Marinas should review eyewear weekly during launch and more often during boating season, holiday weekends, or weather-driven traffic peaks.
Increase frequency when
- proven sun styles are thinning
- reader powers are missing
- the next peak period will outlast current stock
Use seasonal service levels
A waterfront store may need a much faster cadence in summer than in the off-season.
Reorder before the weekend
Plan around supplier lead time so inventory arrives before the demand period rather than after it.
