It is, when the boat is set so (original rig design).
Remember not all boats that were built with lowering mast as an option ever lowered their masts. Some owners do it daily, others maybe never.
Observe at least the following:
- is she a ketch
, if so, do you have to lower the mizzen too?
- is there a furler jib
on the main mast?
- has any heavy gear
been added to the masts (radar domes, etc)?
- is the rigging
original layout, or modified (a fixed triatic???)?
Mind the designer
had it all right. You do not need a frame with mizzen and tabernacles (the main mast lowers fore unless the tabernacle is gated at the back) BUT now and then inventive owners/riggers can 'adjust' things making it more difficult to lower the masts.
Ask the owner for a demonstration. After all, they will know best how it is done on their specific boat.
By design, it was very easy on the Dutch boats.
