It is interesting to recall that an internal closing arrangement, acting in the opposite direction but essentially similar in principle to that which has just been described, had been employed by Kemp^ some ten years previously for sending down large mid-water nets closed and opening them under water. So far the new internal throttling arrangement had only been employed with the young-fish trawl, mounted as already described on a 2-metre ring: whether it could be applied as it stood to the much larger and heavier N 450 with an opening five times the area was a matter for some concern, for to close the N 450 as it would normally be closed, that is by throttling at the canvas band (Fig i,/) where the circumference is 50 ft., ^ Kemp, S., loc. ctt., p. 202.
