Seldén provides three types of swivel they are the deck swivel, the mast swivel and eye swivel.
Type EYE SWIVEL
The eye swivel is designed for control lines close to the deck, as with dinghy jib sheets. The swivel can also be used on bigger boats if the purchase of the tackle is sufficient. One eye swivel on each side of the coach roof is an ideal set-up for the vang. The crew on the rail can easily reach the vang to prevent a broach. The angle of articulation is easily adjusted with two screws. The swivel turns on stainless steel ball bearings for durability. The eye swivel is made of glass fibre filled polyamide with an electro polished, stainless steel line guide.
Type DECK SWIVEL
The deck swivel articulates to follow the movements of the trimmer. Used for main sheets on keelboats and smaller yachts. Can also be used on bigger boats if the purchase of the tackle is sufficient. The materials used are composite and stainless steel.
Type MAST SWIVEL
The mast swivel leads the line with full articulation towards the trimmer. The swivel is made of glass fibre reinforced composite. It is mainly used for Cunningham, Spinnaker and Gnav etc. The sheave has two optional positions, either for lines coming from above or from below. The mast swivel can be fitted “up-side-down” depending on desired orientation of the cam cleat. The sheave is of ball bearing type.
