I may be late to the party but no less excited about your launch and especially the boat details and the absolutely drop dead beauty of your boat.
7 or 17 no matter how you measure it. Getting up on a plane in a small boat gets the blood flowing and can give you tunnel vision with excitement. To be precise getting up on a plane in a laser gave me the same feeling as going 175 mph on a motorcycle. While unexperienced in the CS, I suspect the thrill is universal across boats, especially if its one you built.
No matter your speed, your boating experiences and pride of ownership will never get old in my opinion.
Good job!
