It is a Luger Leeward 16. Do a search here on the forum and you'll find a member
who is doing a total renovation
If this one is in good shape and used stainless steel
for its fittings and nuts and bolts it should be good. There is a plate on each side of the centerboard
trunk that was made of aluminum
and might be corroded beyond repair. Check that out. Also check the hull
stiffners in the cockpit
sole. They should be firm and not soft. If any of the wood is rotten on the inside of the boat you may not want to take on the reconstruction.
Good luck. If the original owner put it together well and all the rigging
is good and has been maintained then it should be a good sailer.
