A modular block has lad wye plates configured on opposing sides of the block that carry the load from an axle fastener to load fasteners coupled to the eye. This configuration of the load wye plates enables the other components, including contact surface components such as the sheave, sheave wheel, side plates and bushings to be made of lower weight materials, such as polymers thereby increase the load to weight ratio of the modular block. Ultrahigh molecular weight polyethylene (UHMWPE) is a preferred material for the contact components and high load capacities are realized with these polymeric components used in conjunction with the load wye plates. Also, the use of non-sparking polymeric or composite materials is required in some applications to prevent fire or combustion.

A seine net position measurement system utilizes a plurality of sensor modules coupled to the seine net to determine the seine net position by recovering seine net position data, such as depth data, upon retraction of the seine net to the boat. The sensor modules may be configured proximal to the bottom of the net or the leadline. A depth profile of the net, as well as a rate of sinking of the net may be determined from the position data. The sensor modules have a sensor wireless signal transceiver that transmits a wireless signal to a wireless signal transceiver that sends the data to a computer for processing. The computer may be on the boat or part of a cloud computing system. This system is economical and enable a large number of sensor modules to be used to provide better accuracy of the net position.

Seine net position measurement system and method of determining seine net position

A seine net assembly utilizes buoyant seine net purse rings that float above the leadline and therefore reduce the risk of the purse rings getting snagged on the bottom of the body of water. An exemplary buoyant purse ring may have a specific gravity less than 1.0 and preferably, between 0.08 and 0.96. It is desirable that the purse rings float but not be so buoyant that they cause the leadline and therefore the leadline end of the net to float. An exemplary purse ring is made out of a polymeric material such as polyethylene and most preferably ultra-high molecular weight polyethylene (UHMWPE). A polymeric purse ring may have a ring wall with a rectangular shape designed for durability and tighter packing. The width of the ring wall may be greater than the thickness.
