“Vast ocean crossings have put The Big Blue's machinery and construction to the test, and we are happy to say she handled the seas and distances without falter.”
Captain, The Big Blue
From the photos below, you can see that the Propspeed foul-release coating on The Big Blue’s propeller is looking a little worn. According to chief engineer Andrew Dias, at the time, The Big Blue had just traveled 32,000 nautical miles on a single application done more than two years ago, so the wear is quite understandable!
From her very first launch, The Big Blue has always had Propspeed on her running gear, applied by Marine Group Boatworks in Chula Vista, California. While this unfortunately ruled out the possibility of “before” and “after” fuel-savings comparisons, the 138-foot 2009 expedition megayacht continues to travel long distances; a recent 10-month voyage from Florida to Southeast Asia and throughout the South Pacific logged 22,000 nautical miles. With an average cruising speed of 11 knots, the savings and performance benefits were significant—particularly with the added load of a helicopter on her helipad.
“Vast ocean crossings have put The Big Blue’s machinery and construction to the test, and we are happy to say she handled the seas and distances without falter,” says captain Gareth Sheppard.
Refitted by Derecktor Florida in 2013 to include the helipad, The Big Blue was nominated for best refitted yacht at the 2014 World Superyacht Awards. After a complete repaint in 2015, she underwent extensive maintenance and upgrades at Rybovich Shipyard from 2016 to 2017 and had both of her generators completely overhauled in 2018. Now located in West Palm Beach, she is up for sale and promises to be a pleasant surprise for her new owner, “surpassing all expectations by way of comfort, cruising range, fuel economy, stability and all-round functionality.”
What size Propspeed kit do I need?
The right kit for your needs will depend on the size of the area you’re coating. Our three kit sizes correspond to the following coverage areas:
200ml: up to 0.4m2 or 4.3ft2
500ml: up to 1m2 or 10.75ft2
1 liter: up to 2m2 or 21.5ft2
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.
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.
