Information, policies and support for SMART SEAMEN.
True wind is the actual wind after allowing for the ship’s course and speed.
Use a guided three-step entry to calculate true wind from ship motion and observed relative wind.
Saved True Wind calculations
Calculate current and trial CPA/TCPA for own ship and a target ship using radar bearing and range.
Enter the own ship and target ship in Step 1, then test a delayed course or speed change in Step 2.
Reference use only — confirm every maneuver with approved bridge procedures and a proper lookout.
Saved Trial Maneuver calculations
Compare estimated squat at each speed before entering shallow or confined water.
Use the guided step-by-step wizard to enter vessel data, speed range, and water depth.
Reference use only — confirm under-keel clearance and shallow-water decisions with approved vessel procedures.
Saved Squat Table calculations
Cable scope compares the cable paid out with the total vertical depth from the bow to the seabed.
Use the guided three-step entry to compare several common cable scope methods.
Reference use only — confirm anchoring decisions with approved vessel procedures and current conditions.
Saved Cable Scope calculations
It calculates deadweight and maximum loadable cargo from displacement, lightship, allowances, and remaining on board quantities.
Use the guided entry to choose a ship and check the governing draft, displacement, deductions, and maximum loadable cargo.
Saved Deadweight calculations
Calculate cargo loaded or discharged from initial, intermediate, and final draft-survey readings.
Start a new survey with six draft marks, trim correction, hydrostatic interpolation, density correction, and ROB deductions.
Saved Draft Survey calculations
Use the active ship or enter a custom ship name and particulars for this survey.
Trimming is the difference between the aft and forward drafts. It helps you plan where cargo should be loaded so the vessel reaches the required trim safely.
Use the guided steps below to enter ship, draft, cargo, and trim data, then review and save the loading plan.
Reference use only — confirm every operational decision with approved shipboard stability information.
Saved Trimming calculations
Register a ship and its tanks, confirm the tank list, then enter draft readings and tank soundings for a trim-aware tank-volume calculation.
Prepare the ship and tank register first. Once confirmed, use the calculation screen to enter draft readings, see trim, and work through each tank sounding.
Registered ships and tanks
Saved Sounding calculations
Saved soundings for this ship
Enter available readings only. Trim is calculated when both Forward and Aft mean drafts are available.
Enter a sounding for each registered tank. The trim is shown in every row. Volume calculation will use the tank sounding table and trim-correction details that you define next.
It estimates an unreadable aft draft by using the readable side’s Fwd, Midship and Aft drafts with the other side’s Midship reading.
Use the guided three-step calculation when a draft mark is obstructed or cannot be read safely.
Saved Aft Draft predictions
Compass Error is the difference between the ship’s true course and compass course, combining variation and deviation.
Use a guided observation entry to compare celestial bearings with the ship’s gyro and compass data.
Saved Compass Error calculations
Build a port-to-port voyage plan before sailing. Add the departure, passage and arrival legs, then review distance, steaming time, ETA, fuel and fresh-water totals together.
Follow three short steps. You can review and edit every leg before calculating the complete voyage.
Saved voyage calculation results
Use distance and departure time to calculate an estimated time of arrival, or use a target arrival time to calculate the required speed.
Use the guided calculator to choose a ship, enter passage details, and review the ETA or required speed calculation.
