Jono YOU ARE OFF TOPIC!!
This thread is not about life jackets but about a man who killed a few people because he put 13 persons on a boat that was ment to carry 5-6!!!!!
For the record though if the people that hire my boats wish not wear life jackets they can. In Greece the Coast Gurad which is also a regulatory body and the police for the sea will not tell you off and although is recommended is not compulsory
However, I recommend that they do. Nevertheless, if they don't, this is their choice. Master is repsonssible (Carriage of Goods By Sea, Act 1969 & 1971) for his boat, crew and pax. This is the reason I do not hire the boats out if people do not hold an ICC or equiv for less than 3 years. So that they guy/girls that hires the RIB has some sea experience.
However, if you were under 35-38 deg C heat I want to see how you would cope wearing a life jacket. You make me think of the Brits that were dying from heat exhaustion when they were in India wearing these heavy uniforms (because they had to) in 40 and 50 deg C.
BACK TO THE TOPIC,
The fact remains that according to BBC report a few people got killed by someone who was repsonssible for a boat, who ignored any safety related to the boat and he should be punished. Full stop.
