The Seachoice 78501 Folding Deck Chair in White (MPN 78501, UPC 719249785011) is a marine-grade folding deck chair designed for boat use – white UV-resistant marine vinyl seat and back over a 1-inch anodized aluminum tubing frame, with a safety locking device in the open position to prevent accidental folding while occupied. The chair folds flat for easy storage when not in use – critical for boats where storage space is at a premium. The 300-pound weight capacity covers virtually any single adult occupant including substantial body weight or operator wearing heavy clothing / gear. Marine-specific construction throughout: (1) UV-resistant marine vinyl that doesn’t degrade in extended sun exposure – typical household vinyl chairs fade, crack, and become brittle within a season of sun-exposed marine use. marine vinyl handles years of outdoor service. (2) Anodized aluminum tubing for the frame – the anodized surface treatment provides corrosion resistance in saltwater / marine environments where standard aluminum or steel tubing would corrode quickly. (3) Non-marking feet protect boat decks (gelcoat fiberglass, painted aluminum, teak / synthetic teak decking) from scuffs and marks that the typical metal-foot chair would cause. Easy to clean – use only soap and water, no special cleaners required. The chair fits standard adult dimensions with a 18.5-inch wide x 14-inch deep seat. Practical use cases: cockpit seating during fishing or cruising, deck seating during dockside relaxation, additional seating for guests on day cruises, deck chairs for stand-up paddleboarding rest spots or dinghy beach trips, folding chair for ship’s tender or shore landings. The folding design with locking mechanism is the safety-critical feature – the chair doesn’t accidentally fold while you’re sitting in it (a common failure mode of cheaper folding chairs that lack proper locking). Weighs 22 pounds – solid construction (not the lightest folding chair available, but the marine-grade construction adds weight vs cheap household chairs). Seachoice is one of the standard reference brands in mid-tier marine accessories with decades of field-proven product reliability across the recreational marine market.
The Seachoice 78501 Folding Deck Chair in White is a marine-grade folding deck chair designed for boat use – white UV-resistant marine vinyl seat and back over a 1-inch anodized aluminum tubing frame, with a safety locking device in the open position to prevent accidental folding while occupied.
Marine-grade vs household folding chairs. The 78501 looks similar to a typical household / patio folding chair, but the construction details that matter for marine use are different: (1) UV-resistant marine vinyl seat / back material – typical household vinyl fades, cracks, and becomes brittle within a season of sun-exposed marine use. The continuous UV exposure from sun reflection off water dramatically accelerates vinyl degradation vs land-based outdoor use. Marine vinyl is specifically formulated to handle this exposure for years of service. (2) Anodized aluminum tubing for the frame – standard aluminum or steel tubing corrodes in saltwater environments within seasons. The anodized surface treatment provides corrosion resistance for marine service. Hardware-store folding chairs often use plain steel or aluminum that develops corrosion immediately in marine use. (3) Stainless or marine-grade fasteners – bolts, screws, and rivets are marine-rated for corrosion resistance. (4) Non-marking feet – protect boat decks from scuffs and marks that the typical metal-foot chair would cause on gelcoat fiberglass, painted aluminum, or teak decking. The 78501 looks similar to a cheap chair but lasts substantially longer in marine service.
Safety locking device. The chair includes a locking device in the open position that prevents accidental folding while occupied. This is a safety-critical feature for marine chairs – boat motion (waves, wakes, sudden boat movements during maneuvering) can collapse non-locking folding chairs that depend only on weight and friction to stay open. The Seachoice locking mechanism positively secures the chair in the open position – the chair doesn’t accidentally fold even under significant lateral or vertical movement. To fold the chair for storage, deliberately release the lock and fold. To open the chair for use, unfold and verify the lock engaged before sitting. The locking mechanism is the difference between safe chair use and an embarrassing / potentially injurious collapse.
300-pound weight capacity. The chair handles up to 300 pounds of occupant weight – covers virtually any single adult including substantial body weight or operator wearing heavy clothing / fishing gear / foul weather gear. The 300-pound rating provides safety margin over typical body weights, accounting for dynamic loads from boat motion (sitting weight increases with vertical boat motion – a 200-pound person sitting in a chair while the boat dips down can momentarily apply 300+ pounds of force as the boat bounces back up). Don’t exceed the weight rating – the chair frame can fail with substantial impact load above the rating.
