact support for a rescue. Because all of that is drilled into you as a seasoned racer. And I’ve been through some bad weather on the race course. I’ve had to make my boat go upwind in horrible sea state for hours on end while my crew is throwing up from sea sickness.
There are multiple occasions on which I’ve turned down sailing with cruisers because I just don’t trust that they have the skills or equipment to keep me safe should things go sideways.

My sailing buddies and I are always asking each other, “why is sailing dying”? Sailing is a very self selecting sport. People generally love it or leave it very quickly. We are in the “love it” camp, and we are always super excited to take people that are curious about sailing out sailing. I would strongly suggest not taking classes. Just get on a boat. It is hilarious how easy it is to find a sailor that will take y…
If you’re in Charleston, SC, check out Charleston Ocean Racing Association (CORA).
Or if you’re somewhere else and interested, message me, and I’ll do my best to find a place and make an introduction. The sailing community is a small world.
Maybe I’ll see you out there!

School is fine too but you’ll realize that you’re mainly just paying for access to the dinghy anyways. The instructor isn’t going to teach you anything that’s not in a book or that you won’t learn crewing someone else’s boat.
Hope you have fun though with whatever you decide

I never ended up on a real-sized sailboat. But, I had fun on a little Sunfish as a teenager. They are nice because you can reasonably learn to sail them over the course of a couple days, and if you flip the boat over you can probably right it without too much drama. Just don’t bonk your head.
I did some river/lake sailing as a kid on the East Coast but now the urge is calling to me! I remember the "righting the boat" test being the scariest/most fun part of the experience -- super glad I went through that and feel confident on a small boat.
Now...I used to remember all the knots we learned but that memory is mostly gone
Re: How a yacht works: sailboat physics and design
#36This site is an absolute treasure trove of technical material on sail and hull design, with a focus on model yachts but most of the physics scales up. It covers aerofoil theory (momentum, circulation, lifting line), sail twist, downwash, planform effects, Reynolds number, hull resistance, appendage design, VMG, and more. Lots of spreadsheets and practical calculators too—bulb shape optimization, wetted surface area,…

I learned to race first and am now learning to cruise. And I’m glad I learned in that order. Cruising has a very specific set of skills that you’ll never learn racing. That stuff will be obvious and if you want to cruise, you’ll learn those skills. But what is not obvious to cruisers is that racing teaches you how to handle your boat in many different and difficult conditions, with confidence. When you race you have…

#39Earlier quoted context omitted.
Racing isn’t what used to be, but sailing very much is. There are roughly two kinds of sailors: those who care about speed, and those who care about comfort. They have almost antipodal design requirements, but both kinds are very much sailors.
Do you know of any good technical / physical comparison of the two, or just of the comfort designs?
They bear nothing in common with a typical monohull cruiser, or even racer-cruiser like a J-109[2]. Let alone compared to a comfortable cruiser like a Hallberg-Rassy[3]. These are all displacement hulls, whose speed is fundamentally limited to waterline-length.
There are monohull sailboats that can plane (most dinghys under 20' for example[4]), and there are large catamarans that can go much faster for their size than monohulls[5], but there are many tradeoffs in cost, dockage availability, and (somewhat subjectively) weather comfort.
