If your trying to gillnet panfish your better off going with a size that would catch just in front of the dorsal fins and the belly, they were probably bouncing right off that 2in unless super small fish. Tighten your hangings up alot, that is a mess in the works as far as having the leads fall through or corks falling back into the large hangings. You don't want to over stretch your hangings. Hanging on the half is pretty common . Say 3 in mesh swinging 4 meshes = 12 divided by 2 = 6 in ties swinging 4 mesh each tie.
Ok so when you say
3 in mesh swinging 4 meshes
Sorry if it sou d's stupid just really trying to get this terminology down lol.
Now back on the float and lead line. How do you know what you want ?
So what I'm reading is your main sizes of float rope are #12-#32 with buoyancy per yard being .9oz-10.5 oz.
And your lead rope is sized #20-#85 the sizes being the weight of 600 feet of lead line..
So I take it (and this is just me figuring) you would calculate how long your net would be then calculate your total buoyancy in yards (like a 20yd net with a #16 float rope at a boyancey of 1.7oz per yard. 20'÷3= 6.6 yards ×1.7 oz =11.22 oz of buoyancy for a 20yd net.
Then you would calculate the weight if your lead line so say #30 is 30lbs for 600 feet which is 200 yd and your net is 20yd. 20 yd is 10% of 200yd and there's 30lbs of lead per 200yd so you need to know what 10% of 30lbs is so if my math is right you should have 3lbs of lead line..
So if I wanted a sinking net I would use these calculations to find what's gonna have more weight then buoyancy and if I wanted a floating net I would do the same but just to figure what I need to pick the lead off the bottom .
Am I kinda in the ball park here or am I waaaaaay over thinking this ?
Seems if your in still water the lead line dosent later as much as in current
