I have been really successful with my bouy system.
I run a sliding white float on my main rope so it keeps the line snug between water level and the crab ring.
Then I have a round weight (I poured out of lead) that slips over the rope on the slack side of the slip bouy.
Finally, I have a yellow bouy that has a 3' piece of PVC running through it, that stands upright in the water with a flag on the top, and a weight on the bottom (this WILL NOT tip over). This bouy attaches to the end of the slack rope. The slip weight pulls the excess rope between bouys down and out of boaters props way, and the flag waves in the breeze easily seen by everyone.
I have 3 traps and have my last name, and phone number on each bouy. I put a #1, #2, or #3 printed on the sides of the upright bouys so I can easily remember which pot I just pulled, and which is next. I also have psychedelic cow print designs drawn all over my white bouys.
Did my dads the same way, only his uprights are white/red so we can identify the difference between each others rigs.
When we motor up to the upright we just leave it in the water, and use the boat hook to grab the rope on the crab ring side of the slip bouy. Then just pull like crazy leaving the bouy's in the water. The slip weight will pull the excess rope down between the two bouys while the crab ring is being pulled up. Then the ring is dumped into the boat, bait checked and then ring put back down in the water where we choose. Everything settles back down on it's own.
I don't go down and fish, while crabbing, so I spend the entire time tending traps. Going against current I drop each trap in at various distances between each other. Then drift back to the first pot, tend it, drop it and move on to the next and so on. With 6 pots in the water, dad and I shoot for 15-20 minutes of soak time between tendings.
We have a blast and do really well.
Up till this year, we have rented boats out of G-baldi, but now that I have a boat, we are in hog heaven!
