Oh, I had a Beaufort
6 person raft just like that.
If it's never been serviced, best case, everything that has an expiration date inside the raft will need to be replaced. So the batteries, flares, food
packs, CO2 cylinder, will probably add up to something around $1k with the repacking. You can call a service
place and see if they'll give you a guesstimate, each raft and brand has a different set of parts
But that raft looks pretty beat up, so I'd be worried about more entropy and chaos than just things expired. I've had two liferafts totaled by repacking places, and they both looked better than that from the outside.
Also, a common way to sell long expired liferaft
is to have a service
facility take a look. Since it could be worth nothing. So I'd be wary of ebay since you couldn't arrange that for this raft. Anyways, in other cases, you can have the seller meet you at a repacking place, have them take a peak inside, see if it's a disaster or not and give you an idea of about how much it'd cost to fix. There's a log sheet inside that will tell them when things are due to be replaced, and etc. Some places are more uptight and won't 'break the seals' unless they are doing a full repack -- maybe if that's your local situation you can negotiate that you'll pay X - whatever the quote for the service is.
