Questions 3 & 4 are not relevant to this as I'm trying to find the right boat and then I'll see how to pay for it.
EU RCD is too a wide classification. My little boat is cat. C same as a Warrior 17', but the difference is huge.
I'm after something more precise. For instance with the sea there is the beaufort scale. Looking at that I can very accurately compare the sea state in two different days.
The same thing I'm looking to find out about hull shapes. Something that is factual, numbers that you can compare.
This takes me to the tworotorturbo's reply. It's a way to test different hulls and find out the best. However that's very difficult to achieve (unless you've got lots of money you can't line up 10 RIBs and test them in exactly same sea conditions and even if you do that, you're feeling are not always the same) and not too factual. You mentioned about SR4 that has deeper V than other boats. That's not quantifiable. How deeper? 10% more, 20% more etc.
I'm still searching.
Thanks all again.
There isn't a magic formula that will produce the perfect boat. For a start, the sea is infinitely variable in it's conditions, chuck the wind & tides into the equation & you have virtual chaos. There isn't a "best" hull, if there was, we'd all have one. There will be a hull that will satisfy some of your requirements, some of the time. It isn't an exact science, too many variables. The best comparison you'll get is the previously mentioned RCD directive, after that it becomes subjective.
