Shipping & lead times

We're a small team of boaters and we pack orders within 1–5 business days (no weekend or holiday packing). You'll get an email with tracking as soon as a label goes on your box.

Specialty items — fire extinguishers (dangerous goods) and low-stock or built-to-order gear — can take longer; the product description will say so. On a tight timeline or meeting your boat somewhere specific? Contact us and we’ll work out the fastest way to get gear to you.

International orders ship DDU: local duties, taxes, and customs fees are the buyer’s responsibility. Full details in our shipping policy.

Returns & refunds

30-day returns from the date of purchase. Items must be unused, in the original packaging with all cables and accessories, with proof of purchase.

Contact us before shipping anything back — we’ll send the return form that must accompany your return. Fire extinguisher and lithium battery items carry a $15 administrative fee on returns.

Read the full refund policy.

Ask a cruiser before you buy

Everyone here is a current or past cruiser — we’ve docked short-handed, re-rigged at anchor, and chased 12V gremlins too. Not sure this is the right fit for your boat? Send us your question before you order and we’ll give you a straight answer.

Check fit before ordering

  • Base and pins: match the socket, contact count, pin position, orientation, and spacing to the lamp being replaced.
  • Electrical fit: verify the DC voltage range, polarity requirements, and compatibility with existing dimmers.
  • Physical clearance: compare the full bulb diameter, height, pin length, lens, and reflector clearance.
  • Light output: choose the intended color, temperature, beam pattern, and navigation or cabin-light use.
