Heeling is a way of life for monohull sailboats. Heeling is, not only natural, but in most cases essential for making good speed under sail. There's a lot physics that go into heeling and determining the proper angle of heel for a given set of conditions, but allow me generalize: Sailboats with narrower beams tend to tolerate larger heel angles than beamer boats. Modern hull designs tend to be faster when sailed flat (heel angles less than about 15 degrees) because they often have less drag with the deep high aspect ratio fin keels and spade rudders. In older designs, heeling increases the waterline length of the hull and helps produce more speed. Again, in general, 15 degrees of heel can be near optimal for many boats. After about 25 degrees of heel on my personal boat, she develops fairly major weather helm. She also has a tendency to want to round-up (turn the bow to windward) from say 20-30 degrees of heel. here
$45-$70), but you're getting a quality clinometer.
$19). The Lev-o-gage Sr has only one scale that reads from 0 to 50 degrees for angle of heal. This gage measures 3.5" wide by 1.5" tall. If you need to measure small side-to-side leveling for loading and want to stick with a Sun Company product, you'll need the Lev-o-gage II, which is similar to the Sr but much smaller and only reads from 0 to 10 degrees.
So how do I know my angle of heel? I have two clinometers installed on my sailboat that tell me the angle with just a quick glance. A clinometer isn't necessarily essential for sailing, but it does help to know at what angles of heel your boat exhibits certain traits (top speed, weather helm, etc.). I've got a Model 2056 clinometer from Rieker Instruments mounted just below my engine instrument panel in the cockpit and a Lev-o-gage Sr. from Sun Company mounted on a bulkhead in my cabin down below.
Both the Rieker and Sun Company clinometers do their jobs simply and accurately. Even if you don't plan to adjust your sailing based on your known angle of heel, it's still fun to put a number with those moments when you're double reefed and the rails are getting wet! more

Okay, so it’s unlikely that you’ll be on one of those gargantuan billion-dollar super yachts that sail the seas of the world’s glitziest resorts each summer (unless you happen to be mega rich). However, you may be lucky enough to have a boat trip coming up this year – whether you’re staying onboard or taking a day trip. In which case, you’ll definitely need to think about what to wear on a boat.
Try sneakers, a boat shoe or sneakers with non-slip soles instead. [links]
A caftan can be a fabulous option either as a bathing suit cover-up or a party dress. here
In 19 years of sailing the Great Lakes, and sharing stories with other sailors, I have heard of a number of knockdowns from unexpected bursts of wind, but only one capsize of a keel boat. That one was a silly design with an AVS near 90 degrees and was staying out in nasty weather on Lake Michigan during one of the Mackinaw races. more
Is this a theoretical or practical question. more
It would help if you defined disaster for us. On our boat, anything over 20 degrees is a disaster according to the admiral, and screeching ensues. The skipper is okay up to 45 degrees, which puts the rail in the water. Beyond that skipper gets a bit nervous, but not yet a disaster. Odds of a knock down in our protected waters is next to nil.
It takes waves to push the boat further. If a boat is struck from the side by a breaking wave taller than its beam, it will be pushed beyond its Angle of Vanishing Stability (AVS), and will be inverted. That qualifies as a disaster! So I think Jackdaw got it right.
