It is a general misconception, even with sail makers, that cruising sails are the cheap option.
My cruising sails are as expensive as my racing sails. They have the same complex cut and all other racing options such as a small Cunningham block and windows above the boom and at spreader height, and bungee instead of cord. The only difference is they are not made from racing cloth and don’t have to be carefully rolled before I shoot a bridge. Because they have reefing cringles and enforcements and a buoyancy pocket they are about as expensive as racing sails despite the slightly cheaper cloth used.
If you want cheap sails, ask your sail maker for cheap sails!
