Currently have 4.
Wilderness System Pungo (12'1" Classic) - Still my go-to boat for versitility, menuverability and seaworthyness.
(2) Old Town Loon 138's- Once with Rudder, one without. Great all round yak. Similar in performance as the pungo but is better suited to longer paddles ( due to slightly better hull speed & tracking) and higher weight of gear capacity.
14' Heritage Sea Dart SOT( with Rudder)- My only SOT left ( after 3 others)- fast, nicely designed/featured SOT that looks like a yak vs a bar of soap A bit tight for fishing but great for paddles where I want to get in/out of the yak routinly.

My ONLY advice is to TRY BEFORE YOU BUY REGARDLESS OF WHAT YOU READ FOR REVIEWS.
One mans' perfect yak is another disapointment! Been there-done that-it's expensive
