I have a Jefe Grande. I have heard to get the seat as far forward as possible. My question is, is that true, and does that effect boofing? It seems if it is all the way forward no matter what I do I fail my boof, but if I set it back I nail it more often than not. Help please.
Boat positioning is very subjective, what you feel gives you the results you are looking for is what you should go with. I don't think seat position would make that much of a difference for something like boofing (farther forward might be better because less mass for your abs to crunch up, maybe?). I have found that seat positioning mostly can mess with your tracking, for example if it is to far forward the stern might swing around and if the seat position is all of the way back the bow will be harder to control. I would just mess with it and try to get it dialed before the melt really kicks into gear.
Trim the boat even with your seat position. The bow and stern should more or less be out of the water the same amount. You will need some help. Look at how easy pack-rafts boof without anything behind them. Being too far forward will require a longer more powerful follow through because your weight leaves the lip earlier but the boat doesn't clear the lip any earlier.
If you aren't back endering, I don't see the reason to move the seat forward that far.
