The stuff is so low in the water that it can't be picked up by radar.
A debris object would have to be nearly as large as your boat to set
off any radar collision alarm..

Keep a good watch and have a stout boat.. Failing that, have a
collision mat in the emergency locker (along with a plan on how to
use it).

what is a collision mat, in case i need to know at 3am in the atlantic.
