About Marine

Salt is the enemy on a boat, and it does not care what the product cost.

Every connector, every lug, every switch and every lead on a vessel lives in air that is trying to corrode it. A joint that lasts ten years in a caravan lasts two seasons at sea if it was not made for it. So the rule for marine gear is not about capacity or output. It is about what happens to a contact face when the salt gets in, so check each product's ingress rating and the maker's guidance for marine use.

The power system on a boat is built around that. A house bank separate from the start battery, with a relay or a charger between them so the fridge cannot flatten the engine. AGM where simplicity and cost matter, lithium where weight and cycle life do, and a management system that knows what a dual purpose battery is for. Fusing close to the bank, in holders that keep the water out. A monitor at the helm, because voltage is the only thing you cannot see.

Cooling and ventilation are different on the water. A fridge has to hold cold with the boat heeled, which is where a DC compressor beats absorption. A cabin fan moves air where a hatch cannot be opened. Lighting has to survive spray and show up against a reflective surface, and a dimmed or coloured mode matters at night when bright white light kills night vision.

Check corrosion and ingress ratings first, then capacity and output. Not everything here is marine rated, so read the listing before it goes aboard.

FAQs

Marine FAQs

What kind of marine gear does Roam Gear sell?

Roam Gear provides a range of 12V and 24V components specifically designed to handle the salt air and high humidity of marine environments. Our selection focuses on the electrical foundations required for a safe boat setup, including tinned copper cabling and sealed power distribution gear. These items help prevent the corrosion that often leads to system failure on the water.

Our catalogue features high output LED boat lights that are fully sealed against water ingress, alongside house battery storage solutions for running fish finders and accessories. We also stock specialized plugs and connectors to maintain secure links in your wiring. This curated range helps you build or upgrade a system that performs consistently during long days on the water.

How do I set up a reliable dual battery system for my boat?

A dependable dual battery system on a boat requires a clear separation between your engine starting battery and your house battery. This isolation prevents your electronics, fish finders, and lights from draining the power needed to start the motor. Most marine setups use a Voltage Sensitive Relay, or VSR, to automatically manage the charge from the alternator while protecting the primary battery.

Using marine grade tinned copper cable is critical for these connections to resist the corrosive effects of salt air and moisture. This maintains a low resistance path for the current and helps prevent electrical faults during heavy use. Browsing our selection of 12V deep cycle batteries provides the right foundation for your house bank, while high quality plugs and connectors maintain secure terminations across your system.

What is the best type of house battery for my boat?

Lithium Iron Phosphate (LiFePO4) batteries are the most effective choice for a marine house bank because they provide a stable power flow and high usable energy. Unlike traditional batteries, lithium units can be discharged almost completely without damaging the cells, which is a major advantage for running electronics and lights while anchored. They are also significantly lighter, helping you maintain the trim and performance of your boat.

For smaller vessels or occasional use, an AGM battery remains a practical and spill proof alternative. These batteries handle the constant movement of a boat well but provide less runtime and a shorter service life than lithium options. Both types are sealed, which is a safety requirement for marine use to prevent the venting of dangerous gases in enclosed areas. To find the right storage solution, you can browse our range of Lithium Deep Cycle Batteries or explore our AGM Deep Cycle Batteries for a durable setup.

How do I know what size solar panel I need for my boat?

The panel size you require depends on your daily power consumption and the physical space available on your deck or cabin roof. Start by calculating the total amp hours used by your electronics, fish finder, and lighting over a twenty four hour period. To keep your house battery healthy, your solar setup should be able to replace this energy during the average four to five peak sun hours available each day.

For many small boats used for day trips or weekenders, a panel between 100W and 160W provides enough charge to maintain a house battery while anchored. If you run a 12V fridge or spend multiple nights away, you will likely need 200W or more to manage the extra draw. Because boats often have limited flat surfaces, choosing high efficiency monocrystalline panels is the best way to get the most power from a small footprint.

Should I install a glass or flexible solar panel on my boat?

Choosing between glass and flexible solar panels depends on the available mounting surface and your performance needs on the water. Glass panels are typically the most durable choice for flat, rigid surfaces such as a hardtop or targa arch, where they can be bolted down securely. This rigid design allows for a small air gap underneath, which helps manage heat and maintains charging efficiency during hot Australian summers.

Flexible panels are a better alternative if you have curved surfaces or want a low profile look, as they can be bonded directly to the deck or cabin roof. This installation method helps prevent snagging fishing lines or gear while you are moving around the vessel. Browse our selection of high output 12V solar panels to see which format fits your boat, or pair your choice with a professional solar controller to protect your house battery bank.

Does Roam Gear offer LED lighting for marine and boat applications?

Yes, we provide a range of LED lighting specifically engineered for the unique challenges of the marine environment. These lights differ from standard 12V lighting because they use corrosion resistant materials and fully sealed housings to handle constant exposure to salt air and moisture. This specialized construction helps prevent the internal circuitry from failing when exposed to heavy spray or high humidity on the water.

Our selection includes high output units designed for deck illumination, cabin lighting, and focused spotlights to improve safety during night navigation or pre dawn fishing trips. These LEDs deliver bright, clear light with very low power draw, which helps protect your house battery levels while anchored. Browse our collection of LED boat lights for watertight options, or explore our LED lighting accessories for the wiring and switches needed to complete your install.

How do I maintain an optimal battery setup for my boat?

Regularly monitoring your state of charge and providing a consistent maintenance flow is the best way to maintain an optimal battery setup. You must keep all connections clean and free from salt spray to prevent corrosion from increasing electrical resistance. Using high quality tinned copper cabling throughout your boat helps protect your system from the high humidity found on the water.

When your boat is not in use, connecting a smart battery charger will help keep the cells at the correct voltage. This prevents the permanent damage that occurs when batteries are left partially discharged for long periods. Tracking your daily power draw allows you to adjust your usage and prevents you from running out of energy while anchored.
