    D E H L E R 1.6. Anchoring, towing and mooring equipment 1.6.1. General The boat owner/skipper is responsible for ensuring that the mooring lines, towing lines, anchor chains and anchors are sufficient for the intended service area. Boat owner/operator should consider too which measures are necessary in order to use a tow-line on board.

  • Page 62: Towing

    D E H L E R 1.6.3. Towing The anchor line can be used for towing. However, a special towing line of the same strength is more suitable. Fasten the towing line in the shape of a bridle to the two bow cleats. In case of longer towing distances wind a rope of the same strength around the entire boat in order to distribute the towing forces.

    D E H L E R 1.11. Corrosion protection, painting system Only high quality materials were used. They are largely non-corrosive. The maritime climate is very aggressive. In result of this the forming of film of rust can appear, particularly in the vicinity of corrosive metal pieces. With suitable cleaning agent it is possible to remove the corrosion.

  • Page 73: Starting Up

    D E H L E R 2. Starting up 2.1.1. General notes Transport by water is more preferable than by land. If the boat shall be transported ashore, a special vehicle must be used, because the dimensions are too large for a transport by rail or a normal vehicle. Pay attention that the vehicle is suitable such transports.

  • Page 74: Underwater Painting

    D E H L E R Transport A land transport can only be carried out with a special-purpose vehicle. The guidelines for transport are generally the same as for slipping and storage, too. In addition, the yacht must be supported at forward and after quarters to relieve the structure. The yacht must be secured with at least 2 appropriate belts.

    D E H L E R Metallic parts may only be cleaned with metal polish. Please note that aluminium parts are anodised and must not be treated with scratching or polishing agents. Washdown the windlass and anchor chain regularly with fresh water. If the boat is not in use for a long period of time stand the cushions upright.

  • Page 81: Sails

    D E H L E R 4.3.2. Sails It is important to avoid luffing, fluttering or flogging, in order to conserve the strength and shape of the sails. Wear is a further problem. The first priority is to avoid any kind of chafing wherever possible. Where chafe is unavoidable it must be limited as much as possible.

  • Page 83: Winter Storage

    D E H L E R If the shaft rotates irregularly, it could be that some rollers have developed a flat side. This will have been caused by a temporarily blocking of the rollers by dirt parts. In most cases this will have been caused by dirt falling in from above on open tube systems.

  • Page 84: Rigging

    D E H L E R 4.8.2. Rigging Prior to winter storage, rinse the entire rigging and the sails with ample fresh water. The sails should not be dried in the wind in the mast (the flapping wear the sail and seams and there is a risk that cracks appear in the rigging).
