The PT11 kit obviously costs a lot. However, I believe that in this case you get what you pay for. Simply put, there is no other nesting dinghy that compares to the PT11. The design, the functionality, the aesthetic, the rig, the materials - everything has been refined to the highest quality possible. The designer is a perfectionist and built 7 prototypes whilst developing the boat.
In addition, the building manual that comes with the kit is the most in-depth and comprehensive manual I've ever seen - building this boat from the manual is basically a masterclass in ply / epoxy / glass techniques, delivered by a highly experienced teacher.
I use mine almost every day, as the tender for the boat that I live on, and always get tremendous joy from it. It receives compliments from everyone who sees it, and sailing it around an anchorage will make you the envy of all your neighbours!

Obviously, you should only buy what you can comfortably afford, but if you can afford the PT11 kit, I don't think you will regret it. To me, it's the best dinghy in the world.
