Descriptive Note: SSC STV

(Rules and Regulations for the Classification of Ships, July 2022, Pt 1, Ch 2, 2.8 Descriptive notes 2.8.6)

The descriptive note STV is described in the Rules and Regulations for the Classification of Special Service Craft, July 2022 as: “
  • Where a sailing vessel is used for the offshore training of cadets or trainee seamen, a sailing training vessel STV descriptive note may be entered in column 6 of the Register Book.”
Guiding principles for this descriptive note are:
  1. Length to depth ratio is about 10. At this ratio, hull global strength calculations are unlikely to raise critical issues. The rig on the vessel is not expected to cause loads outside the range found in cargo vessels of this size and will therefore need no special consideration.
  2. The lower mast piece and the first bowsprit piece is typically welded into the hull and considered as the foundation/pedestal for the rig and therefore part of Class. These parts would therefore need to comply with Pt 3, Ch 9, 11 Wind propulsion systems of the Rules and Regulations for the Classification of Ships, July 2022 using builder-specified loadings.
  3. Chainplates would also need to comply with Pt 3, Ch 9, 11 Wind propulsion systems of the Rules and Regulations for the Classification of Ships, July 2022.
  4. A keel plate with a thickness that would withstand grounding and other accidental loads exists. With the excess in hull bending strength, consideration could be given in using Grade A steel.

This list may be incomplete and assignment will be done on a case by case basis.
