You can buy their boats with confidence. If this is not the case, your hard-saved money might be at risk. If you are looking towards one of the Avon dive boats and customising it to suit, you need to ask about a suitable demonstrator. This year the parent company is supplying the RIB and leaving it to the dealer to fit it out to suit his target market - dive boat, sports boat, work boat etc. You may have to travel to get a ride, but the demo will be appropriate to your sport.
Most companies report full order books.
Some have lead times of several months, so it clearly pays to plan carefully and order early. We do not cover those craft we consider to be poorly constructed or unsuitable as dive platforms, though omission does not automatically denote disapproval. Engine quoted above is middle of appropriate range. Boats not available separately. The Viking has 1 year warranty, remaining boats have 3 years.
