The PROFURL motorized headsail reefing-furling systems are designed to be fitted over the existing
forestay.
The following components are identical to a PROFURL manual system:
- extrusions and connectors. The gear motor replaces the drum mechanism found on a manual PROFURL
system. Please check assemblies of these components in the standard drum Installation Manual, pages
18 and 19.
- halyard swivel (pages 20 and 25) and Wrapstop (page 17)
FITTING THE MECHANICAL PARTS
ADAPTATION OF THE ORIGINAL FORESTAY
The toggle (47) - please see page 2 - supplied must be attached directly onto the stemhead
chainplate and to the bottom eye of the forestay. No other fitting should be inserted between the
toggle and the chainplate.
I - ORIGINAL FORESTAY WITH EYE AND ADJUSTMENT PLATES
Accurately measure the overall length pin to pin of your forestay.
• If an eye and adjustment plates are fitted please mark the position of the eye between the plates.
• If a turnbuckle is fitted, please mark the adjustment position of the turnbuckle : this will maintain your
existing mast rake and forestay tension.
5
ADAPTATION OF THE FORESTAY
a) The adjustment plates should be completely removed
b) The toggle supplied with the system should replace the adjustment
plates.
• Should the forestay be too short: fit the adjustment plates or a
standard toggle at the top of the stay, or fit a new forestay.
• Should the forestay be too long it should be shortened to the
correct length and a new eye swaged at the bottom of the stay.
