A couple of suggestions.
A Lorwance chart plotter with the Western Lakes Navionics card. Or something similar.
For good economical lighting, I mounted a Light that I purchased from a local Auto store $145.00 approximately for the light. Its was made for ATVs. Blue light, high powerd hallogen bulb. All composition for rust free maintanence. Stands up to shock really well. I may add a second one of these. The first time I turned it on, after working late into the evening mounting it, the families children from accorss the street all came running to their bedroom windows to see what was happening. What it was, was a really BRIGHT light!laugh hyst When returning to the dock area or slips at night, I have lots of light from this light. Its was more than needed for that purpose
For deck Lighting, I wired in a plug for a spot light for looking around. For turning on and leaving on, I have some single bulb interior RV lights that you can purchase for under $10.00 each. I wired two of them to keep the light on the deck and out of my eyes. Put them under the place where they will not get hit with alot of rain. I never had a single problem with these and their appearance is acceptable. Look at the price of what is called dock lights and deck lights. You'll head to the RV store in a hurry.
These combinations are working for me, really well. If you want to really light up your world, plan on spending big bucks. Water absorbs light, so it takes alot of illumination to over come that from a boat. To light up the objects on the water, or the docks you are returning too, that is an easier task.
I love the chart plotter. I can run in the pitch black dark of the night without my light, (not recomended), and get where I want to go. A lighted compass for a back up is a good idea.
I have left in the dark and returned in the dark. Nothing like a full day of fishing.tongue2
