Find the right gas springs to keep boat hatches, cabinets, and storage lids open safely and closed reliably. This guide highlights five top options that balance durability, corrosion resistance, and suitable lift force for common marine lids. Best for boaters who want reliable, rust‑proof performance in saltwater environments, these picks cover a range of extended lengths and forces to fit most hatch sizes.
Buying overview
- Best for everyday boat hatch use: Motoforti 7.5″ and ARISELIFT 10″ provide strong, corrosion-resistant stainless steel builds with balanced lift forces.
- Better for larger lids: Vepagoo 19.69″ (60 lb) and C1608316 style options handle heavier lids or cabinets in marine settings.
- Choose this if you need a compact, 8–9″ option: Hoffen 8-1/4″ 316 stainless steel offers rugged, compact support for flip‑up doors.
Motoforti 7.5 Inch Stainless Steel Hatch Gas Springs
Best for small to mid-sized boat hatches and compact cabinets. Extended length 7.5 inches, compressed 5.25 inches, with a 20 lb (90 N) force. Made of stainless steel to resist rust and corrosion in wet conditions. Suitable for marine hatch lids, cabin doors, and storage boxes. Best for boats that require a lighter lift and a compact fit. Caution: not ideal for very heavy lids beyond the 17–23 lb range.
Vepagoo 20 Inch Gas Struts (60Lb) For Marine Use
Best for larger boat hatches or RV lids where a higher weight capacity is needed. Extended length about 19.69 inches, 60 lb per strut (267 N), rust- and seawater-resistant 304 stainless steel. This pair is suitable for lids weighing 48–66 lb. Not including mounting hardware, so verify fit with your OEM hardware before purchase. Choose this if you need robust support for bigger marine lids; avoid if your lid is significantly lighter.
ARISELIFT 10 Inch Stainless Steel Gas Struts
Best for mid-sized boats and RVs with doors, trunks, or cabinets that need a steady lift. 10 inches extended length, 6.5 inches compressed, 20 lb (90 N) force. Stainless steel with anti-rust properties, suitable for rainy or snowy weather and wet conditions. Widely applicable for boat hatches, toolboxes, and cabinet doors. Limitation: may be less ideal for lids exceeding the stated 17–23 lb weight range.
Hoffen 316 Stainless Steel Hatch Spring (2 Pack)
Best for rugged marine bathrooms and cabinets where corrosion resistance is critical. 316 stainless steel construction resists rust in saltwater, with a heavy-duty design to reduce frequent replacements. Includes two springs designed to hold flip-up cabinet doors open or closed. Limitation: some installations may require bending or adjusting to fit non-standard lid lengths; ensure compatibility with your hinge points.
C16-08316 20 Inch 40Lb Gas Struts (2 Pack)
Best for larger RV and boat compartments requiring stronger support. Two 20-inch struts deliver 40 lb total lift per pair, suitable for heavier doors, boat hatches, and truck storage lids. Notable for centers with extended reach to accommodate bulkier lids. Caution: ensure the 20-inch extension fits your mounting geometry and that the lid weight falls within the 32–44 lb range for two struts.
Buying Guide
- What length and force do I need? Measure the open length (extended) and the lid weight. Select a strut whose extended length provides full clearance without over-extending the spring. Target a force that matches about 70–105% of the lid weight for smooth operation.
- Which material matters? Stainless steel (304 or 316) offers corrosion resistance in marine environments. 316 is generally more resistant to saltwater corrosion but may cost more.
- Are mounting holes compatible? Check end fittings (ball joint, eyelet) and hole sizes. Some sets require separate hardware; confirm compatibility with your hinges or brackets.
- Should I choose a pair or a single? Most marine hatches use two struts for balanced lift and security. Two struts provide even lifting and hold-open stability.
- Is weight range important? Lids generally fall within a weight range. Choose struts rated near the middle of your lid’s weight for best performance and longevity.
- What about environmental conditions? If you operate in wet, salty, or frozen environments, prioritize anti-rust stainless steel and robust seals to minimize rust and corrosion.
FAQ
What is a typical lift force for boat hatch gas springs?
Common values are 20 lb (90 N) per strut for mid-sized lids, with higher forces available for heavier lids, such as 60 lb per strut in larger applications.
Do I need mounting hardware included?
Many sets exclude mounting hardware. Verify whether brackets or screws are included or if you must source them separately.
Are these safe for use in saltwater environments?
Yes, choose models made from corrosion-resistant stainless steel (304 or 316) to resist rust and seawater exposure.
Can I install these on RV doors as well as boats?
Yes, many gas struts are suitable for RV doors, cabinets, and hatch lids, provided the length and force match the application.
How do I know if the lid is too heavy for the struts?
Refer to the listed weight range for the struts. If your lid is near or above the upper limit, upgrade to a higher force pair.
