175lb magnet, good for little stuff and very easy/non-hazardous to use inside a boat (I use one similar and a 240lb from a sit-in kayak)

750-equivalent paracord - bigger than 550 cord, not so tiny that it'll cut into your hands trying to lift stuff, but low profile enough that you don't have a giant ball of rope in your boat. 1200lb tensile strength, 25 feet runs 10-12 USD.

Gloves; this one is contended by folks. I personally just use good quality nitrile gloves (first link). They're waterproof, thick enough that if you pay attention to what you're doing you can clear your magnet and not cut yourself (don't go ham and just full-fist a pile of fish hooks and razor blades). All gloves are a tradeoff between raw protection and fine motor control; I prefer more control, YMMV. While I'm boating, I also don't have to take my gloves off to paddle, which is super convenient.
For a little more protection, some people prefer the rubberized (sometimes kevlar fiber) work gloves; I hate those. Not that they're bad, I just don't like the bulk, very little fine motor control, and they would suck to paddle with. Instead, I just use a regular synthetic mechanic's glove. They aren't waterproof, but they breathe very well, so they don't hold water (they're the glove equivalent of a mesh water shoe). I can also row with them on, though if long distance you'll want to take them off. If the water is super cold and/or nasty, I'll wear a nitrile glove under the mechanics glove.
