More boat control
Add the ability reef sails, fine tune, change sail type and switch between a genoa or a jib on available boats,
While I agree it would be nice to be able to change sails, there is little point while the level of wind makes no difference to how the boat sails. In order to make sail changes/reffing necessary the amount of heel needs to change with the amount of pressure from the sails and thus speed may be compromised with excessive heel, requiring sail changes/reef to maintain stability.
