Which boat do I buy

Cool. You'll have fun in a Laser in waves.

It depends on budget, but assuming its second hand, laser is the obvious choice. Most clubs allow the use of replica sails in normal racing, so Rooster sails can be used and their radial is nicely cut and much cheaper than the Laser red button sail. If you get into it, in a couple of ]years you can move up to a 300 or by that point there should be s/hand RS aero's on the market which work very well inland and on the sea - also dead easy to cartop. 

I'm using Apollo Duck to search and email possible sellers, but after email several people a message has come up saying ''Service Unavailable" and it has done this multiple times, how do I go about contacting people now?

I love my Solo but then I am in my fifties while you are 16 years old. All the young people I know who have sailed a Solo are really surprised by how much fun they are. But, as a realist, I appreciate that there is no real street cred to be had from sailing a Solo!

At your weight, you could just about manage a Byte C2, but you must promise to never, ever, ever eat again......
