  • How are PERKO Navigation Lights certified for Large Boats Over 20 Meters? (65.5 ft.)
    The U.S. Coast Guard is accepting lights that have passed the UL tests (UL Standard 1104) as meeting the 72 COLREGS and the U.S. Inland Rules for vessels over 20 meters (65.6 ft.). As the first domestic manufacturer to pass UL 1104, PERKO lights can be installed on vessels over 20 meters (65.6 ft.). PERKO manufactures two sizes of lights for the large boat market. The first group of lights is for vessels between 20 meters and 50 meters. The second group includes larger lights and is for vessels over 20 meters (without an upper limit on length).

    A brass tag is permanently affixed to the light indicating the type of light, catalog number, voltage and bulb type to install to meet the visibility requirements. It also states that the light is classified by UL in accordance with the 72 COLREGS. This is the only documentation needed by a vessel in this size range for navigation lights to certify light construction compliance with the 72 COLREGS and the U.S. Inland rules.

    How are PERKO Navigation Lights certified for Small Boats Under 20 Meters built before 11/1/03?
    Lights for these boats must be manufactured in accordance with the American Boat and Yacht Council (A.B.Y.C.) Standard A-16. The primary means of certification recognized in the United States for lights for these boats is through the National Marine ManufacturersAssociation (NMMA) certification procedure. USCG approved lights, as described below, are also approved for these applications.All PERKO small boat lights designed for use on boats built before 11/1/03 are certified under this NMMA Certification Procedure. All lights certified under this procedure are required to permanently carry the mark "A-16" visibly displayed when the light is installed.

    How are PERKO Navigation Lights certified for Small Boats Under 20 Meters built after 11/1/03?
    The only recognized means of certification of lights for these boats is the USCG approval system. This system uses independent, 3rd party USCG approved labs to conduct some of the tests required for the A-16 certification. On all USCG approved lights, the permanent marking USCG 1nm, USCG 2nm or USCG 3nm (depending on whether the light is a 1-mile, 2-mile or 3-mile light) must be visible when the light is installed. Note that certifications may vary with voltage (e.g. USCG approved for 12-volt and A-16 certified for 24-volt).

    How do I choose a replacement pole light?

    Globes come in 3 basic types:
    1. White all-round Full Output allows for full cockpit illumination. Choose traditional or modern styles.
    2. White all-round Reduced Glare helps preserve night vision while under way. Choose clear top coastal or inland.
    3. Bi-Color lights are used on the bow instead of a fixed surface mount light. Choose from models with or without integral white utility light.

    Select a Rake Angle
    Rake is determined by the pole, base and base location angles. Rake is important for all reduced glare lights to insure that light output is correct. The most common rake angles are 0, 5 and 16 degrees. Custom made poles often have nonstandard rake angles. Choose from 0, 5 degrees or fully adjustable versions (Delta and Omega Series).

    Determine if the Key Slot Screw Position is Important
    Most manufacturers insert screws into an upper or lower location on the pole to position the light and hold it properly oriented in the base. The location of this screw varies by manufacturer and model. Determine the key slot screw position needed for the base in your boat or the base you select and match it to the pole you select. All Perko plug in bases accept the upper screw position and all Perko lights have an upper screw. Perko Alpha, Delta and Omega Series replacement lights offer the option to locate the screw in either place.

    Determine the Pole Length
    Navigation rules state that the center of the bulb filament of white lights must be mounted at least 1 meter above center of the filament of the red/green lights. The "vertical height" of a light is measured from the deck of the boat to the center of the light filament. Most pole lights (all of Perko) are sold by their "nominal(or approximate) overall length". Three factors affect the difference between overall length and vertical height. 1) The depth the pole goes into the base is typically less than two inches. 2) The distance from the filament to the top of the light is typically less than an inch. 3) Rake angle can shorten the vertical height by as much as an inch (for bends under 16 degrees). So, as a general rule, the installed "vertical height" will be between 2 and 4 inches less than the nominal length of the pole. Select the shortest light that will insure that the requirements are met after taking this difference into account. Be sure the light is long enough to be seen over any obstructions. If this light is too long to store easily, consider a fold-in-half light for easier storage.

