I heard a rumor that using portage carts
(paddleboy) in Boundary Waters or Quetico
is not allowed.
Any truth to it?
True - In some Cases
From "Boundary Waters Canoe Area Wilderness Trip Planning Guide" USDA – Forest Service, 11/02 Page 5.
PORTAGE WHEELS "Mechanical assistance is only permitted over the following: International Boundary, Four-Mile Portage, Fall-Newton-Pipestone and Back Bay Portages into Basswood Lake, Prairie Portage, Vermilion Trout Lake Portage."
The date seems a bit old. However, this is a document sent to me last month (April 2004) by the USDA - FS.
Allowed only on a few mechanized portage
Not only are they not allowed, but the rocky nature of many of the portages would not be condusive to portage wheels. The BWCA is a wilderness, no mechanized systems allowed. The exceptions are for historic reasons, to provide access to and from motorized lakes at the edge of the wilderness.
