Rick,


With a Clew strap the Vang tension is transferred to the leech with a

I would think that if you have an outhaul car or a slug, then you would not neet
a Clew strap as either of these devices will transfer leach tension to the boom,
if however you have neither then you'll definately benifit from a strap.
