Hi Darren and welcome to Ribnet.
Short answer to your question is:- yes, you can wakeboard if you have a strong stomach because the smell of diesel is not to everyone’s liking
, top speed is 28 knots, I cruise at 26 ish and fuel consumption is about 1 ltr /NM at WOT
As to whether it would be cheaper for you to own a P22 is a big question and depends on a lot of differing factors. It is cheaper for me because I use the boat a lot, I do my own servicing and repairs, I have a boat that was in reasonable condition when I bought it from the RN so I expect a reasonable length of time before I need to do any major overhaul and sadly (because I have very developed anorak tendencies
) I don’t mind working on it if I have too
When this boat has let me down it is usually for a very good reason whereas my previous boat that had an outboard would let me down for the stupidest reasons you can imaging
It had a lot of little black boxes full of smoke and if something went wrong the smoke came out and they wouldn’t work
drove me mad
