Whether you're fitting out a new vessel, upgrading your onboard water system, or troubleshooting an existing setup, you're in the right place. At Yacht-Mate Products, we've spent over 25 years solving water quality, air treatment, and waste management challenges for recreational boaters, sport fishermen, captains, and superyacht crew across Florida and beyond. Browse our most commonly asked questions below — and if you don't find what you're looking for, our team in Fort Lauderdale is ready to help.

WATERMAKERS & DESALINATION SYSTEMS

A marine watermaker — also called a desalination system or reverse osmosis unit — converts seawater into clean, drinkable fresh water onboard using high-pressure pumps and semi-permeable membranes. If you cruise offshore, anchor out regularly, or want independence from dock water, it’s one of the most valuable systems you can install. Yacht-Mate supplies and installs BlueWater and Tecnicomar units for vessels of all sizes.

Output depends on the model and vessel size. Compact recreational units typically produce 30–100 gallons per day. Yacht-class systems can produce 500–1,000+ gallons daily. Yacht-Mate will size the right unit based on your crew count, usage habits, and power setup. A TDS meter is recommended to verify water quality output.

Not always. Many compact units run on 12V or 24V DC, making them suitable for sailboats and solar-equipped vessels. Larger, higher-output systems typically require AC power via inverter or generator. Our team will advise on the right setup for your vessel’s power budget.

Entry-level portable units start around $1,500–$3,000. Mid-range installed systems for cruising boats range from $5,000–$12,000. High-capacity systems for motor yachts and superyachts can run $15,000–$30,000+, including installation. Contact Yacht-Mate for a quote tailored to your vessel and water production needs.

Simpler modular systems can be DIY-installed if you’re comfortable with marine plumbing and basic electrical. Complex framed or integrated systems — particularly on larger vessels — are best installed by a professional. Yacht-Mate installs and commissions all systems we supply throughout South Florida.

Flush the membranes after each use and whenever the unit sits unused for more than a few days. Replace pre-filters on schedule, and perform a full membrane cleaning based on run hours and water quality. Yacht-Mate stocks all replacement filters and membranes and our service team covers Fort Lauderdale and South Florida.

Yes. BlueWater’s Clear-Mate units are available in mobile configurations — ideal for vessels without a permanent installation or owners who move between boats. Ask our team about portable watermaker options.

A watermaker produces fresh water from seawater using reverse osmosis. A water filter purifies water that is already fresh — removing chlorine, sediment, and contaminants from dock or tank water. Most vessels benefit from both: a watermaker for offshore production and a filter system for final polishing at the tap.

WATER FILTRATION & DRINKING WATER

Dock water quality in South Florida and across the Caribbean can contain chlorine, sediment, heavy metals, and bacterial contamination. Fort Lauderdale’s waterways have documented water quality challenges — what comes through a marina hose isn’t always what you’d want in your tanks. A dockside filter stand or inline housing dramatically improves taste, odor, and safety before water enters your vessel.

A dockside filter connects directly to the marina hose before it enters your vessel. It removes sediment, chlorine, and contaminants as water passes through the filter cartridge. Yacht-Mate’s portable filter stands are popular with boats docked in Fort Lauderdale, Pompano Beach, the Bahamas, and the Caribbean.

Pre-filters should be replaced every 3–6 months depending on usage and water quality. Carbon and drinking water filters typically last 6–12 months. Yacht-Mate stocks a full range of replacement cartridges including 3M, Pentek/Pentair, and our own Yacht-Mate branded filters.

Replace your filter if you notice reduced water flow, an off taste or odor at the tap, or visible discoloration. If in doubt, err on the side of changing it — a blocked or exhausted filter offers no protection and can actually become a source of contamination.

Yes. We supply and install Viqua UV sterilizers, which use ultraviolet light to eliminate bacteria, viruses, and microorganisms from your onboard water supply. UV sterilization is the final barrier in a properly designed drinking water system and is strongly recommended for vessels filling from tropical or unknown water sources.

Silver ion technology provides ongoing antimicrobial protection in your water tanks and lines, inhibiting bacterial growth without chemicals. It’s a popular choice for cruising yachts and liveaboards who want sustained water quality between fill-ups.

It can be, but tank water carries risks that tap water doesn’t. Tanks can harbour bacteria, biofilm, and algae — particularly in warm climates like South Florida where heat accelerates microbial growth. Water sitting in tanks for extended periods is especially vulnerable. A properly designed system combining a sediment pre-filter, carbon filter, and UV sterilizer will make your onboard tank water safe to drink at the tap.

The best system depends on how and where you use your vessel. For boats on short coastal trips filling from marina connections, a quality dockside filter stand and an inline drinking water filter at the galley tap covers most needs. For offshore cruisers and liveaboards, a layered system — sediment filter, carbon filter, UV sterilizer, and a water softener if hard water is a factor — gives you full protection. Yacht-Mate can assess your specific setup and recommend the right combination of products.

WATER SOFTENERS

Hard water — high in calcium and magnesium — causes limescale buildup in watermaker membranes, boilers, water heaters, showers, and throughout your plumbing. A water softener protects all of those systems, extends equipment life, and gives you softer water for washing, laundry, and bathing. This matters particularly in Florida, the Caribbean, and the Mediterranean where water hardness is typically very high.

