Jack Mitenbuler asked me to post these two kayaks for sale.   They belong to a friend of his who lives in Michigan.    He estimates that both boats are about 20 years old.

First Boat:   $500, Nigel Dennis Kayak (NDK) Greenlander, Ocean Cockpit, 17.9 feet long, 21 inches wide., fiberglass.   (The Greenlander has the acutely upswept bow.)   Does not have a skeg.

Second Boat:  $300  Bay  de Noc Kayak.  Jack said that this was about the same length as the other kayak (17.9 feet) and is a fiberglass boat.    From Jack on the Bay de Noc: " If I wanted a project I’d go for the Bay.  Nice lines, hard chines, keyhole cockpit,  recessed fittings.  It (the Bay) does need new hatch covers.  One never knows till they paddle a boat but it appeals to me.  I’d go to the the trouble of adding a skeg and of course clean the glass and restore the gel coat.  The Bay is the $300 boat. "  

If you are interested, these are tremendous prices on these boats.  Contact Jack with any questions you may have at:  jackmiten@gmail.com'
