This was a quick concept drawn following a recent visit to Cape Town, South Africa. The client, who operates charter boats from the Victoria and Alfred Waterfront development, was planning an addition to his fleet of charter boats. In this case it was felt that extreme speed was not really and issue due to the fact that suitable sea conditions are rare in Table Bay and keeping fuel costs within reason makes good sense.
In one mode the vessel can take around 30 passenger on 1 to 2 hour trips around the harbour and also a few miles along the beautiful Atlantic Seaboard of the Cape Peninsula. Stripped of the some (or all) of the seating will create larger deck spaces available for other utilisations such as carrying film crews etc.
The collar in this case would most likely be foam with a polyethylene coating, instead of the typical inflatable Hypalon tubes which have given rise to the term’s RHIB or RIB. So in a sense, although this is not a RIB, the overall styling showing circular “pontoon” sections of the collar lends itself to the name.
Various powering and propulsion options would be suitable, depending on budget, location of operation, availability of maintenance etc. Approximately 700 hp would be required at full payload to top 30 knots. Cruising speed would be in the mid – 20 knot range, still quick enough to be fun whilst not needing shock-mitigating seating.
