I went up nundah creek the other on low tide. Spotted a lot of pots, with only 4 being sunken and still in use. I reckon that of all of the post that are claimed to be stolen 1% are genuinely stolen. I have never lost a pot. So here is a few tips based on the lost pots I have seen.
1. Tie on good knots. Use a bowline. If you dont know how to tie a know, then learn. I reckon this is the number one cause of lost pots.
2. Use decent rope, dont use that crap nylon stuff you buy from bcf. If you must use it then splice it or use some whipping. If you whip it, put a half hitch in before you whip it. That crap thin rope wont hold a bowline. One of my mates uses splice rope onto locking snap hooks, so he can remove the rope from the pot. Try and use silver rope or telstra rope from the markets. If you can find a floating rope, even better.
3. Dont leave your pots in the middle of a busy channel. This is a surefire way to have a boat cut your line.
4. Use enough rope for the water you are in. If you are in 2 metres of water, use a 4 metre piece of rope. Using shorter rope also means less chance of fouling your prop when retrieveing. If you are in 10 metres of water, then use 12 metres of rope. However, dont use 12 metres of rope in 2 metres of water.
5. Use a decent float. Dont use OJ bottles etc cause they can fill up with water. Use polystyrene. If you want to recognise you pots then use two floats, one being polystyrene.
6. Use a GPS if you have it. That way if you do lose your pot you can try check it on a lower tide or perhaps use a grapple hook to locate.
