This adjusting car
replaces separate blocks and a connecting member. Tandem sheaves eliminate
severe flexing of the backstay, providing a neat, thoroughly functional
fitting. The 38 Series with Delrin sheaves is intended for boats under 30ft.,
while the husky 39 Series with aluminum sheaves is intended for boats up to 40
feet.
Note: For maximum car release, use a 1.5 to 1 ratio
between backstay base width and car height. Example: If backstay width is
5’-car height should not exceed 7 1/2’ to 8’ in height off deck. Higher ratios
may require manual release with aid of boat hook, etc. |
