Even with life jacket you guys are right about getting out being an issue.
After a MOB at Wroxham Broad, a small lady with three of us to get her back on Brilliant, I did some hard thinking. We now have a floaty line with caribiner on one end to attach to life jacket, and two more on blocks to attach to the boat with line fed through ready for use. This gives a better pulling power and in fact allows the casualty to help with the pulling as the end can be fed back.
Having LJ s on gives you a bit of time to get this set up and the ladder over the side once you have brought the MOB alongside with the ordinary throwing line or whatever.
No JL then ‘float to live’ as the RNLI says.
