Rewiring a boat means choosing between a bare fuse block and a full switch panel. The four listings here range from $23.58 to $35.00, so budget is not the main issue. The real decision is what each panel can do before you install it: one is a parts-only panel, one is a six-circuit fuse block, and two are rocker switch panels with different extras.
Quick Take
If you need clean fuse distribution, the Sierra FS40560-1 is a straightforward six-gang fuse block. If you want illuminated rocker switches plus charging ports, the 6-gang switch panel with USB and a cigarette lighter socket covers more jobs. The Xhtechnology 4-gang panel is a compact waterproof rocker option. The unknown-age electrical panel is only for parts and not suitable as a working panel.

Product Notes
Sierra FS40560-1 Marine 6 Gang Fuse Block AGC Glass Fuse Panel Boat Electrical

This new Sierra panel is the most purpose-built option for wiring multiple accessories. The description highlights a six-circuit capacity, a common hot bus bar, and a separate ground bus bar for organized wiring. It accepts SFE, AGC, or MDL glass fuses, and the tin-plated brass clips are aimed at corrosion resistance. At $27.99, it gives you a clean fuse foundation. The limitation is that it is a fuse block, not a switch panel, so you will need separate rocker or toggle switches, and it leaves switch control and USB charging to a separate panel.
4 Gang Marine Boat Rocker Switch Panel Waterproof Overload Protector, 12-24V P

The Xhtechnology-branded 4-gang rocker switch panel is the least expensive listing at $23.58. Its description highlights a waterproof front, splash-proof panel, waterproof cap, and an overload protector, along with a DC32V overcurrent protector. This is a good choice if you want rocker switches in a compact four-way layout and need protection against overcurrent and short circuits. The trade-off is capacity: the four-gang layout limits you to four switched circuits, so you will need a second panel if you plan more than four accessories.
6 12V Gang Switch Panel Control USB ON-OFF LED Toggle Rocker For Car Boat Marine

The six-gang panel at $28.49 combines rocker switches with extra utility. It includes two USB ports rated at 5V/3.1A and a cigarette lighter socket, plus a voltage display, all in a water-resistant enclosed panel. The description lists an IP66 rating and DC 12V 20A rocker switch rating, with blue LED backlighting. The panel is approved for CE, DOT, and SAE per the listed attributes, and it is marketed for car, boat, and marine use. The trade-off is space: the panel measures 17.5 cm x 10.7 cm x 7.5 cm, so it needs more dash or console room than a slim rocker panel. It is also a switch panel, not a separate fuse block.
Electrical panel for boat ( Unknown Age/Brand Parts Only To Returns

This listing is the highest-priced product at $35.00 despite being sold for parts or not working. The seller states it is for parts only and that returns or refunds are not accepted. Its manufacturer part number is anc123, but the age and brand are unknown. It could be a source of components if you have a matching old panel, but it is not a drop-in solution for a new wiring job. The limitation is the condition: you are buying an unknown-age panel with no working guarantee and no return option, so it is the riskiest choice for a functional marine electrical setup.
Final Recommendation
If your priority is a clean, dedicated fuse panel, go with the Sierra FS40560-1 Marine 6 Gang Fuse Block. If you want a compact waterproof switch panel at the lowest listed price, the Xhtechnology 4-gang rocker switch panel is the match. If you want one panel that brings rocker switching, USB charging, and a 12V socket, the 6-gang switch panel with USB is the most complete option. The parts-only electrical panel should be left to a buyer who needs the specific parts and accepts the condition.
