It all depends on the abilities and desires of each individual builder of course, and that is one of the big advantages of building your own boat.
I built my mast hollow using the birds mouth technique. This technique is a bit more work, but results in a mast that is up to 40% lighter and equal in strength to a solid wooden mast. The technique is well documented at duckworks. Its well worth the additional effort in my opinion. A lighter mast is not only easier to step and unstep, but reducing weight aloft also improves a sailboats performance.
Here is a short video that shows how easy it is to step, unstep and handle the mast on my Navigator. My mast weighs 17 lbs (7.7kg) not including hardware. It is not difficult to handle, and as you can see Im no athlete. If youre a Navigator builder, I hope this video helps you decide how to build your mast.
