Justification of Major Equipment Items The portable, diesel compressor is a back-up for our present air compressor and in addition it can be used aboard the research boat which is being acquired. The use of diesel fuel is desirable both from the standpoint of shipboard use and our efforts for energy conservation in FY 1980 and beyond. Items 2 through 6 are replacements. Efforts are being made to replace high performance outboards with diesel powered work hulls. So far a suitable substitute, with the possible exception of the new Radon hull designed boat, has not been found. Consequently, the Boston Whaler "Outrage" remains our “safest bet" at this time. Regardless of our conversion to more serviceable diesel powered boats, two 17' Boston whalers with 35 hp conventional outboard re motors should be maintained for near-shore work in the southeast corner of the
