Does Anyone Know What This Is?

Does anyone know what this object is? And how it works? The plastic object in the holder on front of (next to) the life raft. It's been hanging there for three years, came with the boat, but I have no idea what it is.... I assume it's some sort of lifesaving, floating marker buoy.

It is an inflatable Jonbuoy.

Re: Does Anyone Know What This Is?

Thanks,

Does it need to be tested or charged?

Re: Does Anyone Know What This Is?

I have never owned one so I am not sure.

I assume it has an inflation mechanism similar to the automatic life vests. As you are aware these do need periodic replacment of both the CO2 canister and the water detection/auto firing mechanism.

I would take it out and have a look, but it might automically inflate as the canister opens. If it has a manual inflation like a lifejacket the first stage is to blow it up by mouth and check it holds air for a couple of days. If it passes this test see if a reaming kit is available.


Then try throwing it in the water and doing a MOB drill. Nothing like practice and learning how to use saftey equipment.

If it was me I would also tie it to a big fender. A Jonbuoy is much easier to see than a fender, but fenders at least give some flotation to the MOB victim and they provide a backup marker if the inflation mechanism fails which is always a slight risk with a product like this even when new.

Re: Does Anyone Know What This Is?

Hi Ken

I have one of these, and replace the firing mechanism every 3 years, and give it a good inspection annually.
Mine came with the boat, dont think the PO had looked at for some time as the CO2 canister was very badly corroded.

Just leave it alone and give it to the next owner when you replace the mono with a multi.

OK. Here's the plan, we'll fire it off in two weeks at our first anchorage.

Plan to hook it to a fender in case it sinks, wouldn't that be ironic....

When the Isara 50 or the Sunreef 58 is within striking distance in the used market. Meanwhile, we're just going to be satisfied with our Oyster 53 with some prosciutto on board.

BTW: Are you getting any closer to a Cat purchase?

Relocated the Westerly to Sussex. (South East coast). Stuck here. Up to nuts in work and issues for the time being. Not been looking for a while to be honest. Other things have priority. ..... I'd only goof off and not get things done if I had one in the dock....

Glad it is inflatable. I thought an inflatable dolly for long night in the raft.

If you do, you'll need a rearm kit, which seems to be available only in the UK.

I actually just posted an inquiry yesterday looking for somewhere in the USA to buy a Jonbuoy Danbuoy. Anyone sell Jonbuoy Danbuoy in the USA?
