Still a couple of months to go until boating season

Couple more things I am thinking about doing.
Add a keel guard and rubrails. No damage yet, but just a matter of time.
Make a bow dodger. I need some shade for those hot summer days when my wife comes along. It could be shelter during a sudden downpour too. I don't think I like bimini tops and a tee top is not an option for me.
Also need to buy a battery charger. Need suggestions.
