Boat Log & Maintenance
Read full descriptionHide full description
Helm is a boat logbook for owners who look after their own boats: engine hours, maintenance, trips and costs in one place. ENGINE HOURS FROM YOUR TRIPS Log a trip with the engine hours at start and finish, or just the hours run, and Helm keeps each boat's running total. Every maintenance item works out what is due from it. MAINTENANCE BY HOURS OR DATE Set each task by engine hours, by calendar, or whichever comes first. When you add a boat, Helm sets up a starter schedule for its engine type, such as oil and filter, impeller, lower unit or gear oil, zincs, battery and safety equipment. The starter intervals are general guidelines and your owner's manual has the final word: open any task to change its interval or enter when the job was last done. The dashboard shows what is coming due and what is overdue, and with notifications on, a reminder arrives a week before a calendar due date. Log each service with who did it, the engine hours, the cost and notes, and see each task's service history. TRIP LOG Date, departure and return times, engine hours, fuel used in gallons or liters and its cost, purpose (cruising, fishing, watersports, sailing, racing and more), passengers, departure point and destination, weather, sea state and notes. Each trip shows the price you paid per gallon or liter. EXPENSES Log fuel, marina or slip fees, insurance, registration, parts and labor, upgrades, cleaning, trailer, winter storage, haul-out, electronics and more, with a receipt photo, in your own currency. Open any expense to edit or delete it. SAFETY Run the pre-departure checklist before you leave the dock: fuel and oil, bilge pump, fire extinguisher, flares, life jackets, VHF radio on channel 16, navigation lights, float plan, weather, propeller, battery and a safety briefing for passengers. The man overboard reference, including the MAYDAY call on VHF channel 16, works offline. FREE 1 boat, 20 trips, the starter maintenance schedule plus 5 tasks of your own, expenses, the pre-departure checklist and the man overboard reference. HELM PRO - Unlimited boats, trips and maintenance tasks - Expense analytics: total spent, monthly average, category breakdown and cost per engine hour - Fuel analytics: total fuel and cost, fuel per engine hour, the average price per gallon or liter, fuel cost per engine hour and the trend by trip - Export: a CSV of your trips, expenses and services, and for any of your boats a trip log PDF, an expense report PDF and a full vessel report PDF with its service history, useful when you sell your boat Helm Pro is a monthly or yearly subscription that renews automatically.
