The upgrades will come thick and fast!
I started my love of water as a surfer as well. I spent many days staring at flat seas, wishing for Atlantic swells, but they never came so I swapped to boating. Now its too rough to go our most of the time!
After a few years of bigger boats, mooring fees and antifoul, I now have a tow-and-go anywhere 5.35m RIB, so cheaper boating and not limited to open water when it is blowing.
Good luck with the Honwave, it is a capable SIB and will go nicely with a 15hp motor.
