retrimming

Retrimming is the act of re-adjusting trimming or reshaping an object after an initial trim has been performed. It is used in contexts where conditions or requirements change, requiring renewed refinement to maintain form, balance, or efficiency.

In sailing, retrimming refers to readjusting the sails and rigging in response to shifting wind, velocity, or course. The crew modifies sheet tensions, halyard positions, and the angle of attack to preserve sails’ efficiency and the vessel’s balance. Retrimming may occur after tacks or gybes, when gusts alter wind direction, or when the vessel changes speed or heading. Effective retrimming depends on communication between the helmsman and sail trimmers, as well as the use of telltales, wind indicators, and feedback from the boat.

In horticulture and landscaping, retrimming can describe pruning newly grown shoots after an initial trim to shape shrubs or hedges. In crafts and manufacturing, retrimming refers to re-cutting or readjusting edges, hems, or trim pieces to refine fit, symmetry, or appearance after a first pass.

Overall, retrimming is a corrective or refining action applied whenever a prior trim needs adjustment to achieve better performance, aesthetics, or function. Related concepts include trimming, sail trim, and pruning in horticulture.
