Somebody asked my advice regarding this decision, and I'm am not quite sure what to recommend, I would appreciate your help.

The boat will be on a lake, no racing, just recreational sailing. No need to assemble or disassemble the boat very often, probably never. Kids are grown up and will be sailing with dad just occasionally, so single hading or two adults will be the usual (70 to 130 kg total, something like that). But 4 people on board occasionally would be interesting too.
No major interest in flying hulls or high adrenaline experiences. The lake is big and the winds are light to medium, it's more about lazy sailing, maybe go out far from time to time.

So it seems right to have reduced the options to the two mentioned. The dilemma is that the wave is the more practical choice, it will be much easier to take in and out the water, but: will it be big enough and as fun as the Getaway?
I know it's a vague question, but partial answers may be helpful..
Thanks
