Deck organisers are an effective means
of deflecting halyards and control lines
to winches, stoppers and cleats.
All sizes can be stacked to create double
versions - MWL of the top sheaves must not
exceed 50% of the total block load rating.
Line deflection on larger yachts (depending
on load and angle of deflection).
All Purpose bearing system provides
maximum static load capacity.
Series 40 - halyard and control line deflection
on boats to 11m (36ft).
Sheaves: UV stabilised acetal.
Lightweight design with cheek cut-outs
for easy bearing maintenance.
Series 60 - halyard and control line deflection
on boats to 14m (46ft).
