Additional information
Choose Your Cover Fabric
7 oz. Polyester — Our entry-level marine cover fabric, woven from 100% polyester fiber at a 7 oz. per linear yard weight. This lighter option keeps the cover manageable for solo handling while still delivering reliable protection against sun, rain, and debris. Backed by a 3-year fabric warranty. Ships in Black.
9 oz. Polyester — Step up to our heavy-duty polyester, engineered at 9 oz. per linear yard for boats that face tougher conditions or extended outdoor storage. The denser weave adds an extra layer of defense against abrasion and weather without adding unnecessary bulk. Protected by a 5-year fabric warranty. Ships in Navy or Black.
Sunbrella® — For boaters who want the best, our Sunbrella covers use 100% solution-dyed acrylic — the same fabric trusted by marine professionals worldwide. Naturally resistant to fading, mold, and water damage, Sunbrella holds its color and integrity season after season. Covered by a 6-year fabric warranty. Ships in Black, Smoke, or Marine Blue.
Both polyester options feature solution-dyed construction, where pigment is infused into each fiber during production rather than applied to the surface afterward. This process locks color deep into the material, preventing any dye transfer to your boat’s gel coat or finish. The result is a cover that stays vibrant without bleeding or rubbing off. Our polyester is also designed to breathe — it allows moisture trapped underneath to vent out naturally, reducing the risk of mildew and keeping your boat dry. The fabric holds its form without sagging or stretching over time, stays lightweight enough for one person to handle, and stands up to prolonged UV exposure and harsh marine weather.

Frequently Asked Questions
The 231 Coastal is NauticStar's "Swiss Army Knife" — a boat that bridges bay fishing and offshore capability with equal competence. Unlike the deep-V XS series optimized for canyon fishing, the Coastal series features modified-V hulls that excel in shallow bays, inlets, and near-coastal waters while retaining genuine offshore range. The 231 Coastal is the flagship of this hybrid approach: small enough to access shallow Louisiana marshes with its 14-inch draft, large enough to run 50+ miles offshore to wrecks and structure, and comfortable enough for extended trips with head compartment and dual aerated livewells.
The optional Sport Package transforms the 231 from a fishing platform to a family cruise boat by adding a swim platform (for cooling off during long runs), a bimini top (providing shade forward of the T-Top), and a premium Fusion stereo system (making extended trips enjoyable for non-anglers). These features allow the 231 to transition seamlessly from tournament fishing format to family day cruising — a genuine hybrid capability that dedicated bay boats or offshore boats simply cannot match.
Yes. Every NauticStar model, regardless of series, features 100% wood-free composite hull — no wooden stringers, transom core, or deck framing. The 231's hull bonds directly to the deck with stainless steel screws on 2-inch centers, chemically sealed and protected by vinyl ester resin barrier coat. This construction backs the Limited Lifetime Hull Warranty and 5-year NauticGuard extended coverage, ensuring that a hybrid model receives identical structural protection as specialized offshore boats.
The 231 features 43 gallons of total aerated livewell capacity: a 30-gallon aft livewell and a 13-gallon forward livewell, both plumbed and aerated. This capacity accommodates tournament-format bay fishing (keeping quality redfish, flounder, snapper for weigh-in) while also supporting offshore fishing formats that prioritize large gamefish and live-bait presentations. The T-Top cover shields both livewells from UV degradation and salt spray.
The 14-inch draft is 1–6 inches shallower than XS models, allowing the 231 to access shallow-water structure like seagrass flats, marsh creeks, and sandy shoals where deeper boats run aground. This shallow-water capability combined with 50+ mile offshore range makes the 231 genuinely capable of fishing both environments in a single day — an advantage that neither pure bay boats nor offshore-only boats can claim.
The 231 includes NauticStar's proprietary STAR Performance System: air-assist chines that reduce hull pressure during acceleration, planing pods beneath the transom that flatten the running attitude at cruise speed, and a sharp-entry V-hull design. Together, these features improve fuel economy (typically 3–4 MPG with single 200 HP engine), enhance handling in rolling seas, and deliver faster hole shot compared to traditional modified-V boats without performance enhancement.
The wrap-around deck eliminates steps and obstacles, creating continuous fishable space from helm to stern. This unified deck surface is particularly valuable for sight-casting presentations where anglers need unobstructed footing and clear sightlines. The T-Top cover protects the entire wrap-around surface from UV and salt spray, preserving the gel-coat finish and making the 231 appear newer longer than competitive boats.
