Cal June Buoys

<h3>About Cal June &amp; Jim-Buoy</h3><p>Cal June, the North Hollywood, California-based company behind the iconic <strong>Jim-Buoy</strong> brand, has been a cornerstone of marine and pool safety for more than three decades. With a catalog spanning everything from life-saving ring buoys to robust mooring systems, Jim-Buoy has earned the trust of both recreational boaters and commercial maritime operators around the world.</p><p>What sets Cal June apart is an unwavering commitment to quality construction and safety certification. Many Jim-Buoy products meet or exceed U.S. Coast Guard (USCG) standards, and several carry SOLAS (Safety of Life at Sea) approval — making them a go-to choice not just for weekend boaters but also for commercial vessels, docks, and marine facilities that demand the highest level of reliability. Materials are chosen for longevity on the water: closed-cell foam cores resist compression and moisture, durable vinyl and polyethylene shells stand up to UV exposure and harsh weather, and hardware throughout is typically stainless steel or hot-dipped galvanized to resist corrosion.</p><p>The Jim-Buoy lineup is impressively broad. Horseshoe buoys and ring buoys come in a variety of sizes to meet different vessel requirements, while mooring buoys — including the well-regarded Mark V hard-shell series — feature virtually indestructible outer shells over high-density polyurethane foam cores. Channel marker buoys help navigators identify safe passages, and life floats are engineered to USCG-approved capacities for crews ranging from a handful of passengers to 22 or more. Even specialty items like winter stick buoys, designed in heavy-duty polyethylene to stay free in icy conditions, reflect the brand&apos;s thoughtful approach to real-world boating challenges.</p><p>Among the brand&apos;s most practical offerings are its <a href="/7281-cal-june-buoys-pickupmarkermast-buoys-202345">Pickup, Marker, and Mast Buoys</a> — versatile tools that let boaters mark anchors, hazards, fishing spots, dive locations, and race courses with confidence. Built from the same quality materials as the rest of the Jim-Buoy family, these buoys are straightforward, durable, and purpose-built for everyday use on the water.</p><p>Whether you&apos;re outfitting a personal watercraft, a commercial fishing vessel, a marina, or a community pool, Cal June&apos;s Jim-Buoy products deliver the dependability that safety-critical equipment demands. With a legacy built on consistent quality and a product range designed to cover virtually every buoyancy and marking need, it&apos;s easy to see why Jim-Buoy remains one of the most recognized names in marine safety.</p>

This Premium Mark V buoy features the toughest plastics available, with a rock-hard outer shell of nominal 1/8" thickness and a core of 2 lb. high-density polyurethane foam for exceptional durability and buoyancy. The white buoy includes a distinctive 2" blue band around the circumference for high visibility on the water.

Key Features:

  • Premium Mark V construction with ultra-durable plastic outer shell
  • Nominal 1/8" thick rock-hard exterior for impact resistance
  • 2 lb. high-density polyurethane foam core for superior buoyancy
  • 3" internal tube diameter for mooring chain attachment
  • White finish with 2" blue identification band
  • 24" diameter size suitable for medium to large vessels

Installation Guidelines:

  • Mooring chain should be 1/2" smaller in width than the tube inner diameter (recommended 2.5" chain for 3" tube)
  • Chain length should typically be 1.5 times the water depth at high tide
  • Total chain weight must not exceed 1/2 the buoyancy rating of the buoy

This mooring buoy is engineered to withstand harsh marine environments while providing consistent float and visibility for your mooring system.
