We were transiting to Horeshoe Cove in Sandy Hook Bay for the night. We had electronic navigational tools and maps which did not show any hazard or fixed objects in the area.   We were at about 5 knots and we did not see fish traps or any lights on them.  They were not listed on any maps or charts.  we saw them last minute and tried to take evasive action without success.
