SYM 7 AutoTrawl - Winch Dynamics
Is Winch Dynamics Important to You?
With SYM 7 Winch Dynamics you can easily and quickly select the response that is most suitable for your current sea and bottom conditions.
SYM 7 makes it possible for the skipper to choose appropriate winch response for varying towing conditions. This will reduce the fuel consumption when the weather is good and secure the highest catch rate when the sea gets rough.
SYM 7 Vessel motion can be set up to assist the skipper on what Winch Dynamics setting that should be selected for the current and measured sea condition
Rough Weather
FAST or MEDIUM setting is required in rough weather. The winch speed must be sufficient to compensate for vessel movement to keep constant pull on the trawl doors. This is important to keep the trawl stable and to keep up the catch rate in rough weather.
Calm Sea and Good Bottom
CALM or ECON mode can be used when the bottom conditions are good and the risk of a fastener is low.
Rocky Bottom
It is important to have sufficient winch power available when towing on the rocky bottom. Use FAST or MEDIUM response to enable the winches to withstand fasteners, and recover the net when it comes loose.