We offer portable single-tank softeners and installed single or twin-tank systems. Our range includes the Fill Fast heavy metal remover for additional protection. Whether you need a compact unit for a 35-foot cruiser or a full twin-tank system for a superyacht, we’ll specify the right solution.

Yes. Yacht-Mate water softeners are available in configurations suited to everything from recreational powerboats to 50-metre-plus superyachts. We assess your onboard space, water consumption, and plumbing layout to recommend and install the appropriate system.

Yes. Salt-based softeners require periodic regeneration using marine-grade salt. Frequency depends on water hardness and usage. Twin-tank systems allow continuous soft water supply while one tank regenerates — ideal for larger vessels with high daily demand.

MARINE ICE MACHINES

A marine flaked ice maker produces soft, fast-chilling flaked ice onboard — ideal for keeping fish, seafood, and provisions fresh, chilling beverages, or serving at the cockpit bar. Flake ice conforms to any shape and chills faster than cubed ice due to greater surface contact.

Flaked ice is the professional choice for sportfishing boats because it preserves catch quality better than cube ice — fish packed in flake ice stay at optimum temperature without bruising. On superyachts and charter vessels, it’s popular for food presentation, provisioning, and bar service.

The ICESEA is Yacht-Mate’s own-brand marine flaked ice machine, built specifically for onboard use. It’s engineered to operate reliably in salt air, handle vibration, and fit the space constraints typical of yacht installations. Available in multiple production capacities for different vessel sizes.

Yes. Yacht-Mate Products is based in Fort Lauderdale and supplies and installs ICESEA units throughout South Florida, including Miami, the Keys, Palm Beach, and the Treasure Coast. We also ship to customers across the US and internationally.

AIR PURIFICATION & ODOR CONTROL

Boat odors come from holding tanks, bilges, mold, diesel fumes, and stale air in confined spaces. Yacht-Mate supplies hydroxyl generator technology and GelAir products designed specifically for the marine environment. These don’t mask odors — they eliminate them at the molecular level.

A persistent musty smell after cleaning usually means mold or mildew is active inside the air conditioning ducts, headliner, upholstery, or in areas with poor airflow — not just on visible surfaces. In Florida’s heat and humidity, this is extremely common on vessels that sit closed at the dock between uses. An onboard air purification or odor control system running continuously is the most effective way to prevent it from returning.

Yes. Diesel odor is one of the most persistent complaints on motor yachts — particularly in engine rooms, bilges, and cabins on vessels that spend time at anchor or in enclosed marinas. Yacht-Mate’s hydroxyl generator systems neutralize diesel fumes at the molecular level rather than masking them. They run continuously and are safe with crew and guests onboard, making them far more effective than sprays or passive odor absorbers.

GelAir is a passive odor control product that uses a slow-release gel formula to continuously neutralize airborne odors in enclosed spaces — cabins, heads, bilges, and lockers. Unlike aerosol sprays, GelAir works 24/7 without power or maintenance, making it ideal for spaces where running an active system isn’t practical. It’s a popular onboard solution for keeping guest cabins and living areas fresh between voyages and during storage.

Boats left closed in warm climates — especially in South Florida’s heat and humidity — quickly develop stale, musty odors from trapped air, condensation, and mold spores multiplying in the dark. Running the air conditioning periodically helps, but the most effective solution is a continuous passive odor control product like GelAir placed in cabins, heads, and lockers while the vessel is unattended. For vessels left for longer periods, a hydroxyl generator running on a timer provides active odor and mold control throughout the interior without any risk to soft furnishings or surfaces.

WASTE TREATMENT

We supply marine waste treatment solutions including small package sewage treatment plants that meet environmental regulations for US inland waters and international cruising. Proper waste treatment is both a legal requirement and an environmental responsibility.

Yes. Florida has strict no-discharge zones across many waterways, and federal Clean Water Act regulations apply broadly. A certified marine sanitation device (MSD) is required on most vessels. Yacht-Mate can advise on compliant systems for your vessel type and cruising area.

A holding tank stores untreated sewage until it can be pumped out at a marina facility. A marine sewage treatment system (MSD Type II or III) treats waste onboard before discharge, allowing legal discharge in certain waters. For vessels that cruise actively or spend time in no-discharge zones, a treatment system offers far greater flexibility.

Fresh water tanks should be cleaned and sanitized at least once a season — and any time the vessel has been sitting unused for an extended period, particularly in Florida’s heat where bacterial growth accelerates rapidly. The standard method is flushing with a diluted bleach solution, letting it sit, then flushing thoroughly with clean water before refilling. Yacht-Mate stocks tank treatment and water freshener products that maintain water quality between cleanings and prevent bacteria and biofilm from taking hold in the first place.

No. Florida law prohibits the discharge of untreated sewage in state waters, and federal regulations under the Clean Water Act extend that prohibition within three miles of shore. In designated No Discharge Zones — including the Florida Keys — even treated sewage cannot be discharged overboard. All waste must be stored in a holding tank and pumped out at an approved marina facility. Yacht-Mate can advise on compliant marine sanitation systems for your vessel.
