A. PANJANG Lc

Panjang Lc diambil 96% dari keseluruhan panjang pada garis air di posisi 85% dari linggi bentuk terkecil Hc, diukur dari bagian atas lunas atau panjang dari sisi depan lunas haluan sampai garis sumbu tongkat kemudi pada garis air tersebut, jika nilainya lebih besar. Pada kapal yang dirancang dengan lunas miring, maka garis air tempat pengukuran panjang diambil sejajar dengan garis air rancangan.

B. LEBAR ( Breadth / B )

Lebar terbesar kapal yang diukur dari kulit kapal ( lambung ) bagian dalam

B = 16.4 m

C. TINGGI ( Depth / H )

Jarak vertical antara bidang basis (alas kapal ) dengan pinggir atas balok geladak kontinyu teratas diukur pada pertengahan panjang kapal.

H = 7.8 m

D. SARAT ( Draught / T )

Jarak vertical antara bidang basis dengan lambung timbul untuk garis muat musim panas diukur pada pertengahan panjang L.

T = 3 m
