We pick up about 30 meters of poly prop fishing net. We were about 35 miles out from Nab twr. 04:45 no wind & poor vis. took just over 4 hours to clear, I had gogles and a syphon tube which improvised as a snokle. A bread knife was used. At one point I was trying to ask the crew member to do something but could not get words out. I was working from dingy half submerged. If going across again I will carry a wet/dry suit. Not Fun!!
