Frequently Asked Questions:

What is the difference between a 170N and a 275N BackTow lifejacket?

People often ask us if they should make their lifejacket choice based on their body weight, but in reality it is more to do with the type of sailing you are planning. For overnight sailing, offshore weekend racing, coastal passages and cruising etc the 170N will be suitable for the majority of sailors. If you are heading off to do deep ocean crossings or sailing in very cold climates, we would recommend you consider the 275N lifejacket.

Both sizes of jacket are ISO approved, and they both are supplied within the same cover (this means that they are both the same size) It is what is inside the lifejacket that is different:

The 170N lifejacket has a bladder inside that will inflate automatically upon submersion (unless you have a Manual jacket system, in which case you must pull the yellow toggle to inflate your lifejacket) and it will provide 170N worth of buoyancy in the water. It uses a 38g CO2 cylinder for inflation. This will turn the wearer face-up if they are floating free in the water. Is it approved for use in inshore and offshore sailing, worn in combination with foul weather clothing. It is suitable for use in all but the most severe conditions.

The 275N lifejacket has a larger bladder inside and requires a larger (60g) Co2 bottle to inflate it. It will also inflate automatically upon submersion in water. It is intended primarily for offshore use in extreme conditions. It is also useful for sailors in very cold climates where you may be wearing extra clothing that could trap air around the body and adversely affect the self-righting capability of a smaller jacket.

What inflation systems are inside a TeamO BackTow Lifejacket?

There are different inflation systems for the different models:

Micro Lifejacket: 

Manual: the wearer must manually pull the handle to inflate the lifejacket. 

Automatic: Mark 5i. This inflation system works on the 'paper pellet' system (a coil of paper inside the unit dissolves when submerged in water, triggering the inflation system within 3 seconds of getting wet). The Mark 5i firing head requires a 38g CO2 cylinder and is widely available at most chandleries. 

Inshore Lifejacket: 

Manual: the wearer must manually pull the handle to inflate the lifejacket. 

Automatic: Mark 5i. Please see description above about the Mark5i unit functionality. 

Coastal Lifejacket:

Manual: the wearer must manually pull the handle to inflate the lifejacket. 

Automatic: Mark 5i. Please see description above about the Mark5i unit functionality. 

Offshore Lifejacket and Ocean Lifejacket: 

Manual: the wearer must manually pull the handle to inflate the lifejacket. 

Automatic:

Option 1: ProSensor Elite: The Pro-sensor Elite firing head works using a water activated system. A compressed paper capsule is contained within the firing head. When it becomes wet it dissolves and releases a spring which fires the CO2 cylinder and inflates your lifejacket.

The firing head is designed so that water must travel upwards inside the unit to dissolve the paper pellet. It is then also protected by the lifejacket cover. This means that spray and rain will not cause accidental inflation.

Option 2: Hammar: The Hammar inflation system works by using water pressure to release a spring and inflate the lifejacket. Unlike the Pro-Sensor described above, the Hammar firing head requires immersion in water to activate - the cap needs to be approximately 10cm underwater to achieve enough water pressure to activate the unit. 

The Hammar system is intended for use in more extreme sailing conditions and is therefore often favored by sailors doing offshore sailing as it is less likely to inflate accidentally in weather when there is a lot of water and spray washing over the deck. 

Do you make children's inflatable lifejackets? 

Sadly not! We get this request a lot. Unfortunately we need specific ISO approvals to be able to offer childrens lifejackets we can't make a custom one for you. We are working on this though, so please watch this space!

Do you make lifejackets for dogs? 

Unfortunately we cannot make dog lifejackets. 

Can you ship to me in my country? 

Yes we can! Please see our Shipping page here for full details.

Can I fly with my TeamO Lifejacket? 

Yes you can! Please see our Flying Guide for full details.

Nice quality.

Most comfortable

Great looking and the quality is superb. I love the fact that the collar sits back off my neck so it’s not weighing down and really unnoticeable when wearing it. We purchased ours for an offshore race which was rather challenging with high wind speeds. This product fitted well and never irritated me like others have done with being too heavy on the neck.

Comfortable and Reassuring PFD

I have two of these now and love them! The comfort and quality are great. The features within this life jacket are very reassuring and I highly recommend them to anyone who ventures out to sea. My wife also thinks the colors and design are great.

Safety

Appears to be a quality inflatable harness. I have worn it on two short open water races for 36 and 48 hrs that involved night portions. Very comfortable. I put my AIS beacon inside attached to the manual inflation tube with no problem.

Great Service

Really slick service and quality product