The 231's 10-person capacity is designed for day-trip use with maximum crew, not overnight sleeping. The head compartment provides essential bathroom facilities, and the on-board coolers with fresh water allow extended trips (all-day fishing runs, tournament circuits). However, for true liveaboard capability, larger models like the 28 XS with full cabins are better suited.
Yes. The 231 is engineered for both: a single 200 HP outboard (up to 250 HP max) for recreational fishing and exceptional fuel economy, or twin 150 HP engines for redundancy and moderate speed increase. The 2,650 lb dry weight allows all configurations to perform smoothly, with single-engine efficiency taking priority in most recreational use.
The optional bimini top mounts forward of the T-Top hardtop, creating a shaded helm area without obstructing the T-Top cover's fit. Our custom pattern accommodates the bimini's frame and support structure, ensuring the cover drapes cleanly around all hardware. For anglers without the Sport Package, the standard T-Top installation requires no modifications.
NauticStar 231 Coastal T-Top Boat Cover
The NauticStar 231 Coastal is the boat that refuses to choose — a 22’9″ hybrid platform that delivers authentic shallow-water bay capability and genuine offshore performance from the same platform. With a 14-inch draft, the 231 runs Louisiana marshes and Florida flats like a true bay boat, yet the 79-gallon fuel capacity and modified-V STAR Performance System hull provide 50+ mile range to offshore wrecks, continental shelf structure, and Gulf Stream fisheries. The 231 bridges the gulf between dedicated bay boats and offshore specialists, allowing anglers to pursue trophy redfish in the morning, then transition to deep-water snapper and grouper in the afternoon — all from one boat with one set of systems and maintenance routines. The optional Sport Package adds a swim platform, bimini top, and premium Fusion stereo, transforming the 231 from tournament fishing platform to family cruise boat in seconds.
Built in Amory, Mississippi, the 231 Coastal is constructed with NauticStar’s revolutionary 100% wood-free composite hull — no wooden stringers, transom core, or deck framing that can rot or delaminate. The hull bonds directly to the deck with stainless steel screws on 2-inch centers, chemically sealed and protected by vinyl ester resin barrier coat that eliminates osmotic blistering. The 231’s Limited Lifetime Hull Warranty and 5-year NauticGuard extended coverage back this hybrid-series boat with identical structural protection as flagship offshore models.
A Perfect Fit custom T-Top cover wraps the entire 231 deck and console — dual aerated livewells, insulated fish boxes, rod holders, optional Sport Package hardware, head compartment, on-board coolers, all electronics, and every stainless steel connection — under UV-resistant, salt-proof solution-dyed marine fabric. Our pattern is engineered to the 231’s specific hull contours, including its wrap-around deck design and 8’6″ beam, with reinforced stitching at stress points and adjustable tie-downs that secure to the rubrail. Whether the 231 is anchored at a shallow-water tournament venue or stored at a full-service marina, the cover preserves every system and surface for years of hybrid-series performance.
The Hybrid Fishing Advantage
The 231 Coastal’s true power lies in its refusal to specialize. Traditional angler choices have always been binary: bay boat for shallow water (but limited offshore range), or offshore boat for distance (but can’t fish shallow structure). The 231 eliminates this choice. The 14-inch draft accesses grass flats and marsh creeks; the 79-gallon fuel capacity provides 100+ miles of range; the modified-V hull with STAR Performance System optimizes both shallow-water turning and offshore planing efficiency. This is a boat for anglers who fish multiple environments and refuse to buy two boats to do it.
The dual aerated livewells provide 43 gallons of total capacity — adequate for tournament bay formats where quality matters more than quantity, and sufficient for offshore fishing where live-bait presentations demand multiple species. The two on-board coolers serve dual purposes: keeping drinks cold during bay runs, and preserving catches during offshore transitions. The wrap-around deck eliminates obstacles to sight-casting, while the optional head compartment supports extended all-day and overnight trips.
STAR Performance System Engineering
The 231’s air-assist chines reduce water pressure against the outer hull during acceleration, creating a wider planning surface and reducing fuel consumption. Planing pods beneath the transom flatten the running attitude at cruise speed, improving efficiency and comfort in rolling seas. The sharp-entry V-hull design combines these innovations into a boat that outperforms traditional modified-V competitors in both acceleration and fuel economy — typically delivering 3–4 MPG with single-engine power, and excellent planing characteristics even when loaded for offshore tournaments.
