Grumman Sportboat,Gunter Sailing Rig, Mast Step,& Upper mast mount. this is for the upper (thwart) and lower mast mount . You can get the lower mast mount for either the original square hole for the Gunther mast , or a round hole if using another mast ,
I NEED TO Know What mast size if not the original Gunther,
WHEN YOU ORDER I KNOW THE MAST DIAMETER SO I CAN MACHINE TO FIT . 1 7/8 diameter is the largest we can do with out making a adapter to adapt a larger mast into the hole contact me about this. before order please.
THE Upper thwart IS cut for the GRUMMAN sport boat . It can be cut to fit other canoes, but you will have to cut it to fit.
The lower mount will fit the canoe if the mounting plate is in the boat. if not i have amounting plate that can be bought.
.I am also selling the lee board mount and lee boards, The Rudder, to be able to sail the sport boat. Free Shipping.
