Hi Duncan, RS Aeros are designed for travelling stacked so when stationary in the garage it is an easy way to save space.
- Remove the quick release kicker cleat fitting
- Remove the quick release mainsheet block fitting (undo shackle on boats pre sail number of about 2100)
- Place all the lines and blocks at the mast step down the mast step
- Add padding in at least the 5 necessary points as per rigging manual
At rest in the garage as the RS Aero is so light you could happily store a load of gear on top of the top RS Aero. They are designed to be stacked 7 high, although tend to be transported with a max of 5.
Happy cycling!
