Squid, next time your running with 6 adults like that you can do some great testing by moving folks around. Tuff in the winter, but I bet you would have knocked that lip down with one or two moved to the bow.
I find the SAN wake so sensitive to people that the wake shape changes a lot when you add 6 people to a perfectly balanced loaded up boat, it can mess up the wake. This does not seem to be as much an issue on the VLX or the X2.
In my SAN I am running:
In addition to factory large tanks,
240 lbs under the rear seats around the batteries
240 right side rear
240 Left side rear
480 bow forward
280 walkway
120 loose in cabin to balance
Usually run with just 2 or 3 in the boat plus the rider.
If i was to run with 6 people in the boat I would need to off set that with more bow weight or empty the rear tanks a little to pull the lip you mentioned down. Takes at least 23.5mph to get anything clean with that weight on my boat.
