As it becomes necessary to replace blocks and other deck gear, we are replacing them with Harken equipment whenever possible. We have never had a failure to date, and they stand behind their products: When the bearings on our 16-year-old Harken jib roller furler system needed replacing, Harken found the parts and did it for a reasonable price, making it as good as new. Most companies would have told us to buy a new one. They have done a couple of small customization jobs for us cheerfully and efficiently. A great company!