    Decide on a Collar Type
    Some manufacturers use different types of collars to assure that their pole lights are held securely in the base. All Perko lights are shipped with at least one collar (an eccentric collar, a large threaded collar or a small threaded collar). Determine whether a collar is needed for the base in your boat or the base you want to use and match it by collar type to the pole you select. All Perko bases require collars.

    Determine the Number of Pins
    Bi-color lights are available with and without an integral white utility light. Those lights with a utility light require 3 contact pins. Determine if 2 or 3 contact pins are needed for the base in your boat or the base you select and match it to the pole you select.

    Perko Marine Locks and Latches

    How do I determine what kind or Lock or Latch I need for my door?
    When standing outside - If the door opens away from you, then you need a Lock or Latch with a Regular Bevel. If the door opens toward you, then you need a Lock or Latch with a Reverse Bevel. See image below for additional help.

    Perko Marine Battery Switches

    Battery Switch Technical Information
    Battery disconnect switches help manage the overall use of electrical power on board. They are used to connect or disconnect electrical devices from the electrical system. They help to prevent battery drain during periods of inactivity. They allow for a quick and easy way to shut down the entire electrical system in an emergency. An optional key lock helps to prevent unauthorized use of the vessel.

    In addition to doing everything a battery disconnect switch does, battery selector switches permit battery selection (of two or more batteries) for specific purposes including starting engines, running accessories or even recharging. They allow for the use of one or more batteries in systems with one or more engines and facilitate putting batteries in parallel for emergency starting when one or both batteries are substantially discharged.

    All Perko battery disconnect switches and battery selector switches are UL listed, ignition protected and CE approved. This means they have been tested and certified by a respected outside agency, are designed to be used safely in a bilge where explosive fumes may be present and meet all the requirements for use and sale throughout the world.

    Perko battery switches are designed for surface mounting. Standard duty switches have a bright red polycarbonate housing for safety with a large easy-to-turn black knob. The housing of the heavy duty switches are red fiber-reinforced polycarbonate. Selector switches are designed with a "make before break" feature. This allows switching between the, the all and the positions while the engine is running. Models with an Alternator Field Disconnect Feature offer protection for Non-Unitized Alternators should the switch accidentally be turned to the position with the engine running.

    Perko Marine Marinium

    What is marinium? What makes marinium different from other alloys?
    Perko marinium In the early 1960's, a new alloy appeared. First used on large racing sailboats, the new material's high strength to weight ratio coupled with superb corrosion resistance made it an attractive alloy for use on boats. The new alloy was trademarked with the name Marinium shortly after its introduction to the marine market and quickly evolved into a popular line of power boat deck hardware. The line included cleats, chocks, hinges, deck fills, rod holders and navigation lights.

    For many years Marinium was the choice material for numerous quality boat builders. But with the technology that existed in the 1970's and 1980's,Marinium proved to be a difficult alloy to manufacture. Internal rejection rates were high. Attempts to reduce costs only compounded the rework problem. Eventually, in the early 1990's, production of Marinium marine hardware and lights ended. The industry lost access to perhaps the greatest marine alloy ever, until now.

    Using modern technology and casting techniques unavailable to manufacturers decades ago, Marinium has finally been perfected. The high strength to weight ratios and unparalleled corrosion resistance sought after for decades by quality builders is again available, this time with Perko reliability and quality. Marinium offers.....

  • Corrosion Resistance - Equal to or better than any common marine alloy.
  • Strength/Weight Ratio - Highest of any common marine alloy.
  • Weight - Approximately 1/3rd the weight of most marine grade alloys.
  • Finish - Satin Marinized and Chrome Plated.
  • Broad Product Families - Virtually anything we make in bronze can be made in Marinium.
