Agree with Ranga that the reflexes get slower as you get older.
I draw a comparison with a lifetime of motorcycling. In my younger years craved the fastest and most powerful road bike I could afford. Spent a couple of years racing to get it (the need for speed) out of my system. As I got older I evolved from sports bikes to sports tourers, to tourers and now to cruisers (Harley Road King). Why?... because my reflexes are no longer as quick and I have grown out of sliding around corners on knee pads.
Now, I am relatively new to surf skis (ok... I used to paddle skis in the local SLC back in the day which are a bit different to today's offerings
) Having come from an SOT and Sea Kayak background, I tried a number of skis in the past 12 months, some that were supposed to be stable. Stable for who? some 20 something with a body of Adonis? Spent more time in the water than on top.
Steered away from the "beginners" skis as I was damned if I was going to fork out the same dollars for an entry level ski as an Intermediate/Advanced boat. Wrong... big mistake! Took a well-known entry level ski for a paddle (V8) and was impressed with it's stability. Shopped around and tried the Fenn Blue Fin. Fell in love with the thing... stable as and a bit faster than the opposition.
Ok... I am not going to win races on this but I am going to be able to keep up with the longer, skinnier boats in a non-race environment and not be troubled by boat wash, rebound off rocks or cross chop/swell. At 57 and with the wisdom of those years I realised that stability and comfort are what I am looking for so that I can enjoy paddling for as long as I can.
Looking at the offerings coming out from the manufacturers over the last 12 months I believe they too have realised the massive untapped market of more mature paddlers transitioning from kayaks/sea kayaks that want to be able jump into a ski and paddle away without worrying about balance. And that to me is a good thing.
