Danu

the livery

Put your name on a submarine

Danu is a five-figure, multi-year, father-daughter build — documented completely in the open. Sponsors ride along the old racing way: your sticker on the hull, in every build photo, and — at the higher tiers — to the bottom of Lake Michigan and back on camera.

Where stickers live

Real estate on a 4-inch submarine is genuinely scarce — that's the fun of it. Zones are referenced in the tiers below.

ABBCCDDA — top billing, forward flank (1)B — flank billboards (2)C — tail fins (4)D — sail & fairing spots (up to 20)marine vinyl · placements flex with fit & flow

The wall

Waiting on its first name. In navy tradition, the original crew of a new ship are her plank owners — that spot is open.

The honest fine print.Danu isn't a nonprofit — sponsorship is support and visibility, not a tax-deductible donation. Sponsorship never buys influence: missions, safety rules, and the look-film-never-take ethic are governed by the Requirementsand aren't for sale. Stickers are marine vinyl; exact placement flexes with hydrodynamics and fit, and season = one Lake Michigan expedition season. We'll always be straight with you about timelines — this is a build-in-the-open hobby project with a day job attached.
