I personally would lower the bunks a little (looks that an inch may do it), so that the boat sits evenly and is gently supported by the rollers and the bunks. (Bunks taking slightly more of the weight).
This should make it slightly easier to launch/recover and take some boat weight off the bunks. As has been said - ensure the last roller is within an inch or so of the transom. Otherwise the weight of the engine is able to "bend" the boat about the point of the last roller.
There's weather out there - must be time to RIB!
(Or dive, or ref rugby, or.......)