Folds for easy storage. The chair folds flat for storage when not in use. Practical implication for boats: storage space is at a premium on virtually any boat, and deck chairs that don’t fold compact significantly limit where they can be stored between uses. The Seachoice 78501 folds to a flat profile that stores efficiently in a lazarette, dock box, cabinet, or other compact storage location. Deploy when needed, fold and stow when not in use. For boats with multiple chairs, the folded chairs stack efficiently for compact storage.
Anodized aluminum frame. 1-inch anodized aluminum tubing forms the chair frame. Anodizing is the surface treatment process that creates a hard oxide layer on aluminum, providing corrosion resistance, color (anodized aluminum can be colored or left natural silver), and abrasion resistance. For marine service, anodized aluminum tubing handles continuous saltwater / marine environment exposure substantially better than plain aluminum. Standard aluminum tubing develops white powder corrosion deposits within seasons of marine use. anodized aluminum stays clean. The 1-inch tubing diameter provides structural strength for the 300-pound weight rating without the chair being excessively heavy.
Non-marking feet. The chair feet are non-marking material – protect boat decks from scuffs and marks. Typical metal-foot chairs leave marks on gelcoat fiberglass (the most common modern boat deck material), painted aluminum (typical aluminum boats), and teak / synthetic teak decking. The marks are usually permanent without sanding / refinishing. Non-marking feet eliminate this problem – move the chair around the deck without leaving any marks. For boats where deck appearance matters (newer boats, charter operations, brokerage boats kept ready for showing), non-marking feet are mandatory.
Clean with soap and water. The marine vinyl and anodized aluminum construction allows easy cleaning – soap and water removes typical dirt, salt spray, food spills, and general grime. No special cleaners required. AVOID: harsh chemicals, abrasive scrubbing, bleach, or solvents – these can damage the vinyl surface and degrade the anodized aluminum finish over time. For tough stains, marine vinyl cleaner / protectant products are available at any marine supply.
Seat dimensions. 18.5 inches wide x 14 inches deep – standard adult seating dimensions. Comfortable for typical adult body sizes during typical deck-chair use (relaxing, fishing, cruising in protected water). For very large operators or extended sit-down use (long offshore passages where you’d want a more substantial chair), heavier-duty deck chairs are available – but the Seachoice 78501 is appropriately sized for typical recreational marine use.
Practical use cases. Several scenarios where folding deck chairs are useful on boats: (1) Cockpit seating during fishing or cruising – additional seating beyond the boat’s built-in seats. (2) Deck seating during dockside relaxation – sit in the cockpit reading or socializing while at the dock or anchored. (3) Additional seating for guests on day cruises – the boat may have 2-3 fixed seats but you’re entertaining 4-6 people. (4) Dinghy beach trips – take chairs ashore for beach landings, picnic stops, gunkholing destinations. (5) Stand-up paddleboarding / kayaking rest spots – the chairs travel in the support boat for beach breaks. (6) Tender / shore landings – portable seating for shore expeditions from a cruising boat.
Color and aesthetic. White color is the standard marine deck chair color – matches typical white boat hulls / hardtops / decks, reflects solar heat better than dark colors (keeps the chair cooler in direct sun), and looks clean / fresh in the marine aesthetic. For boats with specific color preferences, Seachoice and other marine accessory brands offer alternative colors (typically gray, blue, beige variants).
22-pound weight. The chair weighs 22 pounds – solid construction. Not the lightest folding chair available (cheap plastic chairs weigh under 10 pounds), but the marine-grade construction (anodized aluminum, marine vinyl, proper locking mechanism) adds weight vs cheap household chairs. The weight provides stability when in use (the chair doesn’t blow over from typical breeze conditions) and durability for years of marine service. For ultralight portable chairs (camping / hiking applications), other product categories are more appropriate.
Warranty. Seachoice standard limited warranty applies. Save the receipt and the original packaging. Warranty service runs through Seachoice’s authorized service network. Most field failures Seachoice sees in the deck chair line are damage-related (impact damage from drops, exceeded weight limits, harsh chemical cleaning) rather than manufacturing defects – careful use delivers many years of reliable service.
