Building an Aluminum Catamaran: Shaft Brake Installation & Starboard Hull Reveal

Shaft Brake System Installation

• 💡 The shaft brake is essential for stopping the propeller shaft from rotating, which is necessary for feathering the Bruntons EcoStar prop blades.
• ⚙️ This system functions similarly to a car's disc brake, with a caliper that engages a disc mounted on the shaft to prevent rotation.
• ⚡ The brake allows for feathering the props to reduce drag under sail and also enables power generation in regen mode by allowing blades to spin for electricity.
• 🛠️ The design evolved through several iterations, incorporating a floating bracket with acetyl bushings and bolts to allow self-centering on the disc and accommodate engine movement.

Starboard Hull Progress and Layout Decisions

• 🚢 Significant progress is made in the starboard hull, with the installation of a large bulkhead and flooring panels.
• 🚪 A key decision involves relocating the cabin door to be just before the head entrance, creating a more open feel in the master cabin.
• 🚽 The head layout is finalized, with the toilet, sink, and shower space planned, and consideration given to raising the toilet for better space utilization.
• ✅ Hatches are fitted with latches, and the flooring is recessed and flush, marking a major step in completing the starboard hull.

Farewell to Super Ryan
