I'll bite.
@BlackPirate: I'm going to digress and give you a chess quote. I've played the game ever since I can remember, love it, there's an old saying "Chess is an Ocean where a Gnat may Drink and and Elephant may Swim." The Daysailer is much the same - good for beginners, good for "experts." Uffa Fox, the designer, deliberately designed it that way and he certainly delivered. To the tune of 13,000 DS's built and many imitators, which is HUGE for a sailing boat production run. George O'day added one nice feature to make it a "family boat" - the cuddy! What a great place to put a cooler or some sleeping kids. Also keeps the spray off of you. You can sail it alone, you can sail it with 6 adults, and its perfect for family.
So, why is it good for beginners? Because it's easy to get moving, relatively stable/well-behaved, and uncomplicated. It has just enough responsiveness that you quickly learn to "feel the boat" - believe me an unresponsive boat is both a drag to sail and dangerous. On the other hand, it's not "twitchy." Yes, you can capsize it, you can capsize any boat, but it's not a boat where you're constantly at the "razor's edge." To put it in military terms, the OODA cycle - "observe–orient–decide–act," is quite manageable, maybe 5-10 seconds during EXTREME sailing, and you won't be doing that at the beginning. Regular sailing, you have plenty of time (measured in minutes) to have a think, make mistakes, adjust. Now, admittedly, this all depends on what the regular winds are like in your area. The DS is "happiest" around 10-12 knots of wind, although still lots of fun and easy to sail with more or less wind. If your area regularly has 20 knot+ winds (I'm looking at you, SF Bay!) then you probably want to start out with a keelboat. More stability, but also a LOT more expense. By the way, the DS is primarily a lakes and inland waters boat - you can but I wouldn't sail it in the ocean (or the SF Bay). Yes, there are lakes with LOTS of wind (Flathead, MT), don't choose those for your beginning sailing.
Sailing newbies are usually worried about 2 things "What if I get caught in strong winds?" and "How much will I heel before I capsize?" The DS is relatively good at handling higher winds - ease the sheets, drop your sails, run with the wind. Nowadays, it's so easy to "choose your weather" - windfinder.com, for instance. As a beginner, definitely start on lighter wind days (4-8 knots) and work your way up. As for capsize, the one big difference between this and a keelboat is that it does NOT have a weighted keel, so the only thing holding it upright is you... you need to move your weight outboard as the wind kicks up. I usually sit on the side decks and lean out in stronger winds, you'll quickly get used to it. I've had the lee rail (lower side when the boat is heeled over) under water, even taken green water into the cockpit (i.e. water washing over the deck and pouring in). That's a bit over 45 degrees of heel, and you can look down and see the centerboard slicing thru the water. No problem, boat was stable as can be - her width helps keep you from capsizing and she has a big "belly" in the water when heeled over, due to the way the hull curves. Now, despite the stability when heeled, you definitely want to sail this boat flat - heeled hard over is SLOW. Word to the wise, do try and bring a friend along when first learning to sail - even if they are not actively sailing, they can help you keep the boat weighted down - "active ballast" - all they have to do is sit where you tell them to.
Which brings us to why the DS is so lovely to grow and learn with. There's just do much to discover, a lot of subtlety. Think of it like learning to ride a bike - there's a basic skill of staying upright and pushing the pedals.... but then there is all the fun of learning how to really LEAN into curves, or glide down a hill and use your momentum to burst up the next hill, etc. As opposed to most beginner boats - Sunfish, dinghys, etc - there is no "upper limit" of what you can do. Ok, I'm generalizing horribly - there are some amazing dinghy designs - but pound for pound/length for length/dollar for dollar, the DS really hits a sweet spot of everything you want to do in a sailboat without (most of) the aggravation and expense of bigger or more complex boats.
So yes, I think a DS is both "for you" and safe for beginners.
