They forgot to bring them
People were only outside till just outside the marina then we all had to go inside whilst the bloke in survival suit stayed outside.
The guys who run the boat believe the tubes are a major advantage in very heavy seas, giving the boat a lot of support making manoeuvres safer.
The demo run we had was just great. The two 1000hp jet drives gave the skipper fantastic control and us a trip in a RIB quite like nothing I have tried before.
To be honest, knowing we were in very safe hands, inside a boat that self rights and being whizzed about by a skipper that had plenty of concern for the safety of his passengers, I would have no hesitation of putting me and my children on the boat again without lifejackets (it's not quite in the same league as a normal fast rib ride).
