If your family might want to go paddling with local club, or more experienced kayaker, I bet they will have hard time keeping up with them.
Why not Tern14?
Sushiy, Love your posts and always enjoy you point of view. So hope you wont take offense if I disagree on this one.
I too have been looking at the PS-13 and and the AT-14 for a someday build. Unless the paddling club is going at near full sprint to reach possible hull speeds the PS-13 and AT-14 will actually be less work to paddle at "Standard Cruising Speed" (SCS) as defined by Pygmy in a recently received mini catalog announcing their 3 new kayaks.
That publication says "lower is faster". Below are the SCS numbers they published:
Pinguino Sport ---- 16.85
Artice Tern 14 ----- 17.01
Standard Osprey --19.18
Coho ---------------- 19.33
I know that the Coho and Osprey are certainly faster designs....when enough effort is applied. However as Pygmy describes " Kayak cruising speed is proportional to the boats wetted surface, which is the area of frictional drag of the water on the hull, here expressed in sq ft."
Pygmy goes on to say; "A boats theoretical hull speed (THS) is a function of square root of its loaded waterline length (LWL). At approximately 80% to 90% of its hull speed a kayak will start to produce a bow wake longer than is LWL and the effort required to continue acceleration rapidly increases. The standard cruising speed of most paddlers is below 80% of their THS, and for differing boats speed relative to effort is primarily determined by frictional drag and wetter surface of the hull and not the boats length. In some cases a shorter boat like our Tern 14 is easier to paddle at standard cruising speeds."
I can not verify any of this from my real world kayaking experience.
But from my 30+ years of racing sailboats at National caliber competitions, I can confirm that at less that hull speed conditions the shorter, less wetted surface, boat can often out preform the longer hull given equal power from the sails.
To add to the original question I'd strongly suggest a test paddle at Pygmy. " All may be reviled when real world experienced"
just my $.02 worth, barely. ds
