Smooth Sailing Boat Bottom Paint is a low drag, non-stick bottom coating which uses copper to keep growths away. Also available is Teflon only clear, or non copper, hard long lasting Urethane Teflon in White, charcoal, navy and red. For a free boat bottom paint cost analysis including step by step instructions and a profile of everything needed to do a professional job go to http://www.boat-bottom-paint.com:80/costanalysis.aspx This copper coating relies first on the large polytetrafluoroethylene (PTFE) well known for its use in non-stick cookware. This molecule produces a drag coefficient smoother than ice. Also uses is copper. Smooth Sailing copper will change color over time when immersed. The true color will establish itself after the boat has been launched. Often the color will turn from copper to a dark gray tone. Because color change will occur over time, you should try to keep the Smooth Sailing Antifouling coating as close to the true waterline as possible. Wet sand and apply with roller and brush. One to two quarts covers most boat bottoms. Call 800-466-8910 www.boat-bottom-paint.com for more details. Growth on boat bottoms is perhaps the major factor in reducing speeds and increasing the energy required moving through the water. If you want a slippery boat which produces the most speed with the least energy you need to focus on the part of your boat that creates resistance to the water it passes through. A great hydrodynamic shape and maximum water line length are all critical. But once the boat is designed and built what you can add to the mix is a smooth, low drag bottom. That smooth bottom means keeping the ravages of nature away from your boat bottom. To date the best tools you have for maintaining a smooth boat bottom is to keep the boat out of the water. But for those of us that can’t remove the boat when in use, we need to provide our boat bottom with the smoothest coating available. And we need to discourage organic growths by using materials like copper to discourage colonization on our boat bottom. Growth on your the bottom of you boat can reduce its efficiency by as much as 10% and that growth can be released from a properly coated bottom when speeds of 10 to 15 knots are reached. Once fouling has established a hold on a boat hull it will rapidly spread or "colonize" the surface. Prevention is therefore better than the cure of having to remove the fouling by scraping. If you can keep growths off of your boat bottom you can. Use less fuel
Other reasons to keep your bottom free from fouling Protection Speed and Efficiency Antifouling boat bottom coatings are not meant to be a cosmetic or decorative coating. While no boat bottom paint can always keep growths away a non-stick Teflon type surface helps dramatically. Smooth Sailing boat bottom coatings rely first on the large polytetrafluoroethylene PTFE molecule which produces a drag coefficient smoother than ice. As water flow is increased over the boat bottom with speed most growths will slip off the boat bottom, but just like eggs in a pan a little help does not hurt. You may want to brush, pressure wash or wipe your bottom periodically. Copper is used for Antifouling in one of our coatings and has been protecting boat bottoms from growth since the 1700’s when Britains Fast Ships like the Cutty Sark raced from the orient to England with cargo’s of fresh Tea. Most marine life does not like the taste of copper and will try to avoid it. Because your boat bottom is so important to the boat performance the bottom should be re-coated as often as possible. Smooth Sailing’s Antifouling coatings will retain their Antifouling properties as long as the coating is on the hull even if stored dry. Sanding between coats will add to the longevity of the bottom jobs. By sanding the bottom you can get more coats to adhere and forestall the day when too many coats means that you must remove all the Antifouling coatings from the surface and start over. The boat bottom should always be sanded before an additional coat even if they have just been power washed. Antifouling performance factors While tin and other biocides have been used on boat bottoms over the years. The proven standards still relates to the level of copper used. Yet Copper is not the only determining factor of how well an Antifouling paint will perform. The resin-binder system, the material that holds the paint together, is equally important. In addition to holding the paint together, the resin-binder system determines how fast the copper and other biocides are released. The resin-binder system should be carefully tailored for the amount and type of copper used to obtain maximum efficiency. The amount of copper affects the life of an Antifouling coating but the sophistication of the resin-binder system to hold and release copper is far more important to the effectiveness of the Antifouling effect. The best Antifouling boat bottoms will release biocide at a nearly constant rate throughout its life. If the resin-binder is correct, the highly efficient copper biocide is less dependent on large amounts of copper to deliver the best possible performance. Why use Fluorourethane on your boat bottom? Fluorourethane was originated by the U.S. Naval Research Laboratories (NRL) in the early 1970.s. It was a combination of a fluorocarbon (Teflon) molecule with a urethane molecule. The material was unique in that it provided a surface with approximately the same coefficient of friction as the Teflon, was hydrophobic, UV resistant, and at the same time provided an abrasion resistance four times that of Teflon. The fluorourethane was originally tested on several ship hulls for the U.S. Navy. One boat tested was a harbor tugboat in Chesapeake Bay. The coating lasted 11-1/2 years compared to a conventional hull coating which lasted only 18-24 months. Of major interest was the fact that no rust or corrosion occurred under the coating. And biofouling, such as barnacles, could be removed with a high-pressure water jet instead of chipping or shot blasting. # |

BMW 4-Series Gran Coupe revealed – looking very like the 3-Series Saloon
Sat, 01 Feb 2014The first photos of the new BMW 4-Series Gran Coupe arrive The BMW 6-Series Gran Coupe looks like a four-door stretched version of the 6-Series, as it should, And it works; it’s a simply brilliant car. But we always wondered how BMW were going to differentiate the 4-Series Gran Coupe from the already existing 3-Series, which is already a 4-door saloon version of the new 4-Series Coupe. And if the leaked photos of the new 4-Series Gran Coupe are anything to go by, the answer is – not by a lot.
Porsche 918 Spyder takes on the Nurburgring
Fri, 21 Sep 2012Porsche has taken their concept hybrid supercar – the 918 Spyder – to the Nurburgring to set a time – 7 minutes 14 seconds. But a hybrid halo doesn’t have to mean poor performance, a point Porsche has proved by taking the 918 Spyder to the Nurburgring to set a lap time. The Porsche 918 Spyder can deliver a total of 759bhp from its race-derived V8 and two electric motors which, although less than the likely power available to the F70 of P1, is still a significant amount of get up and go.
