Sticking with the same home insurance could cost you

Home insurance costs are rising fast, up nearly 40% nationwide in just the past few years. With premiums changing constantly, sticking with the same provider could mean overpaying by hundreds of dollars. Shopping around and comparing multiple insurers can help lock in better rates without losing the protection your home needs.

Oahu Neighborhoods

Marina views, vaulted dreams, and adventure at your doorstep

Mariners Cove emerged in 1968 as part of industrialist Henry J. Kaiser's master-planned Hawaiʻi Kai development. The first home was built at the entrance to the peninsula at 7079 Niumalu Loop on the corner of Kamilo Street. The neighborhood was designed to maximize marina visibility and water access, with strategic placement of mini parks where cross streets meet the waterfront. The signature architectural style—featuring tall vaulted ceilings with exposed rough-cut lumber planks—reflects the Hawaiiana design trends of the late 1960s and early 1970s. Many homes have been thoughtfully modernized and expanded while preserving the original floorplans and distinctive character.

Explore Island Design

Vaulted ceilings and island soul built into every beam

Mariners Cove was born in 1968, and you can still see Henry J. Kaiser's vision in every home. The signature style? Tall vaulted open-beam ceilings with exposed rough-cut lumber planks that add warmth and volume to living spaces. Walk through the neighborhood and you'll spot board-and-batten exteriors, lava rock accent walls, and those distinctive architectural lines that defined Hawaiiana design in the late '60s and early '70s.

Typical homes range from 1,459 to 3,000 square feet on level 7,500 to 9,600 square foot lots—generous by today's standards [1]. Many have been thoughtfully modernized with open-concept kitchens, updated baths, and expanded living areas while preserving those iconic vaulted ceilings that make the space feel twice its size.

Vibrant Lifestyle

Private club access, waterfront parks, and 72 reasons to stay local

Life in Mariners Cove revolves around water. All residents enjoy exclusive use of the Mariners Cove Bay Club at 800 Lunalilo Home Road—a 121-person capacity clubhouse complete with a lap pool, kiddie pool, boat launch ramp, and a 25-boat storage yard. Boat stalls are available for rent, making it easy to keep your watercraft ready for weekend adventures.

Beyond the marina, the neighborhood boasts strategically placed mini-parks along the waterfront at Opoi Street, Paoo Street, and Koamano Street—thoughtful green spaces that maximize open views and create natural gathering spots. Koko Marina Center, just minutes away, offers 72+ merchants including Kona Brewing Co., Heavenly Island Lifestyle, Moena Café, and essentials like Walgreens and Petco—all with convenient parking and marina-side ambiance.

Adventure seekers can tackle the Koko Crater Trail's 1,048 railroad-tie steps for sunrise views over Hanauma Bay, snorkel with sea turtles at the world-famous nature preserve, or catch bodyboarding waves at Sandy Beach—all within a 10-minute drive.

Real Estate in Hawaii Kai

$1.65M median, marina-front premiums, and what buyers need to know

Marina-front properties—representing just 94 of the 410 total homes (23%)—command premium pricing, often reaching $2 million or more depending on location and upgrades. Homes along Kalanipuu Street, particularly those facing the bird island with wide frontage and extensive marina depth, are especially coveted.

For Hawaii Kai Marina overall, the median home price in July 2025 was $1.4 million, up 11.5% year-over-year, with an average of 70 days on market compared to 39 days the previous year. Buyers benefit from increased inventory and longer decision windows, while sellers should price strategically and prepare for extended timelines. Interior homes (non-marina-front) typically sell in the $1.4-$1.6M range, offering strong value for families prioritizing space, schools, and Bay Club amenities over direct water frontage.
