Does anyone have experience using a clump weight attached directly to the tether? I’m curious about using a kellems style grip directly on the tether to attach a clump weight (~30 - 40lb) for our operations in 30-50m water. This would allow us to better manage our cable with fewer people on board our small surveys.
The specs say the tether has a breaking strength of ~300lb and working strength of ~80lbs. I’m mostly concerned with the integrity of the tether jacket with a grip wrapped directly around the outside. Secondarily, I’m concerned whether the 300lb limit might be exceeded when the boat heaves in small waves or under tow.
Hi @ryan-fields -
I’ve attached clump weights ranging from 10-20 lbs, simply with a “double wrapped” zip tie. Twice around the tether, once around the weight. For only 30-50m, 30-40lbs seems quite excessive - are you trying to overcome very strong currents?
I’d definitely take care to lower the weight to the bottom quickly, to avoid any jerk loading on the tether, but reaching 300lbs seems unlikely…
Thank you! I think our weights are actually 20 and 30lb now that I look at them. We’re in coastal Oregon, so I’m expecting decent levels of current, but will try the lighter weight at first.
