I have read carefully the explanations also. I have always wondered exactly why gliders glide. I define a "glider" as a bait that sinks but has a walk the dog action under water. Good examples would be a phantom or manta. You can make gliders work by weighting them in a variety of ways. One way is to put the weight in the dead center of the lure. I have always thought that by doing so the front and back of the lure would be lighter than the center thereby encouraging the front and back to swing each way on a pivot point, in this case the weight.
Most gliders are weighted in the front and back of the lure. When you jerk a glider the pressure of the water against the front of the lure naturally causes it to swing in the way with the least resistance. Once the lure has swung to one direction and you give it another jerk the resistance is such that it's easier for the lure to swing back rather than continue on it's original path. I am sure there is considerably more physics to this than I am considering but I also believe this explains a good part of it. The entire action is very similar to what makes a crankbait wobble. I do know after testing literally hundreds and hundreds of gliders that some rules hold true time after time.
1. Dense woods are more stable than light woods. By this I mean less belly roll, less likely to blow out when you work them fast. I believe this is because the weight is more evenly distibuted in a glider made from heavy wood. A light wood glider on the other hand will have most of the weight right where the lead is.
2. Round gliders "glide" easier and further than flat-sided gliders.....a manta being a good example, huge glide, very stable.
3. Longer lures generally glide considerably further than shorter lures.
4. If the nose of the glider is too narrow it won't glide.
5. If the wood used to make the glider is too narrow it won't glide
6. If the tail is too wide, it won't glide (the same can't be said for women).
As for the hump, it seems to reduce the glide length. Think about a magic maker or similarly shaped gliders, they dart left and right very quickly but the glide length is very short. Long thin gliders on the other hand without the hump have much longer glide distances.
How did we get started talking about gliders? I thought we were discussing swimbaits? lol.
