Marina & Boatyard Economics: Berth Mix by Length, Annual, Seasonal & Visitor Nights, Waiting Lists and Berth Fit, Fuel Dock, Haul-Outs & Winter Storage, Pontoon & Dredging Reserves and Break-Even

What you'll build

What you will be able to do

Each lab ends with a concrete result that you build yourself and the checker confirms, cell by cell.

• Turn a marina's berth list into potential and actual contract revenue by length band and compare occupancy counted in berths with occupancy counted in metres.
• Price visitor nights by season, measure how full the visitor pontoon really was and compare the visitor business with letting the same pontoon to seasonal boats.
• Match boats on the waiting list to free berths with a length and width rule, find the smallest berth that fits each boat, count the options and price the revenue lost when a small boat takes a large berth.
• Compute the fuel margin per litre after the card fee as buy prices change, add up the season's fuel margin and measure how many fuel-dock visits turn into a chandlery sale.
• Sort boats between the travel lift and a hired crane with a fictional booking rule, add up the hard-standing area they need, see how many more boats fit and date the last haul-out day with WORKDAY.
• Estimate the hull area with the yard's fictional rule of thumb, turn the fictional product label into whole tins, build the labour from fixed and per-m² jobs and price the full quote with a materials markup.
• Date the next replacement of each pontoon and the next dredging, inflate today's costs to the year they fall due, compute the yearly reserve contribution with PMT and turn the total into a surcharge per berth-metre.
• Add berth contracts and metered shore power to the other income streams, set them against the costs, find the metre occupancy at which the marina breaks even, test a rate increase with some lost boats and chart where the money goes.
