SHINC, SHEX, and SHEXUU terms relate to which aspect of chartering?

• A. Navigation routes.
• B. Cargo documentation.
• C. Laytime calculation, with SHINC counting all days, SHEX excluding Sundays/holidays, and SHEXUU excluding holidays unless work occurs.
• D. Insurance coverage.

Answer: (C)

These terms govern how laytime is counted in a charterparty. Laytime is the allotted period for loading or unloading, and these phrases set which days actually count toward that clock.

SHINC means Sundays and holidays are included in the tally, so every calendar day, including Sundays and holidays, counts toward the laytime. SHEX means Sundays and holidays are excluded, so the clock only runs on working days and pauses on Sundays/holidays. SHEXUU means Sundays and holidays are excluded unless there is actual work performed on those days; if work occurs, that day counts, otherwise it does not.

Understanding these rules helps explain why disputes or expectations about demurrage or dispatch arise, since the choice of which days count can significantly change how long the ship has to complete loading or unloading. These terms are specifically about laytime calculation, not navigation routes, cargo documentation, or insurance coverage.
