Just done my Intermediate PB with Powerboat Training UK. Excellent course, made easier by good instruction. Recommend them to anyone in the Poole area, even if someone drove from Cyprus on my course to do it!
Im no where near an expert but any good course gives you more experience, and it definitely gave me that.
Now, just to find the money for my own 7.8 RIBCRAFT!
Cheers to Dan and Simon.
