Vico Marine Boat Cover Venting System with Boat Vent 2 – 28″ to 47″

The Premium Support Pole is built from heat-treated, anodized aluminum with a ribbed profile for strength and lightweight durability. It can hold up to 170 lbs, roughly double the capacity of standard poles. The CAM LOCK design uses a patented flip-lock mechanism to adjust height from 28″ to 47″. This lets you set the exact tension to maintain your cover’s shape and protective tenting. The Boat Vent 2 is included to improve airflow beneath the cover, reducing humidity and heat buildup inside the boat.
Best for: boaters needing a compact, robust pole with strong load tolerance and a straightforward adjustment system for smaller-to-mid-sized boats. This setup is ideal when quick height changes are needed to adapt to deck angles and cover tension. Limitations: the 28″ to 47″ range may require a longer option for very tall vessels or deep hull profiles.
Vico Marine Boat Cover Venting System with Boat Vent 2 – 23″ to 55″

This version features a robust heavy-duty pole made from anodized aluminum with two patented flip-locks for maximum adjustability. The spline tip locks securely into the Boat Vent 2, and the swivel pole base uses thermoplastic rubber to provide a firm, non-marring grip that won’t scuff boat floors. It delivers consistent airflow, reduces condensation, and helps protect against water damage during storage.
Best for: owners who want adjustable venting with dual-lock security and a floor-friendly base. Choose this if you store multiple boat sizes and value a base that stays in place on various deck textures. Caution: ensure the base height aligns with your cover’s clearance to avoid contact with hardware on the hull.
Vico Marine Boat Cover Venting System with Boat Vent 2 – 39″ to 70″

The 39″ to 70″ CAM LOCK system provides strong tension to maintain a tented cover over larger boats. The pole is heat-treated, anodized aluminum rated to hold up to 170 lbs, and includes a spline tip that locks into the Boat Vent 2. It also includes a vented cover solution to minimize humidity and heat buildup beneath the cover.
Best for: larger boats that require higher support and a secure tenting solution. Better for: windy storage conditions where extra pole height and tension help prevent water pooling. Limitation: taller setups may require a longer deck clearance to avoid interference with rails or antennas.
Vico Marine Boat Vent II

Boat Vent II is a quick and easy installation venting solution designed to reduce moisture buildup and maintain airflow under covers. It’s compatible with custom and semi-custom covers and supports poles sold separately. The vent is built to withstand harsh sun, saltwater, and extreme weather, providing improved ventilation and protection against water pooling when used with a compatible pole system.
Best for: buyers seeking a straightforward venting accessory that can be retrofitted to existing covers. Choose this to simplify airflow management without committing to a full pole system. Limitation: vent-only solutions may require a separate pole system for complete tenting support.
Vico Marine Boat Cover Venting System with Boat Vent 3 – 23″ to 55″

Boat Vent 3 uses an adjustable aluminum support pole with a 23″ to 55″ range and two flip-locks for fast, secure height changes. The pole holds up to 170 lbs and the swivel base adapts to deck angles to protect flooring and provide stable setup. It emphasizes winterization and moisture control by promoting consistent airflow and reducing humidity inside the cover enclosure.
Best for: those who want a versatile, high-capacity system for mid to large boats, including seasonal storage in variable climates. Better for: owners needing a pivoting base to match uneven deck angles. Limitation: taller or heavier boats may benefit from additional pole support or a heavier-duty base for extra stability.
Buying Guide
What purchase considerations matter?
- Boat size and hull depth: Choose a pole range that covers your boat height without overextending the pole.
- Ventilation needs: A Boat Vent II or Boat Vent 3 helps manage humidity; combine with a vented cover for best airflow.
- Pole material and durability: Anodized aluminum offers high strength and corrosion resistance for saltwater environments.
- Lock mechanism: CAM LOCK or flip-lock designs provide quick, secure height adjustments and tension control.
- Base type and floor protection: Swivel bases with non-marring grips protect decks and enable alignment with deck contours.
- Installation effort: Some systems require minimal tools and provide straightforward assembly, while others may demand more setup time but offer greater customization.
How to compare options quickly?
- Height range versus boat size: Ensure the range accommodates both tenting and tall masts or antennas.
- Weight rating: Higher weight ratings indicate stronger poles that resist wind and snow loads.
- Vent integration: Vents should promote airflow beneath the cover without letting rain intrusion through the fabric.
- Base compatibility: Check deck material and contours to avoid scuffs or instability.
What questions should you ask before buying?
- Is the pole range sufficient for my boat height and cover depth?
- Does the system include a Boat Vent or is it compatible with an existing vent?
- Are replacement parts available if a component wears over time?
- Will the base protect my boat deck from scuffs while withstanding wind?
Practical setup tips
- Mount the Boat Vent first, then attach the pole for precise tensioning.
- Test the pivoting base on dry surfaces to prevent slipping once moisture is present.
- Periodically inspect the spline tips and flip-locks for secure engagement.
- When storing for winter, check that the vented airflow remains unobstructed by accessories or covers.
FAQ
- What is the benefit of a vent pole system? It improves airflow under the cover, reducing heat buildup and moisture that can cause mold or mildew.
- Can I retrofit a Boat Vent II with any pole? Yes, most poles designed for Boat Vent II are compatible with the vent’s locking mechanism and provide secure attachment.
- What height should I choose for a tall boat? Choose the tallest setting that still allows the cover to tent properly over the hull without rubbing rails or antennas.
- Are these poles waterproof? The materials are designed to resist water and corrosion in marine environments, but regular maintenance helps extend life.
- Will a swivel base damage my deck? A high-quality swivel base with a non-marring grip minimizes risk to deck surfaces when mounted correctly.
- Do these systems require professional installation? Most setups are designed for DIY installation with basic hand tools.
