Port tariffs and port charges

Stowlines keeps your port tariffs port by port and prices each call from them, with the charges on the vessel's GRT, NRT, LOA or TEU, in slabs or bands, with weekend and holiday surcharges where the tariff has them. Port cost calculator

Weather along the route

The weather check shows the forecast along the voyage's sea route and live storms against the itinerary. The Weather / Current setting shows the effect on the days and the fuel. It informs your decision: it does not choose a route for you. Ship weather check

Speed, deviation and route comparison

Compare speeds and routes side by side, and see what a deviation adds in distance, days and cost. You pick the options; the estimate shows what each one costs. Vessel speed optimization

• Speed optimization
• Estimated deviation distance
• Deviation cost calculation

Slots, capacity and utilization

Enter the vessel's capacity, nominal or effective, and the Load TEU of each leg. The estimate shows the cost per TEU, the utilization and the break-even utilization. Vessel capacity utilization calculator

Revenue, profit and break-even

Enter the freight of each leg and the estimate shows the revenue, the profit or loss, the margin, the profit per TEU and the break-even. The profit is the voyage result: revenue less the voyage costs you enter. Slots chartered out or exchanged count in a leg's Load TEU at the leg's average rate. Voyage P&L calculator

Voyage estimating and costing

Enter the vessel and the port rotation and see the whole voyage: days, bunkers, port costs, canal dues, hire and the result. It runs online, for container vessels and feeders, and every figure stays yours to change. Vessel voyage estimator

Fuel and bunkers

The fuel burnt follows the vessel's own speed-wise consumption, at sea and in port, and you enter the fuel prices. Time at anchorage is entered as idle days, and there is no separate manoeuvring figure: allow for it in the port consumption. Ship fuel consumption calculator

Sea distance and routes

Sea distances between 1,300+ ports on the route ships sail, free and with no sign-up, and the route of a whole rotation on the map in the estimator. It is for planning and costing, not for navigation. Sea distance calculator

Transit time and schedules

Sailing days and ETAs follow the distance, the speed and the port stays, and Schedule Planning keeps every voyage of a service on one board, with weekly berth windows. ETAs are worked out from the plan you enter, not from live ship tracking. Transit time calculator

Vessel sizes

The estimator works from your own vessel, so it gives these figures for your ship and not a general average. Vessel capacity utilization calculator

• 2500 TEU Container Vessel Voyage Cost
• 1700 TEU Feeder Vessel Operating Cost

Budgets, templates and Excel

Build the voyage online, save it as a template, and take the estimate to Excel, PDF or PowerPoint. There is no blank sheet to fill in: the workbook comes with the voyage worked out. Voyage budget template

What Stowlines does not do today

People search for these, so here is the plain answer. There is no automatic weather routing or route optimization: you compare the routes and speeds yourself. It does not plan navigation or passages, which stay with the ship. It does not work out a vessel's intake. It has no comparison of actual results against the budget, no schedule reliability or weather performance analysis, and it shows the margin and the profit rather than a return on investment.
