I have been following and many discussions both in public and private about the lips on the pad of XB21 boats. It is amazing to me how little information Darris has put out there so far about the optimum height of the lip. Some guys have a lot of lip 0.125" down to about no lip. Some guys have sanded the lip off to achieve better speed or bow rise on deceleration, and some want more lip to handle hole shot better. I thought a healthy discussion with some of your pros and cons on what lip height you have might help some newcomers figure out this "lip question". The lip on my 2018 boat is right at 0.078". To me that gives me a good, all around hole shot, not much nose dive when I let out of it at WOT, and it handles turns fine. Speed? I think it slows me down from what I'd have if there were no lip, but I'm interested more in several things that my boat can provide me and not just speed. Also, what method are you guys using to measure your lip? I used a level and a spacer. When I had the pad perfectly horizontal via the level, I put the level across the lip from back of boat towards the front and leveled the bubble. Then I took spacers and filled in the gap till I had 2 points of solid footing on the level. It was pretty simple to then measure the spacer. There are probably better or easier ways but it worked for me.
