Doug,

Sorry my answer wasn't complete.
My Harken Furler is a Mark III, model 0 and it is replacing the same.

I love it. When I was talking to Herb Hild about a head sail for my old
furler, he said " Anything that will keep me, my family, and my friends
off the Pointy End of the boat, while under way is a good thing." That
is my Motto also.
