Before using Propspeed, we had as much as 4 inches of growth on the propeller shaft. With Propspeed applied, our running gear is now free of growth.
Yankee Freedom III
Yankee Freedom III operates 7 days a week carrying passengers to the Dry Tortugas National Park, 70 miles from Key West, Florida, USA.
Made up of seven small islands, the Dry Tortugas National Park is one of the world’s most unique eco-attractions. Its crown jewel, the historic Fort Jefferson, was once used as a prison during the Civil War, and has now become a tourism highlight of Florida, with diving and nature exploration opportunities abound.
As the name would suggest, Yankee Freedom III is the third vessel in the fleet, having replaced Yankee Freedom II in 2012.
The ferry covers a distance of 150 miles every day, 7 days per week with a working speed of 29 knots, and capacity for 175 passengers.
Prior to using Propspeed, the boat was having significant growth on the shaft of its props, causing severe strain on the engine.
When a diver was sent down to inspect the prop and shaft, he noticed that there was as much as 4 inches of grey moss growth running along the shaft.
Yankee Freedom’s captain, Rick knew there was a solution out there, having heard rave reviews of Propspeed from boat owners around Florida and the Carribean.
The tenacious adherence of Propspeeds etch, combined with the environmental benefits of using a foul-release system, rather than traditional antifoul made Propspeeds biocide-free system the obvious choice to stop marine growth on their vessel.
Yankee freedom promptly had Propspeed applied to the vessels Props and shafts at their next haul, and have made sure it’s on the job list at each annual haul.
Since then, the Yankee Freedom fleet haven’t had any growth issues on the vessels running gear between their annual haul-outs, with a fresh Propspeed application being part of their specified service at each haul-out.
What is the shelf life of Propspeed
All Propspeed kits have a shelf life of 3 years from date of manufacture.
The date of manufacture should be clearly labelled on your kit and components
What parts on the bottom of the boat can be coated with Propspeed?
Propspeed can be applied to any metal part below the waterline, including propellers, shafts, struts, rudders, trim tabs and through hull fittings. You can also use the clear coat directly on plastic bow-thrusters and underwater lights.
Is Propspeed expensive?
Propspeed may cost more to buy than conventional anti-fouling paints, but the feedback we get constantly from boat-owners is that it pays for itself. By keeping the running gear free of marine growth, not only does it reduce the time spent cleaning at next haul-out, but it reduces your running costs by increasing your speed and reducing your fuel consumption
What sort of maintenance does Propspeed need?
None. The foul release formulation is self-cleaning as soon as the propeller starts up. If required, a light wipe with a non-abrasive cloth will remove any marine growth. When hauling out, ensure the Propspeed is wiped down with a non-abrasive cloth before any marine growth on the surface can dry. Water-blasting, scraping and other abrasive cleaning will damage the Propspeed and eliminate its effectiveness.
Will Propspeed affect the life of my sacrificial anodes?
The application of Propspeed greatly reduces the wetted metal surface and the positive outcome is that our customers are seeing an increase of vessel speed with less RPMs, fuel savings and, the protection from stray current damage resulting in longer sacrificial anode life. It has been observed by our customers that by using Propspeed on their running gear and propellers they have seen a dramatic reduction in corrosion to their underwater metals and that their sacrificial anodes are lasting longer..
How long after application of Propspeed until I can launch my boat?
A minimum of eight hours drying time is required after the final coat. This is based on an average air temperature of 15 deg C, or 59 deg F. If the air temperature is colder than this, a minimum of 24 hour curing time is recommended.
How does Propspeed work?
Propspeed is a foul release coating, not an anti-foul, so it doesn’t harm marine life. The top coat on the Propspeed system is an ultra-slick surface that marine growth can’t grip. Propspeed’s effectiveness does depend on movement of your boat - the more you use it, the better Propspeed performs. Propspeed sets itself apart from the competition with the exceptionally strong chemical and physical bond between the metal substrate, the primer and the top coat - this ensures that the Propspeed coating actually stays on your running gear.
Is Propspeed environmentally friendly?
Yes. Propspeed contains no copper, tin or any other toxic substances harmful to marine life.
How long does Propspeed last?
Propspeed will last at least a year, but many customers report another one or even two years service life. This depends on what sort of marine environment your boat is moored in, the water temperature, and how often you use it.
Will Propspeed lose its effectiveness if my boat is out on the water for a period of time?
No, provided the only maintenance given to the parts with Propspeed applied is a light wiping with a non-abrasive cloth, the boat can be hauled and launched multiple times, or left out for long periods without affecting the performance of Propspeed. If you are having the bottom of the boat high pressure washed ensure that any Propspeed coated parts are covered to prevent damage.
Can Propspeed protect against Zebra mussels and other freshwater growth?
Propspeed can be used successfully in fresh or salt water. As it’s a foul release, not a biocide or anti-foul, Propspeed relies on a slick surface - it doesn’t matter what sort of marine growth you have, it won’t be able to get a grip.
Can I apply Propspeed myself?
For best results we recommend Propspeed is applied by a trained applicator. See our applicator finder, or or your haul-out facility may already have an arrangement with an applicator.
