Anyone had experience with these? www.burkemarine.com.au/pages/seabrake

I came back over the bar at the narrows at Dunalley after a return trip from the lower east coast of Tas a couple of weeks back. There was very little swell left by then so there was no issue at all. I do tend to use that transit through the canal when there's swell running and I'm off chasing surf. So I wondered about having an easily deployed and recoverable drogue on board if I ever wanted to enter there with any serious swell. I note that they can be repurposed as a flopper stopper too which would be handy in some anchorages (I'm thinking of you Schouten Island).
