Bill Davis and Ed Crafton founded Wellcraft Marine Corporation in 1955 in Sarasota, Florida. Initially, the company built wooden boats 14-17 feet long, as well as smaller 12-foot Skits. In the early 1960s, Wellcraft began producing custom fiberglass boxes, a true innovation at the time. These were small, including 23-foot-long cabin boats with deep V-hulls. Almost immediately after the company started production, it started exporting boats to foreign markets, where customers quickly appreciated the boats’ quality, good looks and practicality. Wellcraft. In the 1970s, the yard produced more than 20 different models, including trimaran-hull yachts, which proved to be very enjoyable sailing.

It was produced in collaboration with the creator of the Wellcraft Scarab brand Larry Smith. Thanks to the Scarab 38 KV, which appeared in the popular series Miami Police: Morale in 1984, sales increased by 21% during the year.

For its 40 years, Wellcraft has built more than 250,000 boats. After several changes of ownership, Wellcraft, like Scarab, came under the control of the French Beneteau group in 2014.

Wellcraft is headquartered and manufactured in Cadillac, Michigan. The brand has a wide network of dealers worldwide.

Wellcraft offers pleasure boats, water sports and fishing boats from 18-36 feet. The boats are equipped with powerful marine engines. The company’s website offers a simple configurator to choose models and options before ordering.

Wellcraft boats are distinguished by their speed, maneuverability, efficiency and suitability for sailing for various purposes. The deep V hull is ‘closed’ for a smooth ride in any sea state. The perfect maneuverability and control of Wellcraft boats is a special pride and years of know-how of the yard. Multiple saves and simple conversion solutions come in handy in every mission. Insurance and breakdowns can save your boat! In this article, co-founder Nigel Calder explains in detail why overcurrent protection devices (OCP) are so important and how to install fuses and breakers on your boat.

From time to time, I have shown what happens when I use 12 gauge wire (AWG 12/4mm²) to make a dead short on a 12V battery. When I flip the switch on the wheel, the wire vaporizes, filling the entire room with a cloud of foul smoke and forcing everyone to get out of there as quickly as possible.

I don’t recommend that anyone try this test, but I often see what, in fact, is a test device like this on the boats I inspect. It is done by wiring one or more pieces of equipment directly to the ship’s batteries without installing a fuse or overcharge protection (OCP) on the positive battery connection, thus setting the stage for cable breakdown. All it takes to ground things is a short to ground, as can happen if the insulation is damaged, or a terminal comes off and makes contact with something grounded, or someone installing a new cabinet puts a screw in the wires.

In complex systems, it is difficult to verify that each director is protected. Potential fire hazards are a common sight even on brand new boats.

Unfortunately, the abundance of electrical circuits in modern boats has greatly increased the likelihood of unprotected circuits compared to boats of a few years ago. Worse, they are older boats that have been retrofitted with extra wheel covers. And, usually, worst of all are the boats that have their own wires.

A common culprit for system monitoring devices is small meter voltage sense leads: where they connect to the positive side of the system, they need the right fuse (usually 1 or 2 amps).

Insurance statistics from Boat U.S. shows that 55% of ship fires are electrical in origin, with more than half caused by short circuits, most of them in direct current circuits. By comparison, engine overheating causes 22% of fires, and fuel leaks (almost all in gasoline-powered boats) cause 8%. So be careful: If you or someone else adds enclosures to the boat, make sure they are properly secured.

Better yet, create a complete wiring diagram for the boat and make sure all current circuits are properly protected.

We teach you in detail how to create such a wiring diagram for your boat in our Boat Electrics 101 online course.

I am also amazed at how many unmaintained or poorly maintained boats with one or more wheels come from boat builders. (Note that circuits used only for data transfer between electronic devices and wires for temperature sensors are the only ones that do not require OCP.)

A popular misconception is that fuses and circuit breakers should be rated for the current rating (inrush current) of the equipment in the circuit. This illustrates a misunderstanding of the purpose of the jumper: to prevent the wires in the circuit from loosening in the event of a short circuit. Since the most heat in any circuit will be developed by the part of the wiring with the greatest resistance (ie, the smallest circuit), a surge protector is sized to protect the smallest circuit in the circuit. This includes wires on the negative and positive sides of the circuit.

Note: This test is for DC systems with the negative side connected to ground. Double-pole insulated systems, which you can find on some metal boats, have different requirements, such as double-pole breakers on all leads except the main battery cables.

For example, if a GPS, which draws minimal current, is connected to a circuit with 12 nuts (4mm²), the mounting device must be sized to protect the tracks, not the GPS, from melting. Something like a 20 amp fuse or switch will do. Separate protection (usually a fuse, maybe as little as 1 amp) is needed for the GPS or other equipment in the circuit.

If, however, a breaker in the switch protects a circuit for one load and the protection required by the load is less than that required by the terminals, the breaker may always be used to protect the load, up to about 5 amp, be great. usually the smallest available conversion. If, on the other hand, the same approach is used for a fault that protects multiple grids, the sizing is more complicated. Two factors must be considered: (1) the total load of all electrical equipment served by the outlet and (2) the smallest current-carrying capacity (power) to be maintained. The breaker should be sized based on the overall load reduction or current carrying capacity of the smaller conductor.

Fuses & Circuit Breakers: Overcurrent Protection (ocp) On Boats

If one switch feeds another auxiliary panel or fuse block, and if all conductors from the second panel or fuse block to the individual devices are protected by their switches or fuses, the only conductor that must protect the first switch is the cable feed. auxiliary table. In this case, the fault should be evaluated according to the overall load reduction on the auxiliary panel or the variable current carrying capacity of the supply panel. The same design approach governs the measurement of fuses for battery cables. The fuse usually protects up to the main switch on the board, so it is sized to protect the smallest switch on the board.

The wires on the positive terminal of the used boat are installed incorrectly and the OCP is not visible. There are many such installations out there and they are all fire hazards!

The basic rating for fuses and circuit breakers is the amperage they are designed to trip or break. Hidden in the fine print is another ampere known as Ampere Interrupting Capacity (AIC). This is usually in thousands of amps and tells us the maximum current that the device can safely cut if it is struck by a large current such as a dead short in the battery or a lightning strike. If the current exceeds the AIC level, the device may crash or create another path of the controller and not do its job.

ABYC requires AC and DC circuit breakers to have a minimum AIC rating of 3,000 amps in most cases and 5,000 amps in some. ABYC’s E-11: AC and DC Electrical Systems on Keys has detailed recipes. The main fuse in any relatively large battery bank should have an AIC rating of at least 5,000 amps and, in some cases, more. (For example, lithium-ion batteries can be efficient
