The 505 is one of those boats that just feels alive. A two-person, high-performance centerboard dinghy. Fast. Like, really fast. John Westell designed it back in 1953 in the UK, originally calling it the "Coronet" before that numeric name stuck. World Sailing recognizes it as an International Class. Honestly, it's probably one of the most demanding two-person dinghies you'll ever step foot in. You need coordination, athleticism, and a bit of a crazy streak. Experienced racers love it for that raw, responsive feel. It's not forgiving, but it rewards skill. Speed comes down to two things here: that long, narrow hull that just wants to plane, and a sail plan that packs a serious punch. The hull lifts up onto a plane without much fuss, letting you surf down waves and hit 20 knots plus. Here's what helps: The 505 fits somewhere between the Olympic 470 and the classic Flying Dutchman. Think of it as the hot-rod cousin. Quick comparison below: Honestly, the 505 is more demanding than the 470. More physical, more technical. It's faster, sure, but less forgiving than the Flying Dutchman, which has that heavier, more stable hull. You mess up on a 505, you feel it immediately. No way. Not even close. This is not a learner boat. It demands experience, strength, and advanced technique. Beginners should stick with something simpler, more stable. A Laser, Sunfish, or a 420. The 505 is too sensitive to weight placement, too powerful, and the control lines are a nightmare for someone learning the ropes. Best for sailors who've already got trapezing, spinnaker handling, and planing down pat. The rigging is where it gets interesting. So much adjustability, letting you tweak the sail shape for whatever wind you're dealing with. Key bits include: Depends on what you're after. Age, condition, gear. Here's a rough idea: "The 505 is the ultimate expression of dinghy sailing. It's not a boat you just sail; it's a boat you fight. The feedback through the tiller, the acceleration when you plane, the precision needed to hold the groove—it's addictive. If you want to feel what a dinghy is truly capable of, the 505 is your answer." Before you pull the trigger, think about these: If you said "yes" to most of those, you're in for a wild ride. The 505 will give you speed and excitement like nothing else. No strict limit, but ideal combined weight is around 140-160 kg (308-353 lbs). Heavier crews might struggle in light air, lighter ones in strong winds. It's a balancing act. Technically, yeah, but it's a nightmare. Not recommended. Designed for two. Single-handing takes exceptional strength and skill, especially with that spinnaker. Absolutely. Still built by custom builders like Ovington Boats (UK), Boatspeed (USA), and Lanaverre (France). New boats are made to order. The 505 is longer, faster, and way more powerful. The 470 is an Olympic class, simpler, more forgiving. Great for advanced club racing. The 505 is a pure performance machine for experts. No contest.What is a 505 sailboat
