Clearly you are a young fuck who was not around in the heydey of IOR. Kialoas III to V were IOR designs, and damned good ones. Ondines III to V were IOR as well, although they were not great designs and not nearly as successful as the Kialoas. Before you young shits spout off about the lame IOR designs, I should remind you that many, many international race records were held by these "pigs" for decades, beaten only by $25 million canting keel supermaxis (10 to 20' longer than their IOR counterparts) with full professional crews in ideal conditions. Most IOR Maxis were 78 to 82', had amaeteur goons as crew, and were things of beauty. Beasts to sail, especially downwind, but they were not glorified powerboats like the 30m supermaxis of today. Remember the days of 6 to 10 full on maxis at any given international regatta? Remember the days of a dozen or more 50's lining up against each other during the day and their BN's smoking weed and fucking whores all night long? No? I didn't think so. Piss off. Who really gives a shit if a leadmine goes 15 knots or 25? It's all slow anyways. What matters is how you achieve the speed you do, and the IOR boats did it in bling bling bitchin' style. Everybody, and I mean everybody, had fun in those days. Full stop.
