Carol and Matt,
How do you reconcile Erin and Hig's "self-rescue of a packraft and heavy pack" approach with Roman's?
Roman says it is best to get upstream of your boat mid-point and the heavy pack lashed to your bow. Reach across the boat and pull the downstream edge towards you to right the boat and pack before getting back in.
Erin and Hig say, it is extremely difficult to right a packraft with a heavy pack lashed to the bow. They suggest having a light tether between your pack and packraft plus a quick release lash strap. After flipping, you enable the quick release of the tethered pack so that it floats adjacent to the packraft connected via the tether. You then orient the boat and enter the same way that Roman suggests.
In turbulent white water flips, in combination with a heavy pack, I have used Erin and Hig’s approach successfully but haven’t tried Roman’s approach to compare them.
