I'm planning on replacing the janky old ProFurl jib furler at the next haulout. I see that alot of people really like their Harken furlers, but I have two options to choose from: the standard MkIV or the MkIV Ocean. I have watched the Harken videos explaining the models and I understand the differences. It appears the Ocean model would suit my needs and is considerably less expensive than its counterpart. However; I am wondering if anyone has real-world experience with the Ocean model vs the standard MkIV. I doubt Harken makes any sub-par products but I want to avoid any disappointment if possible.
