The transom knot is a simple lashing knot used to secure two linear objects, such as spars, at right angles to each other.

Relation to other knots

[edit]

While often described in relation to the constrictor knot, the underlying structure of the transom knot is the strangle knot.[1][2] The introduction of a second, perpendicular spar into a loose strangle knot tied around another spar will illustrate this point. In relation to the upper spar, the crossings of the knot come to very closely resemble those of a constrictor knot.

Perhaps because of this Clifford Ashley described the transom knot as both "a modification of"[3] and "closely related to"[4] the constrictor knot. Despite these descriptions the transom knot is consistently illustrated in The Ashley Book of Knots as being based on a strangle knot.

Use

[edit]

Suggested for binding kite sticks by Ashley,[5] it is useful generally as a light-duty or temporary square lashing. To reinforce, a second transom knot can be made on the opposite side and at a right-angle to the first.[2][5]
