Pros: 9:1 purchase, easy running, cheap, light, low windage, with large diameter hand-held line and no high-maintenance taper.

Cons: possible fouling inside the boom, and limited range of sheeting (~2 foot range of motion).

The system is a good fit for wide-beam buoy racing boats, like the Tornado. Narrower boats probably don't need the high purchase, and would be better served by a conventional non-cascaded system and a smaller diameter boom.
