New boaters are often unaware that electrolysis is something they need to be on the lookout for. Let’s be honest, a lot of us don’t even know what electrolysis is. So let’s start with the basics.
Electrical faults can be devastating. Bad shore power, especially the ground lead, are real dangers. Salt water is an electrically conducive solution and your boat is always in it. All the underwater items on your boat can fall prey to a stray electric current or a bad electrical circuit.
Aluminum boats are at greater risk from electrolysis than a boat not made from metal. The current will flow through the water, stripping electrons from the metal components. The end result is that it will be eating away at them as a result. This can happen very quickly. This kind of chemical reaction is almost unavoidable with an aluminum boat. That is, unless steps are taken to prevent or reduce the damage.
The process of building a large sportfishing boat is not a fast one. From the day a contract is signed to the day the owner shoves off from the dock the first time, two years can easily and quickly pass by.
After a few group photos in front of the hull, one of the yard's large travel lifts was driven over to the hull. Using its slings, it picked up the hull and drove it around to the front of the building, where the Cambeaux's young life had already begun.
The morning of Oct. 20, 2020 was a special day at American Custom Yachts. Work at the 63-acre boatyard came to a complete stop so everyone could observe a significant step in the life of the company's newest project.
V-Bottom: Deep V hulls cut through waves and ride smoothly in chop. They take a bit more power to push up onto a plane, tend to roll or bank in sharp turns and due to the angle of the hull, have less interior volume for stowage or accommodations. Fast, distance fishing boats like center consoles tend to have a V bottom so they can run fast on open water to get to the fishing grounds quickly. more
Semi-displacement hulls combine rounded sections for increased storage and tankage, and flatter hull sections to partially lift the forward part of the hull out of the water, thereby decreasing drag at high cruising speeds. They generate large bow and stern waves and may need high horsepower engines to get on plane. Larger, cruising motor yachts lean toward the semi-displacement design. here
Flat Bottom: Flat-bottomed boats are very stable and can carry a heavier load. They require only a small engine to get on plane but can ride rough and wet in chop or heavy weather. Small aluminum or fiberglass bay and fishing boats often benefit from flat hulls, which have a shallow draft and provide a good amount of deck space both of which are ideal for fishing on calm bodies of water such as small lakes and ponds or slow rivers. more
Pontoon: Pontoon boats ride on (typically) aluminum tubes. Traditional pontoons have two tubes but newer designs have three and are called tritoons. Pontoon boats are all about deck space and make excellent boats for families and entertaining on the water. The newer tritoons can carry large outboards and so they’ve become planing boats capable of towing for water sports or reaching distant fishing spots. here
Drain hoses connected to through-hull fittings should be stronger than clear vinyl hose. For this use, select reinforced rubber hose, sometimes called heater hose. This is the same type of hose used on engine plumbing, and it typically has about three times the burst strength of reinforced vinyl hose. Double clamp all hoses connected to through-hull fittings.

Water tanks typically have three threaded ports, one for the outlet and one for the vent hose, both 1/2-inch, and one for the fill hose, usually 1 1/2-inch. Threaded hose barbs allow for hose connections. The inlet is connected to an on-deck fill. (Be sure the deck-fill has an O-ring to seal out seawater when it is closed.) The vent line leads to a vent fitting high in the boat — above the tank at every expected angle of heel. Be aware that if the vent is not also higher than the fill, it will overflow when you are filling the tank. The outlet connection leads directly to a pump or, in a multi-tank installation, to a manifold or Y-valve.
Supply piping for a boat water system must be non-toxic, non-contaminating, taste-free, and FDA approved for drinking water. If the system is pressurized or will carry hot water, the piping needs to be suitable. The traditional choice for water system plumbing has long been clear PVC reinforced with polyester braid. This same type hose can be used for tank fill and vent connections. here
Manual pumps — hand or foot operated — supply a single spigot connected directly to the outlet side of the pump. A regulating valve is not required; water flow is controlled by the operation of the pump. The primary advantage of manual pumps is that they dramatically reduce water waste, a major concern for boats that spend long periods away from water supplies.
Water pumps on a boat can be either electric or manual. An electric pump pressurizes the entire water system. Most electric pumps have a pressure switch that activates when the pressure drops below a set value--usually around 30 or 40 PSI. Opening any tap on the boat releases pressure and causes the pump to kick on and run until it rebuilds the pressure to the cut-out setting. The pump cycles on and off until the tap is closed. The inlet of an electric pump connects directly to the tank outlet (or multitank valve), and the outlet supplies water to all faucets and appliances.
