Highlights
Outing Highlights
A shallow-water 21' Sport built for anglers
The 21' Shallow Sport uses the Quadrahedral Double Tunnel design with raised gunwales, a configuration favored by guides because it tracks straight, tolerates 2–3' chop, and lets anglers stalk targeted shallow areas and land fish with ease.
Six-person capacity and safety gear included
Rentals fit up to six passengers and include all required USCG safety equipment; boats start with a full tank of fuel, though renters are charged for fuel used.
Flexible rental lengths with a minimum
Available rental windows run from short trips to multi-hour outings (including an Early Bird session), with a three-hour minimum—planning around these blocks will shape any productive day on the water.
What the day feels like
What the outing feels like
A rental on the 21’ Shallow Sport is a focused inshore day: the hull lets you slip across the flats and into skinny-water ambush points, track straight while you stalk targeted areas, and give anglers room to work the sides for easy netting and releasing of fish—while the boat’s stability handles typical bay chop so the day stays about fishing, not the ride.
