HARKEN
Cam Bases

Use cam swivel bases when leads must rotate to face the trimmer.

Ball bearing swivel bases feature dual rows of Delrin® ball bearings that swivel freely even under high loads. Bases include stand-up springs and a U-Adaptor to accept a variety of appropriate blocks.

The 144 is the standard configuration with a tall arm. It is ideal for mounting in the cockpit or for use on larger keelboats and small offshore boats that use 76 mm (3.00") plastic blocks. The low-profile 205 is used when installation is at deck level and when smaller blocks are used. The 1574 accepts Midrange blocks.

The 216 features a second cleat for lines led vertically through the base of the swivel. It is frequently used to combine vang or backstay controls in the same swivel base that handles the mainsheet.

The 240 and 241 are simple swivel bases for main and jib sheets on very small boats or for control lines on boats of all sizes.

The 403 is fitted with a double cam for use in two-speed mainsheet systems.

      Y-Flyer mainsheet cleat. Combined with 40mm Sheave Diameter Block, Single/Swivel. Block needed reaming of hole for attachment pin. Other Harken blocks may have been more compatible. Did not need included stand up spring.

      Works like a charm!

        Comments about Cam Bases:

        I installed these on my Int Tempest to replace the clam cleats. I sail alot singlehanded, and putting the jib sheet into the clam cleat was a "fire drill" every time I tacked. With the Harken 240's, I just flip the sheet up to release the lee cleat and tension the opposite sheet as the boat comes around. Simple and much easier and faster. I could have used the H238's instead, and that might have really been better, but I went for the H240's because of single handed the angles are quite different from when I have a crew.
