Please don't missunderstand.
We have RADAR, AIS reciever, DSC Radio, Chart plotter, moving map software on our laptop . . . honest - have them and use them all, but, we absolutly love to cruise the coast of Maine and there you just have to play the "lobster trap float polka"! No choice.
More than five weeks there this past summer and we only picked up one, and I got it off without using a knife at all. I really really try to avoid costing a lobster person their gear.
And all possible because we try our best to avoid stuff that wants to wrap around our prop.
