Yeah, I miss the days when a higher proportion of this Internet was content like this.

Nice to see an enthusiast/engineering site that is putting cutting egde design ideas into the public domain. Grew up with boat builders on the south shore of Nova Scotia, and knew and learned from some of the last people to build and crew working schooners, that were also raced, I a boy, and they proud old men. Also know current builders and restorers of blue water boats. A few years ago I stumbled onto footage of a big hydrofoil cat that was the first boat to break the 50 knot barrier, you could tell that any celebrating was waiting and would largely be to celebrate still bieng alive, big seas, 50+kn, and quite clearly nothing but flinders left if anything broke and they plowed into a wave.,..,........they were standing on deck

These are good animations for tall ships:

Warship: https://www.youtube.com/watch?v=4Nr1AgIfajI

Explorer: https://www.youtube.com/watch?v=3pYqXrFx6S8

They don't cover the actual physics and processes of sailing a tall ship, but they do explain all the parts and pieces and how they connect.

Seems like a good contender for a https://ciechanow.ski/ interactive article.

I'd love to have a simulator for a sailboat, preferably running in a browser.

There is a modern-ish simulator here: https://thapen.itch.io/painted-ocean

The tutorial level on how to get the ship pointed in the right direction and moving out of the harbour will give you the basics.

Ugh. The slot theory lives on. The physics textbook still used at Berkeley, Giancoli, used the slot effect as an example despite … Gentry being a Berkeley grad. I sent a letter. I never got a response. However, the latest edition deleted the slot example and instead uses the Bernoulli principle yet stops short of Runge Kutta circulation.

Isn't that the case with every hobby?

There's also a specific argument in selling the racing is a better way to develop sailing skills because cruising ideally may not challenge you.

I finished my first race Wednesday after a few years sailing casually. And, although it’s true that whenever there is more than one sailboat going the same direction it’s a race, being in a fleet on a defined course is much faster paced and precise. My analogy to driving is that cruising is being able to drive on empty roads, and racing is driving in traffic — it becomes about understanding the flow and rules spoken and unspoken.

Spot on. As a racer, I can say this is mostly true. Although for me and many of the other racers I know, it's less about going deep into the optimization, sail choices, etc, and more about just being competitive. Racers don't always make good cruisers because they're always trying to go faster and push harder, whereas most cruisers want to slow down and enjoy the journey.

Exactly right. I’ve known from when I started sailing 35 years ago that I was a racer.

Sailboat racing is amazing; it’s this incredibly complex exercise involving physical boat handling skills, teamwork, leadership, communication (in a jargon that itself takes a year to internalize), as well as physics, geometry, meteorology, and minute observation of effects (that dark patch on the water or the flutter of a telltale). All of this feeds into strategic decisions on where to position your boat and tactical decisions of how to do so.

It looks crazy boring from the outside but if you get into it, it’s an activity that is intensely mental as well as physical and requires a very broad set of skills.

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 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.

If there's more than one sailboat, it's a race :)

I've been seeing some modern junk rig refits on the great lakes the last few years, which really gives me hope about dedicated "get there when we get there" sailors. Those things are basically optimized for chilling the fuck out. Easy to sail (entire tacking maneuver is basically just throw the rudder over and duck), easy to reef, don't heel as hard, straightforward to mend the sail or running rigging on the fly.

Only downside is their close haul is like 12º off the wind vs a bermuda rig and no one knows how to make them. The east coast (esp chesapeake) has some traditional gaff rig setups that have similar tradeoffs, like catboats. I would love to see more small production boats target this end of the "speed/comfort/cost" triangle. Currently it's like if the only bicycles available were race-ready track bikes. But sailing is already a small niche and new boats even smaller I think.

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.

There is an after-school boat building thing that just started up in crane cove Park too

There are a ton of opportunities at South Beach Marina

There are many sailing schools around SF, but one that stands out is https://www.cal-sailing.org/ - as it's by far the least expensive and low-commitment option to get on the water, and they have dinghies in which you'll learn very fast (but also get wet). Instructors are regular volunteer club members and mileage may vary, so make sure to go out with a few different ones.

Another good way to get started is to find crewing opportunities for casual racing on https://www.latitude38.com/crew-list-home/. Many skippers will take no-experience folks out for fun. (It may take a couple of attempts to find a skipper/crew you enjoy hanging out with)

Spinnaker might be great - I don't know them - but if you're in the market for sailing lessons in SF Bay I can highly, highly recommend Club Nautique out of Alameda[1].

The quality of instruction is very high, with a focus on safety and building a strong foundation of knowledge. Especially if you ever might want to charter in remote locations or sail across oceans, it's really an excellent foundation.

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 you out. And if you enjoy that experience, people are always looking for crew to help them sail their boat. So I’d suggest your next step would then be that. You’ll learn so much faster going out for Wednesday night races at your local club. You’ll learn both how to sail and whether you even enjoy it. A lot of places even have a “crew seat” where you literally show up, not knowing anyone, and people see you sitting there and ask your qualifications and if they have room on their boat and are comfortable with the match, take you, a complete newbie and stranger, out sailing.

