Blount installs Delta 'T' ventilation system on new ferry


(RIVIERA BEACH, Fla., and WARREN, R.I.) — Governors 1, Blount Boats' newly launched 400-passenger ferry, provides service between Lower Manhattan and Governors Island, a park-like respite 0.5 nm away from the bustle of New York City. Specified by naval architecture and marine engineering services firm Glosten Inc., the shipbuilder installed a high-performance engineered ventilation system from Delta "T" Systems.

The 132-by-40-foot Governors 1 has dual 800-hp engines, so maintaining optimal air pressure and temperature is critical for peak performance and efficiency. Adequate airflow is also essential for crew comfort and safety. Delta "T" engineered the system with two 5 hp intake and two 2 hp exhaust fans controlled by its 600-C2 manual control. Humidity is managed with a pair of aluminum moisture eliminators.

Governors 1 is built to U.S. Coast Guard Subchapter K standards, so four Delta "T" Slimline A60-rated fire dampers were installed, the thinnest damper on the market at only 4.25 inches deep. One hundred percent 316 stainless steel, it's Coast Guard-approved for use in penetrating Class A-0, A-15, A-30 and A-60 bulkheads and decks, and is also Wheelmark certified under EU Marine Equipment Directive (MED).

"We've been installing Delta 'T' Systems products for 20 years," said Bob Pelletier, Blount Boats vice president. "The engine room ventilation system installed on Governors 1 has had excellent performance."

Since 1949, family owned Blount Boats has designed, built and repaired steel and aluminum commercial vessels. The six-acre Warren, R.I., shipyard has the capacity to build boats up to 220 feet. Its website is
