Archive for the ‘AntiFouling’ Category
A process we regularly undertake is the waterproofing and antifouling of trailer boats so they can live in the water without any issues. The common idiom is that black antifoul is the best thing however it is proven that this can devalue the vessel and is very difficult to remove. We use a special white antifoul coating and couple it with one of our own CleanABoat.com Ultrasonic Antifouling systems which provides the ultimate long term Antifouling protection. This job was on a 18 foot Stingray. First we found the appropriate water line by putting the vessel in the water and carefully measuring around the hull. Then the hull was prepared and waterproofed with a special sealing epoxy coating, primed and then anti fouled with a special hard white antifoul coating, finally a CleanABoat Ultrasonic Antifouling system was installed which coupled with the hard white antifoul will keep the hull clean of growth for 2-3 years before a simple hull scrub and touchup is required.
The new owner of this Regal arrived for a Antifoul and Popspeed however upon lift there was some bad previous antifoul applications that had caused the antifoul to begin to flake off. Simple application to this surface of the new antifoul coating would not be ideal as it, much like the previous coatings, would tend to flake off. What was needed was a removal of all previous antifoul coatings and a start from the beginning process of sealing, priming and antifouling. This process provides the ultimate hull antifoul protection and repairs the issues left from previous poorly applied/prepared coatings. You will see throughout the images below the poor surface with flaking antifoul and some progress images throughout the repair. We also applied Prop speed to both props and serviced the engines and stern drives.
Prior to Sandblasting you can see the flaking antifoul.
Another Happy customer leaving. Happy with his like new vessel
65′ foot Aluminium Twin Hull Super Powered Catamaran Repairs, Respray/repaint and Antifoul.
The CleanABoat Services team has been busy with this project at the Gold Coast City Marina in Coomera on the Gold Coast. Underway is a complete exterior respray/repaint and anti-foul all performed to a budget. Major repairs are also being undertaken to the exterior and some “redesign” of the paint scheme along with a new area of non skid decking to increase the pleasure and useability of the vessel. The completed cat will include a complete respray with JOTUN Marine 2 Pac Urethane white and black. The non skid is to be altex/resene non skid coating.The hull will be coated with JOTUN advanced antifoul products after a thorough clean. Along side CleanABoat’s team there has also been a major interior refit underway to reface this vessel to be a majestic 21st century vessel.
Expected completion to be mid December this year (2010) ready for Christmas when we are sure it will have plenty of use! We might even join the owner for a brewski or three! Check out the gallery below and we will continue to update as we go!
35′ Riviera Flybridge Cruiser Osmosis Repairs, Gold Coast Marine Centre
This vessel is an older 1989 35 foot Riviera Flybridge vessel, recently purchased from Sydney the vessel was turned back to shore shortly after beginning its trip to the Gold Coast for our repairs, taking on water with a failed prop shaft seal the vessel was lifted and placed on a truck to deliver to our possession at the Gold Coast Marine Center in Coomera for her repairs.
Repair short list:-
- Failed prop shaft seals, both port and starboard
- Ceased prop shaft couplings
- New prop shafts required
- Numerous Spot Osmosis issues
- Re-Antifouling required
- Prop Speed props
- Full Machine Buff and polish
- New anode mounting on transom + new anodes all round
- New Transducer sender mounted on port side hull
- New boot stripe
We started this job by removing the old antifoul by sand blasting the hull, this allowed us to get a better visual on the osmosis issues and begin repairs. Once repaired the hull was coated with with 4 coats of JOTUN JOTACOTE 605 (2 part epoxy sealer), then 2 coats of JOTUN VINYGARD 88 (vinylester epoxy primer) and finally 3 coats of JOTUN SEA GAURDIAN black antifoul. We work closely with the technical representatives of the product systems we use to ensure the best and longest lasting final finish. During this process a new Transducer sender was installed on the port side hull and a new mounting position for a larger new anode was installed on the transom as the existing anode system was lacking. Two new prop shafts, prop shaft couplings & prop shaft seals where installed along with new ruder gland seals. The props where x-rayed and coated with prop speed before being put back together. Once this was completed we applied a new boot stripe and gave the entire vessel a complete buff and polish with cleanaboat.com products.
During sea trials we noticed a large performance improvement with ~3 knot top speed improvement and improved performance through the range. Better economy also was noticed.
