The part of the stern above the waterline that extends beyond the rudder stock culminating in a small transom. A long counter increases the waterline length when the boat is heeled, so increasing hull speed.



Related Terms

LOA

The maximum length of a vessel's hull measured parallel to the waterline, usually measured on the hull alone, and including overhanging ends that extend beyond the main bow and main stern perpendicular members. For sailing vessels, this may exclude the bowsprit and other fittings added to the hull, but sometimes bowsprits are included.

FREEBOARD LENGTH

(L): Taken as 96% of total water-line length, situated at 85 % of the least moulded depth or, if greater, as the length from the fore side of the stem to the axis of the rudder stock on that water-line.

LENGTH BPP

The length of a vessel along the waterline from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. Believed to give a reasonable idea of the vessel's carrying capacity, as it excludes the small, often unusable volume contained in her overhanging ends.

TAFFRAIL

The rail at the stern of the boat that covers the head of the counter timbers.

LPP

The length of a vessel along the waterline from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. Believed to give a reasonable idea of the vessel's carrying capacity, as it excludes the small, often unusable volume contained in her overhanging ends.

RUDDER STOCK

A vertical rudder shaft that connects to the steering gear

AFTER PERPENDICULARS

A vertical line at the intersection of the summer load line and the after side of the rudder post or sternpost, or the centerline of the rudder stock if there is no rudder post or sternpost

HARD CHINE

An abrupt intersection between the hull side and the hull bottom of a boat so constructed.

DEAD WATER

The water carried along with a ship as it moves through the water. It is maximum at the waterline and decreases with depth. It increases in a direction towards the stern

TRANSOM STERN

A square-ended stern used to provide additional hull volume and deck space aft and to decrease resistance in some high speed ships.
