How It Works
Specifications
Are you looking to replace toxic antifouling with a frequent hull cleaning program? Then there are three things you need to investigate.
Sailboats
1. Keel and Rudder Length
The keel length must not exceed 2,3 meters from the waterline to the bottom of the keel. The length of the keel itself must not exceed 1,6 meters (from the bottom of the hull to the bottom of the keel).
The same goes for the rudder; the length must not exceed 1,6 meters. If the rudder is longer than 1,6 meters, you must notify the operator and the brushes will be stopped before they get close to the rudder. The machine cannot clean sailboats with twin rudders.
2. Keel width
The keel width must at no point exceed 45 cm. That goes for the bulb width which normally is the widest part, but also the width of keel where the keel meets the hull. This means that older sailboats with a wide keel cannot be cleaned.
3. Bulb types
The machine can only clean sailboats with a straight keel, or bulbs/oval shapes no wider than 45 cm. The machine does not clean other bulb formations such as winged keel or flat keeled bulbs.
Motorboats
Outboard engines
Motorboats with an outboard engine has a hull that can be cleaned completely in the machine. The same goes for all types of motorboats where the propulsion/propeller sticks out in the stern such as water jets, surface drives and stern drives that can be tiltet up. On the stern, a hand held pressure washer can be used to remove fouling when accessible. The before and after renders below indicates which part of the hull that the machine is able to access and clean. As there are many hull types and individual differences, results may vary.
Inboard engines
Motorboats with a centered shaft and propellers no wider than 30 cm in diameter have hulls that can be cleaned completely in the machine. If the propellers are larger than 30 cm in diameter, the hull can be cleaned up until the point where the shaft exits the hull.
Boats with double shafts or pod drive have a hulls that can be cleaned up until the point where the shaft exits the hull. The same goes for the pod drive.
Frequently Asked Questions
How effective is the method?
Â
For the best results throughout the boating season, we recommend regular use so that the marine fouling never has time to become a real fouling hazard. If you don’t manage to clean your boat regularly, it’s no disaster. Our cleaners can remove even thick fouling such as adult barnacles and other resistant fouling!
How often should I clean the hull?
Â
To optimize boat performance, hull cleaning is desirable as soon as fouling accrues, normally every 4-12 weeks. Factors that impact on cleaning frequency include:
Â
- Â Geographical location
- Â Regional variations
- Â Water temperature
- Â Water salinity
- Â Frequency and duration of boat usage
- Â Boat speed
For best results regular cleaning is recommended. This will prevent marine fouling building up.
