So many questions with so many answers.
Regarding cranage, it depends on the size/weight of the boat, one option is to be craned to the River Carron at Grangemouth and enter the canal at the Kelpies.
Why don't you walk along the canal and talk with existing boat owners.
There may some disillusioned owners who are interested in selling their boat which already on the canal thereby saving a lot of money in transportation.
Maintenance facilities on the canal are very limited.
Hope things work out for you.
