Just wanted to remind folks that on this web site's store we carry the Rick White's Power Righter. While it makes no claims to righting a boat solo, it does make righting the boat quick and easy with fast stowage of the unit after the boat is righted.
For boats that are normally sailed single-handed, it works fine by oneself (I use one on my Taipan 4.9 Uni) and the pix on the website show my son and his friend righting a Taipan 5.7 -- they weighed around 280 lbs.)

Ad Police: forget it -- this is my site.
