MarineBuzz brings us photos of the M/V Bohai Challenge, being launched on what appears to be Yokohama Fenders (official they’re not Yokohamas). They tell us;
Qingdao Yongtai shipping supplies co.,ltd has come out with a novel product called Intense pneumatic tire for ship lifting, loading and floating. These highstrength pneumatic tubes are useful in cargo boat launching and landing, clog lifting and moving, sunken ships salvaging and stranded boats saving. The product is suitable to launch ships up to 7000 tons.

Also, in researching this post, I came across an excellent transcript from a Nautical Institute presentation by Captain Eric Southworth, Director of FenderCare. He tells us;
Originally, Japanese ships used dead whales as large fenders. They were replaced after WW2, when the Japanese tyre manufacturer ‘Yokohama’ was asked to come up with a suitable man made alternative, hence the birth of “‘Yokohama” fenders. Before 1975 wheel type fenders were commonly used in positions 2 & 3, with “Yokohama “pneumatic fenders in positions 1 & 4. (All four positions are along the parallel midbody). Smaller secondary fenders may be used to protect the bow and stern plating from inadvertent contact during mooring and unmooring.
