In Dubai, we have 3 Spitfire’s & 3 Blades racing. I race a Blade, for me, the key reason was the boat weight & no min. crew weight. Two up with the wife, we weigh in at <110kg (so playing by the rules, we’re even too light for a H16 unless we go 3up). Two-up, we’ve raced in 20kn+ with some wins and without swimming. Usually from around 15kn and up we’ll sail two-up without the jib, which is an excellent option (though not sure what SCHRS we should be on??). Sailing 1-up, I’m about done at 15kn, just too lightweight for the power. Also sailing here are 3 Shadow’s. One of the other Blade sailors previously owned a Shadow, but in our typical winds of 10kn, he was just too heavy (~100kg) for it. He’s doing well 1-up on the Blade. One of the spitfires does race one-up, leaves the jib behind and is competitive. Spitfire or F16? Both excellent classes and best you try them both. If you’re in Dubai come up to the club (now “Mina Seyahi Yacht Club” I think, previously JASC) on a Friday and have a chat/sail.
