We have had many threads here on various methods to position a solo canoe's central seat for proper trim.

The following article offers a method using a carpenter's level taped to the bottom of the canoe and a fore-aft adjustable temporary kneeling bar. The freestyler author reminds us that perfectly flat trim in an empty canoe should be the default paddler position because:
"Very early on, FS paddlers learn that all forward and cross forward turning maneuvers will be enhanced if they [intentionally] pitch the BOW of the boat down in the water. Conversely, we also learn that all reverse and cross reverse turning maneuvers are facilitated if the STERN of the boat is [intentionally] pitched down."
