A detailed graphite sketch by Pieter van Loon depicting boats moored at the Nooij Kade in Utrecht, dated September 1855.

This graphite sketch by the Dutch artist Pieter van Loon captures a quiet moment of maritime activity at the Nooij Kade in Utrecht. Dated September 1855, the work demonstrates the artist's focus on observational recording, common among nineteenth-century draughtsmen who documented the changing urban and industrial character of the Netherlands. The composition centres on two moored vessels, their masts rising vertically against a sparse background. Van Loon employs a light, economical touch, using quick strokes to define the hulls and the rigging. The presence of figures on the decks and the inclusion of a ladder leaning against the cargo suggest a scene of routine labour rather than a staged picturesque view. The artist's inscription in the lower left corner provides a precise temporal and geographical anchor for the work, typical of the period's interest in topographical accuracy. The paper remains largely unworked, allowing the white space to represent the hazy atmosphere of the canal side. This sketch offers a direct, unadorned glimpse into the mid-nineteenth-century Dutch waterway system, where small-scale transport remained essential to local commerce. The lack of heavy shading or complex tonal modelling keeps the focus on the structural forms of the boats and the linear clarity of the scene. It is a functional piece of visual documentation, reflecting the artist's practice of sketching from life during his travels through the Dutch provinces.