Classes make it easy feel like you’ve learned “levels” of sailing or to feel like you could rent a boat in the Caribbean. But, they hide a lot of what sailing is really about. Maintenance, rigging, de-rigging, showing up for no wind, learning the rules of sailing, etc, etc. They also miss out on one of the most amazing aspects of sailing: community. Learning from other sailors is key. You’ll borrow parts from (and lend to) other sailors. You’ll help organize races for them and they for you.

Sailing is a beautiful, beautiful lifelong endeavor that I wish everyone could be exposed to and pursue if they’d like to. Look up your local yacht club or Hobie / beach cat fleet or other sailing club and just ask if you can get a ride. Show up early, listen and do what you’re asked, be polite, stay until the boat is totally put away, and repeat. Try different boats with different clubs and people eventually.

Eventually, maybe take a class (RYA not ASA) to formalize your knowledge or fill in the gaps. You’ll clearly know what they are at that point. Eventually maybe buy your own boat, or do as many people do, just keep crewing. Truly good crew are really rare and boat owners will love and appreciate you.

I think you’ll love it.

My buddy has a 36' Pearson in the Berkeley marina, sometimes we bring folks out with us.

You can also join the Berkeley Yacht Club (BYC) without a boat, it's not too expensive. There's a bar and social events, good way to meet sailors with boats in the marina and go sailing on a variety of them. They hold races in the bay pretty often, and are sometimes desperate for able bodied ballast.

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.

If you have the space the best way to learn how to sail is just buy a cheap dinghy and take it out as much as you can. While you’re looking for a dinghy just read a book on theory. Something like a laser is the ideal platform to learn on and you can go out in the bay and check out Angel island and other fun stuff like that. If you want to get more experience with things besides pure sailing then just crew someone’s boat for free. When you’re done, sell your dinghy, get your money back, and buy yourself a sloop. This is pretty much how I learned how to sail.

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

Cal Sailing Club is a great way to start. You'll learn more quickly on dinghies than keelboats and the skills will benefit your entire sailing career as you move on to bigger boats.

Also check out the Friday night races at Berkeley Yacht Club. Skippers always need crew so it's pretty easy to get a ride. Just hang out at the gate between 5 and 6pm with your gear and say hi!

https://www.berkeleyyc.org/racing

Cal Sailing is a good way to get on the water and learn the basics. You can learn dinghies, keel boats and windsurfing. After you're comfortable with basic keel boat crewing, you can probably get a ride on a boat in the Friday night beer races at the BYC. I started at Cal Sailing and eventually raced at the Rolex Big Boat Series at the St. Francis.

Larry Ellison started at Cal Sailing and Lowell North was dinghy chair in its previous incarnation as a UC Berkeley club.

Goofy fun place.

Other people have echoed the same advice, I’ll add to it.

Take enough of a learn to sail class that you understand the basic theory —- I took one at my local yacht club.

Then, find a racing fleet! Racing boats need crew weight to help the boat sail towards the wind (so you can be useful while you are still learning), and not all the jobs require as much sailing knowledge as others (my first job was to pull the free end of the line while someone was winching in the sail).

Skippers value consistency —- the boat can’t race without a crew, so literally just reliably showing up is a valuable thing.

I have just started sailing in the UK. I can't recommend it enough. It's great time away from the computer in nature but still doing really complex technical tasks. The best thing imho is to find and join a local club. There are many that aren't snooty (having Commodores etc) and it's pretty affordable. Members will always be looking for crew. I really wish I had done it sooner.

Join a club. There's also facebook groups looking for crews. But i guess if you don't have experience, you kind of have to provide an incentive like contributing higher towards the common costs.

Seattle area recommendations:

- Low-cost: If you volunteer at the Center for Wooden Boats (helping around the docks, helping with rentals, etc.), you get 1hr of boat rental for 3hr of volunteer, and you get free sailing lessons after 45hr of volunteering. Really friendly bunch! Great way to learn in smaller boats for free. Plus you pick up some skills while you're volunteering. Or you can buy lessons and become a member -- boat rental is relatively cheap here. There's also Sail Sand Point, which gets you out on lake washington on little lasers.

- If you want to get out on the sound, Seattle Sailing Club (SSC) has great instructors and friendly people. They offer most ASA courses (e.g. ASA101 over a weekend is a great introduction to sailing). This approach is more expensive, but good if your long-term goal is more "serious" sailing on the sound in bigger boats. You'll have more classroom time, a textbook, quiz, etc., and probably pick up more knowledge overall.

You can also look into Puget Sound Sailing Institute, which is a bit cheaper than SSC, but not as community oriented. More locations outside of Seattle though.

Start with dinghy sailing, there are few places in the area you can take a class, rent boats, and race. You'll meet people, and become a better pick for a crew member.

I own (half of) a racing boat on the Great Lakes.

Buying a boat brings with it dreams of freedom, winning races, beautiful summer days.

The reality is that you need crew! Serious racers will refer to their boat as their “program”, and are always looking for careful, reliable crew.

I’d say look for a “learn to sail” program at whatever yacht club is nearest you, then see if they have a club racing scene. Most clubs have both.
