Frequently Asked Questions

How does the wing handle in rough conditions?

As with trawl doors there is a limit to what is safe. The weight of the wing is similar to the pair of trawl doors you would be replacing but the net is attached to the ends which dampens the pitch and roll. The wings can be quickly retracted and set into the transport rack on deck. This is very helpful when running from bad weather. On anchor the net can be double bit to pick up on the wing. This dampens the motion even more.

Does the wing need to come aboard the vessel during a net change at sea?

No. The wing will be retracted half way in on the trolly cable. Both ends of the wing can be rotated in over the side of the vessel and the net changed. If in rough conditions the inside end of the wing can be pinned to the bull-works to eliminate movement. The only time the wing is brought aboard is in very rough conditions or going home.

What happens when I hit a wreck?

Many times the wing will bounce around the wreck and the towing boat will not stop. If the wing does become hung the opposite wing and net can be retracted and hung in the rigging before retracting the hung net. Another plus to the wing is that when it comes directly above the wreck the wing will slip off the wreck. Since the net is always held open it doesn’t have the tendency to collapse around the wreck. Nets and the wing can be damaged as with any trawl system that enters the water. An old saying is, “It’s not yours until you get it back on the boat. While it is in the water it belongs to the sea”.

Will I lose production?

Depends on what your vessel is pulling now. We attempt to base the size wing on how much lead or bottom line spread you would create with your trawl doors. Typically in perfect conditions a pair of trawl doors will open to 75% of your head line or cork line length. 100′ of net would be 75′ of lead line spread.

Another consideration is the type of environment you are shrimping in. Hard tides will affect the spread of trawls with doors same as deep water and high top line nets. The wing has little trouble with hard tides or tall nets. In the deep water configuration the top line can be lowered to as little as 12 inches off the sea floor. This equals increased speed over ground at a very low RPM. Fuel savings and cleaner catches should more than compensate for any loss of production.

How hard is it to learn how to use?

Not difficult. Each wing is designed to fit the host vessel. Too large of a wing is difficult. You or your crews can be trained on our host vessel prior to delivery. We will teach how to handle the wing in the real world environment. It is not our intention to deliver a wing to your vessel and say, “Here you go, have fun!” We have been at sea with this equipment and know what to do and what not to do. This information will be yours to use.
