+1for Bung
except it was a hardboat and VERY nearly sank it!!
Many years ago had a little 13 ft Dory with unbraked trailer recovered it one day using rope towed it to the top of the slip disconnect rope from car reversed back to hitch just a little bit to far touched the trailer and off it went back down the slip
shat myself at the time someone could have been badly hurt and/or boat damaged but thankfully got away with it and learnt valuable lesson!!!!!!!!
Swilled my manual lifejacket off in the kitchen sink only to discover it was automatic afterall!!!!
