Swamp Hauler 15
Budget welded-aluminum modified-V jon for skinny water: wide, shallow, starboard (right) console with wheel, live well, two bait wells, ice well, bait cooler and drink wells.
Rev D: console is on the starboard (right) side — not a starboard console. Open walkway on port. Helm includes speedo/tach/fuel/volt gauges, marine stereo, and a small plexiglass windshield. Concept design. Not certified naval architecture or a certified drawing — a qualified welder/boat builder must review before cutting metal. Verify capacity and flotation per USCG 33 CFR 183. Prices are estimates (Oct 2026 USD); nothing here is a purchase.
Concept renders (rev C)
AI concept renders — not photos of a finished boat.




Rev C: the blunt/pointed entry is replaced with a flat ramped skid-style bow like a classic aluminum jon — one flat 0.125" bow plate ramping up ~30° over ~33", squared at the deck, no stem weld.
