1	Development of trapeze system for dinghy sailing Söderström, Ingrid, Gustafsson, Johanna January 2008 (has links) This is a Bachelor degree project report describing the development process of a trapeze system for dinghy sailing. The project was performed in cooperation with Seldén Mast AB, manufacturer of spars and rigging systems for yachts and dinghies. The trapeze system is used in some dinghy sailing classes. It is used to move the weight of the crew outside of the boat to compensate the force created by the wind in the sails. The system consists of a number of components. Focus of the project was set on the position adjustment device and the attachment to the harness. The product development process included a pre study, a Product Design Specification, a function analysis, concept development, embodiment, and detail design. The project resulted in three products: two variants of trapeze cleats (adjustment devices) and a trapeze ring (to enable attachment to the harness).

3	Self-locking Brake used in Reversible Sailboat Winches : Development of a self-locking braking system that will be used to allow sailboat winches to reverse Andersson, Lukas January 2022 (has links) Sailboat winches are used to help sailors manipulate the control lines that control the position and shape of the sails. Unlike most winches sailboat winches usually only have the ability to winch in the rope, but not to reverse. To reverse the line a sailor needs to manually manipulate it, this is both inconvenient and can also be a safety hazard. This master’s thesis will focus on the development of a self-locking braking system that will be used to allow a sailboat winch to reverse. The goal of the thesis is to design a braking system that works with a modified version of the E40i winch produced by Seldén. The braking system that was developed during this thesis is made up of two main parts, a one-way mechanism and a brake. The type of one-way mechanism that was chosen was an overrunning roller clutch. For the brake a wet disk brake was chosen with an outer diameter of 50mm and an inner diameter of 28.8mm. A 3D model of the braking system has been generated and materials have been selected so that the system is ready for prototyping and physical testing.
