Catamaran Purchase & Cruising Budget Calculator

Three numbers decide whether your cruising dream sails or sinks.
The purchase price you can really afford
Your cruising budget, year after year
The refit and yard periods nobody budgets for
Get one wrong and the plan unravels: you cut the cruise short, or sell in a hurry, in the wrong place, at the wrong price. This calculator puts all three numbers side by side, so you see the whole picture before you commit to a boat.
What's inside
Cruising Budget Estimator: monthly and yearly costs for a 42-48ft catamaran crewed by a couple, across four lifestyles from marina full service to cruiser full DIY. Built from published owner data and my own costs cruising Coco, our Leopard 48.
Sabbatical test: does your fixed pot survive a fixed cruise, including the refit and what you get back when you sell?
Long-term liveaboard test: does your income cover your costs every year, including saving for the next yard period?
One-page Dashboard with a plain-English verdict: green, amber or red.
Pop-up tips on every input, plus teaching notes on the traps buyers fall into.
Who it's for
Two years out? Get your numbers right now and you have time to save, sell, plan your refit and pick the right boat, instead of rushing at the end.
