Saphira was doing the same thing. Glued to the boat and would not jump. If she did jump, she would head for shore and not come to the boat. These are a couple things I did with her:
1. I got out my PractiJumps for obedience and started working on jumping. Started at low setting, then gradually raised the height. This taught her the Jump command. When she was jumping without hesitation, I added a little extra to this, by having her jump 5 times before we headed out to the lake. Then when she jumped from the boat, there was major praise and huge rewards. When we returned home from the lake, I had her jump 5 more times.
2. I had to back up with a couple of the exercises and teach her to Come to the Hand. Did this for both Take A Line / Tow A Boat and Retrieve Off A Boat. Without any articles, and with some really yummy treats in hand, I taught her to come to the hand. Started this exercise in wading distance, then gradually moved the boat farther out. Also, my hand was up against the boat, so she could understand that she must go all the way to the boat. Starting this exercise, I was standing in the water next to the boat, not inside the boat. Then transitioned to the articles, again making sure there was a huge amount of praise and a big reward!!
3. Working with the oar, I trained this without the boat, in wading depth water. Threw the oar out a short distance and had her bring it to me. The key here is to work parallel to shore. Do not throw the oar out and have her bring it to you in the direction of the shore. I also would toss it and have her bring it to me in the seaward direction. By doing the short distances at first, I did not need to put her on a long line, as she was close enough that I could redirect her. Once she had this exercise down, then transitioned it to the boat. As soon as she was successful, we had a party!! LOL
These exercises were trained using these techniques in just one day, then we began to work on consistency. She now jumps off the boat, retrieves the oar, and take the line, all with consistently. And if I have to redirect her, I can do this from shore with her all the way out at the boat!
If you do not have a set of PractiJumps, you can easily build a jump by using some PVC. Two sides with holes drilled in to adjust heights, the bar used for the dog to jump over, and a couple long bolts with wingnuts to set the bar on. Also will wan to build feet at the bottom of the side, which will just need a couple small pieces of PVC and a 3-way connector.
