Subject 4 of 10

Before you go: planning, weather and loading

Before launching, make sure the trip suits your boat, crew and forecast. Leave a trip plan, check the boat and carrying limits, and keep fuel in reserve.

A skipper checks the weather on a phone at a boat ramp before launching, with the boat on its trailer.

Decide

Four situations at sea. Decide first, then read why.

A lifejacket-wearing skipper uses a phone beside a small powerboat secured on its starboard side to a Pittwater pontoon, with two lifejacket-wearing passengers seated aboard.

You are about to leave a Pittwater pontoon. Nobody ashore knows your route or return time. What should you do first?

Key points

  1. Leave a trip planSomeone ashore should know where you are going and when you expect to be back.
    1. Give the route, expected return, vessel details and number aboard.
    2. Log on and off with Marine Rescue NSW as recommended by TfNSW.
    3. Report a changed or extended trip; identify shelter options before leaving.
    4. Know the waterway rules and emergency actions; take extra care in cold water, especially alpine waters.
    Plan your passage
  2. Ready boat, ready crewCheck the boat and show everyone the safety equipment before departure.
    1. Match the boat and the driver's skills to the waterway.
    2. Check lifejackets and the correct equipment for the vessel and waters; keep them accessible.
    3. Prepare children for emergencies, lifejacket use and safe boarding; keep their bodies inside while underway.
    4. Check hatches open both ways and remain unlocked underway.
    Safety equipment
  3. Forecast, updates, eyes outsideCheck BoM before leaving and regularly while out, including the return conditions.
    1. Check warnings, wind changes, waves and swell, tides, visibility and local bar conditions.
    2. Gusts may be up to 40% stronger than the forecast average; maximum waves may be up to twice the forecast significant wave height.
    3. Threatening clouds or whitecaps: lifejackets on and head for shore.
    4. Choose a calmer trip or postpone if doubtful.
    Marine forecasts
  4. Limits and balance both matterStay within the people and weight limits, with heavy gear low and secured.
    1. Follow the powerboat's ABP or safety-label limits. Recreational powered boats other than sailing boats and PWC need a safety label visible to everyone aboard.
    2. Spread passengers and equipment evenly to keep the boat level and balanced.
    3. Too much weight aft lowers the stern and increases swamping risk.
    4. Reduce the load in poor conditions or on open water, as the handbook recommends.
    Know your boat's parts
  5. Fuel in thirdsPlan one third out, one third home and one third in reserve.
    1. Check that the planned legs fit those fuel allowances.
    2. Keep the reserve for unexpected events; changing conditions can alter fuel needs.
    3. Check fuel lines and filters, and check for leaks or petrol and LPG odours before switches or engine use.
    4. The handbook generally advises against ethanol-blended petrol for boats; biodiesel also has fuel-system risks. Ask about the blend before filling.
    Fuel and gas safety
  6. Fix it before you goA recent service does not replace today's checks.
    1. Check the engine, cooling water, steering, battery and lights.
    2. Check the bung is fitted, drains are clear and unusual bilge water is investigated.
    3. Carry a basic toolkit and suitable spares; use the correct charger for lithium batteries.
    4. Check LPG equipment, ropes and ready-to-use anchors. Professional servicing every year is recommended for powered vessels.
    Engine checks

Question 1/3

You leave a trip message for a relative before launching at Brooklyn. Which set of details best follows the handbook?

Worked case: A Pittwater picnic with an afternoon wind change

You plan a morning picnic trip on Pittwater, returning in the afternoon. The ramp is sheltered, but the BoM forecast shows strengthening winds before your return. Your boat has 60 litres of usable fuel, and the proposed outward leg is expected to use 15 litres. Picnic gear is piled beside the stern seats.

Before you read the solution: what would you do?

    True or false?

    Decide each statement before you see the answer.

    1. It is calm at the ramp, so the whole trip will be calm.

    2. The annual service means I can skip today's checks.

    3. A recent service does not replace today's checks.

    4. Stay within the people and weight limits, with heavy gear low and secured.

    5. We are under the passenger limit, so another heavy esky cannot matter.

    6. Someone ashore should know where you are going and when you expect to be back.

    7. The forecast wave height is the biggest wave I can meet.

    8. I told someone the destination, so they have everything they need.

    9. Half the fuel gets us there and half gets us home.

    10. Check BoM before leaving and regularly while out, including the return conditions.

    11. Plan one third out, one third home and one third in reserve.

    12. Check the boat and show everyone the safety equipment before departure.

    Exercise: Make a launch decision

    These are invented planning figures, not a fuel-range prediction. Your Lake Macquarie outing starts with 72 litres of usable fuel, and stronger winds are forecast for later.

    Step by step

    1. What should your trip message to someone ashore include?

      Show the solution

      Give enough information to describe the trip and vessel, including your estimated return and number aboard. Report changes to the plan (p. 66).

    2. Using the rule of thirds, how much of the 72 litres do you keep in reserve?

      Show the solution

      72 ÷ 3 = 24 litres in reserve. Plan another 24 litres for each leg; check the planned legs actually fit those allowances (pp. 67, 76).

    3. The ramp is calm, but the return route may be too rough for your boat later. What is the sound decision?

      Show the solution

      Plan for the conditions you may meet on the return as well as the outward leg. Choose a calmer option or postpone if conditions are doubtful (p. 70).

    4. You are within both carrying limits, but the stern sits low under a stack of heavy gear. What next?

      Show the solution

      Limits and weight distribution both matter. Stern-heavy loading increases the risk of swamping; heavy items belong low and secured (pp. 73–74).

    Now on your own

    Try a new plan for Port Hacking. You have 90 litres of usable fuel. Answer before reading the solutions.

    1. Under the rule of thirds, what is the planned outward fuel allowance?

    2. You decide to stay out longer than your logged return time. What should you do?

    3. Threatening clouds and whitecaps develop while you are out. What does the handbook advise?

    4. You are boarding a small dinghy for the trip. Which method follows the handbook?

    Topic 1 of 6

    Make a plan someone ashore can follow

    As skipper, you are responsible for the boat and everyone on board.

    Choose a route that suits the boat, your experience and the conditions. Work out how long the trip will take, check any special waterway restrictions, and identify places to shelter if the weather changes. Build experience on calm, quiet waterways. Take an experienced person along if you can. Boating Handbook, pp. 65–67.

    Before leaving, tell a friend or relative where you are going, your estimated return time, your vessel details and how many people are aboard. NSW safety advice also recommends logging on and off with Marine Rescue NSW, using the MarineRescue app, VHF channel 16 or phone. Update your contact and Marine Rescue if you change or extend the trip, then log off on return.

    Know the waterway rules before you leave: lookout, giving way, navigation marks and signals, safe speed and distance, alcohol limits and any towing rules that apply. Know your emergency actions and who to contact. If you are involved in or witness an incident, the handbook says you must stop and give as much help as possible; reporting to authorities may also be needed. Take extra care in cold water, especially alpine waters, because of cold shock and hypothermia. Boating Handbook, pp. 65–67.

    • Include the return leg in your plan, with shelter options along the way.
    • Take extra care to let someone know if you are going alone.
    • Have a compass and an up-to-date chart or map; a chart or map is required for open waters (p. 68).
