Very short yaks, tend to not track well and snake side to side as you paddle, but this depends on design. Long yaks are good for offshore in swell ect, but don't turn well, but a rudder on such a craft will alleviate this a bit. Narrow and it will be fast and easy to paddle, but tippy side to side. Fat will be stable, carry more weight, harder to paddle and slow.
I would keep it under 4m, under 25kg, with a load capacity of at least 130kg. Around the middle some would say.
