Tranona I fear the MAIB records you repeatedly quote as justification do not give the full picture. I've located the Thames estuary incident. Yachting Monthly Dec 04 p72-74 ('learning curve') I suggest you read it: Father and son in an apparently well sorted yacht strike an object in the outer Thames at night ( in June) - boat starts to rapidly sink, 5 - 10 mayday calls gained no response two flares likewise despite ships only a few miles away. Stepped up into the liferaft at 0210 BST, fired flares when commercial ships in the vicinity but none respond, eventually recovered at 1010 BST. Without a liferaft these two would be dead (despite being in coastal waters etc etc). Incidents where a liferaft saves lives in coastal situations do occur - would you agree??
