Holtrop - Transom Resistance
Transom-stern resistance component R_TR per Holtrop - accounts for wave-breaking at a wetted transom.
Transom resistance
65.4kN
Formula, assumptions, and limits
c_6 vanishes when Fn_T > 5 (transom runs dry). Design transom stern to just clear at service speed - minimises R_TR. Container/ro-pax ships typically Fn_T = 4–6.
