Marina WiFi: 7 things to look for before you sign a contract

Marina WiFi is a genuinely specialist area. The environment is hostile to standard WiFi equipment, salt air, metallic hulls, dispersed pontoons and water all create challenges that generic IT suppliers regularly underestimate. Signing the wrong contract can cost you years of frustrated berth-holders and expensive re-installation work.

Before you commit to any supplier, here are seven things worth investigating carefully.

1. Have they actually done marinas before?

The single most important question. Marina WiFi is not the same as office WiFi or even holiday park WiFi. The propagation characteristics of signals over water are different. Salt-laden air corrodes untreated equipment quickly. Hulls absorb and reflect signals unpredictably.

Ask for specific marina references, not just "outdoor installations." Ask to speak with a marina manager they've installed for. If they can't provide this, they may be learning on your site.

2. Is the hardware rated for a marine environment?

IP67 or IP68 weatherproofing, stainless steel fixings, corrosion-resistant coatings, these aren't optional extras for a marina installation. Standard outdoor access points rated to IP65 will corrode faster than you'd expect in a high-salt coastal environment.

Ask specifically about the IP rating of access points being proposed, the material of fixing brackets, and the cable gland specification. A supplier who doesn't understand why this question matters hasn't done enough marinas.

3. How do they handle signal penetration through hulls?

GRP fibreglass, steel, aluminium, every hull type absorbs WiFi differently. A steel-hulled narrowboat in an inland marina is a different challenge to a fibreglass sailing yacht in a coastal marina.

Good marina WiFi requires a site survey that accounts for the actual berth-holder mix, the angle of AP placement relative to pontoon orientation, and likely upgrade paths as the fleet changes. Ask how the design accounts for hull types.

4. What's the pontoon cabling plan?

Running cable along pontoons that flex, flood occasionally and need to be removed for maintenance is a real engineering challenge. How are cables protected? What happens when a pontoon section needs servicing? Is the cabling sealed against water ingress?

These aren't nit-picks, they're questions that determine whether the system keeps working 3 years later without major remedial work.

5. What's the contract term, and who owns the equipment?

Some marina WiFi suppliers offer "free installation" with a long managed service contract, similar to the holiday park model. Others charge installation cost upfront. Both are legitimate, but you need to understand:

• Who owns the access points and switching equipment?
• What happens at the end of the contract term?
• Can you exit early, and at what cost?
• What are your rights if the supplier ceases trading?

Equipment ownership matters particularly in marinas because access points are fixed to your pontoon infrastructure, removing them or replacing them mid-contract can be disruptive and expensive.

6. What does the managed service actually include?

Terms like "proactive monitoring" and "managed service" mean different things to different suppliers. Clarify:

• Is there remote monitoring with automated alerts?
• What's the response time for a reported outage?
• Are on-site visits included in the monthly fee, or billed separately?
• How are firmware updates and security patches handled?
• What's the hardware replacement policy if an AP fails?

7. Can the system scale as the marina grows?

Marinas expand, new pontoons, additional berths, a new chandlery or boatyard. A good WiFi system should be able to grow with you without requiring full replacement. Ask about the maximum capacity of the network controller, the cabling architecture, and the upgrade path.

Systems built on enterprise platforms (Ubiquiti, Ruckus, Cisco) are generally much more scalable than proprietary systems from smaller suppliers.
