Squat / UKC Calculator

Calculate squat and under keel clearance at high water.

Least Charted Depth (m)

Height of Tide at HW (m)

Block Coefficient (Cb)

Transit Speed (knots)

Vessel Static Deep Draft (m)

UKC at HW

--m

Water Depth at HW--

Max Static Draft--

Squat--

Squat = 2 × Cb × V² / 100 · UKC = Water depth at HW − Draft − Squat
