Some calculations could be done. Yes, solar panels would generate some power to partially offset the drain level of the batteries. However, I suspect that any meaningful impact would need a LOT of square footage of deck space for solar cells - way more than practical for you to dedicate to that purpose. Additionally, you change the position of the boat during use, which may reduce the effectiveness of exposure for sunlight. Solar cells are typically fixed location, not bounced across a lake taking high G forces in shock and vibration. Most are not very durable as compared to marine equipment. Got a few thousand dollars and no need for any rear deck space?
You have a total of 3 batteries, and experience very high loads in a short period. A typical solar-charged system has a lot more batteries with a lot more mass & storage capacity than your system (tiny in comparison).
Here's what I did in my garage where I normally park the boat: From a suitable outlet, I ran an extension cord that was suspended across the ceiling using appropriate wiring retainers. The last wire strap that holds it is right above where the charger plug is located on the boat. That dedicated cord hangs down the correct distance right beside the charger plug when the boat is backed into place. Plugging in is as easy as I could feasibly make it. No cord to trip on, or for anyone else to take.
