When you're shopping for marine safety survival gear, the first question isn't always price-it's how the jacket will actually behave around water. West Marine produces inflatable PFDs with different triggers: some fire automatically on immersion, some wait for you to pull a lanyard, and some do both. The four listings here cover that range: two inshore automatic/manual life jackets, an offshore automatic model, and a manual Type V adult vest. Your choice depends on how many jackets you need, where you boat, and how much hands-on control you want.
Quick take
- The West Marine Inshore Automatic/Manual A/M-24 (New with tags) combines automatic immersion inflation with a manual pull handle.
- If you need two jackets, the pre-owned pair of A/M-24 jackets is the practical way to cover two adults.
- The Offshore Automatic Inflatable Life Jacket A-33 is designed for open-water time.
- The West Marine Manual Inflatable PFD Type V (Model 1131) shifts the trigger to you, with a jerk-to-inflate lanyard and a CO2 cylinder already installed.

Decision matrix
- Choose the new A/M-24 if you want automatic protection but also want the option to switch to manual-only when paddling or fly-fishing, and you prefer a single jacket over a two-pack.
- Choose the two-jacket bundle if you need to equip two adult boaters and don't mind pre-owned condition because the jackets are described as never wet or inflated.
- Choose the A-33 if your outings lean offshore or open-water and you want an automatic jacket that doesn't require a manual trigger.
- Choose the Type V manual if you want a straightforward vest with a manual lanyard, and you're comfortable being responsible for the inflation trigger.
Product notes
2 - WEST MARINE Inshore Automatic/Manual Inflatable Life Jacket Blue

The two-jacket listing is really about covering two adults at once. Each jacket is a West Marine A/M-24 that can inflate automatically on immersion or be converted to manual-only inflation for kayaking, canoeing, or fly-fishing, and the set comes with two CO2 rearm kits and two lanyards with whistles. The jackets are described as like new, never wet, and never inflated. The trade-off is that this is the pre-owned option in the group, so the attached rearm kit cylinders and overall condition matter more than with the new-with-tags jacket. If the double coverage isn't needed, the single new jacket is less expensive.
WEST MARINE Inshore Automatic/Manual Inflatable Life Jacket Blue - NEW

The new A/M-24 keeps the automatic and manual triggers in one jacket. It's listed with tags still on it and includes automatic inflation when hit with water, plus a jerk-to-inflate handle for manual use. West Marine positions it as a convertible jacket, so you can set it to manual operation for wet activities. The backup oral inflation tube is a useful addition. Since it's a single jacket, it doesn't solve the question of equipping a second boater; that's where the two-pack listing becomes relevant. For one adult, this is the cleanest way to get the automatic/manual combo without paying the offshore premium.
Offshore Automatic Inflatable Life Jacket A-33 from West Marine. New, Never used

The Offshore Automatic A-33 is the only jacket in this set built for open-water boating. It's described as both comfortable and safe for sailing, fishing, and recreational boating, and it inflates automatically when needed. The jacket is new and never used, though the tags are off, so it hasn't been through a previous owner's wear. The limitation is the listed price: it's the most expensive of the four, and the overall concept is less flexible than the A/M-24 because it's focused solely on automatic inflation. If you're strictly paddling in calm inshore water, the automatic-only approach may be more automation than you need.
West Marine Manual Inflatable PFD Life Jacket Type V Adult Boating Vest & Co2

The Type V manual vest takes the opposite approach: no automatic trigger at all. You control inflation with the jerk-to-inflate lanyard, and the listing includes a 25g CO2 cylinder plus a Halkey-Roberts 840 inflator already installed. It's listed as new unused with no tags, fits adult chest sizes 30 to 52 inches and users over 80 pounds, and the description includes a USCG approval reference. The manual nature is the main limitation, because it won't inflate on its own when it contacts water. This one is for boaters who want a simple, deliberate jacket and are comfortable being responsible for the trigger.
Final recommendation by use case
- Best fit for most inshore paddlers and anglers: the new West Marine Inshore Automatic/Manual A/M-24. It gives you automatic inflation plus the flexibility to set it to manual mode for wet conditions, at the lowest single-jacket price here.
- Best fit for two adults on the same boat: the pre-owned pair of A/M-24 jackets. You get two vests plus the extras included in the set.
- Best fit for offshore or open-water cruises: the Offshore A-33 automatic jacket. It's the highest-priced option and the only one specifically framed around offshore use.
- Best fit for manual-only shoppers: the West Marine Type V Manual vest. It's a straightforward pull-and-inflate design for adults who want to manage inflation themselves.
