Ainsley, dropping the mast is easy , pair of parrot beak wire cutters .....no ...scratch that....seriously, providing all is well and nothing is seized or difficult to undo it should be easy to lower. Make sure there are at least two able bodied people on your first try , although three might be better
My suggestion:
1. If you have a clevis pin on your forestay (google it) make sure it can be easily removed, wd40. Same for the mast base pin. Close the sliding hatch you don't want open holes while your lambardering with a mast .
2. Have person put a little forward pressure on the mast to relieve forestay tension, you may need to release tension on the backstay.
3. Remove clevis pin or whatever method you have attaching the forestay.
4. Slowly lower the mast backwards with two people,
ensuring you to not let it sway sideways.
5. As you get to the cabin roof step have one ( preferably stronger)person step down to seats while the other holds the mast steady .
6. Lower the mast to the dummy on the seat ...sorry lower person

this person will be able to take the weight till the top person joins them .
7. Lower the mast gently to the taffrail , if you don't have a rear rail place a board across the side rails, you don't want the mast too low till you remove the the mast base pin.
8. Remove the mast base pin and then move the mast forward till its balanced on the boat.
9. Beers all round.
Most people have some form of mast crutch at the rear . This is handy for raising the mast as it gives you a head start weight wise and worth making one . Not all that necessary for lowering ?
