OP said "New boat owner". If you bought from a dealer, take the list to them and see if they'll offer a package.
As you use the boat more, preferences may change. Don't overbuy just because it's fun.
Put your list on Amazon. Maybe you'll get Father's Day presents? Throw a "Christening Party" and let folks know where you're registered. Duplicates are good. Two anchors & line, two charts, etc.
Using a local dealer means easy return/swap. Parafunalia is nice about this, even if you special order. Maybe a clerk who will say "Not many people buy these, try this" Sometimes upselling, but often good advice.
What's your vessel name? You can get embroidered stuff at the NE Boat show while you are at the show. Also, almost anything with the name on it from
