NOA A-Frames for boats without pulpit and pushpit

NOA A-frames are specially designed for sailboats and motor boats where no pulpit, pushpit, or surrounding rail system is available for mounting a traditional deck frame system. In addition, many of these boats do not have a surrounding deck or gunwale where conventional deck supports could brace against.

Smaller motor boats, open boats, fishing boats, long rowing boats, trailer boats, and compact sailboats especially benefit from this flexible solution for winter covers and protective tarpaulins. The telescopic A-legs are positioned on the ground at the bow and stern of the boat and carry the main load of the frame construction. This helps prevent wind and snow loads from being transferred directly onto the boat. Additional deck supports brace against the deck, gunwale, cabin roof, or cockpit and provide extra stability.

Thanks to the telescopic design, the height, width, and roof angle can easily be adjusted to different boat shapes and deck layouts. This allows rainwater and snow to drain more effectively while maintaining good airflow and ventilation underneath the cover.

For the best fit, the frame should generally be selected slightly longer than the boat itself. The ridge tubes are connected using NOA’s strong tube connectors. The T-connectors used in the NOA frame systems are significantly stronger than many standard tube fittings found in simpler systems.

The NOA fittings and brackets use plastic sleeves to provide excellent grip while also helping prevent galvanic corrosion between aluminum and stainless steel.

All aluminum components are carefully finished and deburred by NOA to eliminate sharp edges that could damage the cover. The frame systems are designed to withstand high loads and strong winds. NOA has more than 30 years of experience in the development and production of aluminum frame systems and boat covers.
