Loop and/or high-strength lashing line
When choosing a Harken Loup
®
soft-attach, be sure the Loup maximum
working load in basket confi guration exceeds the maximum working load
of the block.
When choosing a lashing line, use a breaking load that is double the block's
breaking load to account for strength loss from:
1. Knots slipping or breaking at a much lower load than line breaking load.
Spectra
®
or Dyneema
®
-type lines require specialized knots.
2. Splices slipping or failing due to incorrect type or execution.
3. UV damage increasing with each passing year.
4. Chafi ng seriously reducing strength.
Go to www.harken.com/knots for additional information. If you are not
comfortable choosing line, work with a qualifi ed rigger.
Note: See chart for maximum line diameter that will fi t through mouth
.
Specifications
WARNING! Knots weaken line considerably. Consult qualifi ed rigger
or line manufacturer for advice on securing line. Use high-strength
loops or consult rigger for recommendations on lashing. Using the
wrong line, or securing the line improperly, can cause an accident.
WARNING! Strictly follow all instructions to avoid an accident, damage to your vessel,
personal injury, or death. See www.harken.com/manuals for additional safety information.
= Incorrect. Avoid to prevent accidents.
