300m is a good old stretch even if you were in your spedos and in flat calm. The boat will move with wind far more than you would and probably same with tide. So unless you are upwind and up tide and its blowing towards you you are on a loosing battle.

A decent swimmer will probably take 30minutes in a wet-suit open water swim to do a mile, in relatively calm waters. So they are only swimmeing at 2mile an hour. If the boat is drifting at 2MPH or more they'd never catch it. In a dry suit with a life jacket there is no way you could swim that fast, I doubt you'd even make half that pace far more likely 1/4 of it, so 800m an hour. So if the boat was at anchor and you had no wind or tide to fight it would take you 22minutes to get there and you still need to get back in the boat!

If the boat was drifting at even 1/2MPH more than he was due to wind or tide effects in 20 minutes It'd get another 400m away which takes another 11 minutes to swim, by which time its drifted another 200m takes another 6minutes, drifts another 100m, takes another 3 minutes, drifts another 50m etc... On that scenario he'd eventually catch it after something like 45 minutes of swimming. BUT how many of us can swim for 45minutes flat out in a dry suit in open water with a life jacket on without needing to stop for 5 minutes for a breather... meanwhile the boat drifts further away.

20m chasing a sailing dinghy after a capsize in a drysuit in non-tidal water with a bouyancy aid on rather than 150N+ of lifejacket and I still take a breather before climbing on the board...

I've always thought people to be too quick to dismiss clipping a lanyard from the boat to your LJ.
Despite having all the right gear, dry suit, LJ, PLB, KC etc, he was still quite lucky to get out of this one.

Sure it is, but despite being quite tech savy I just can't for the life of me figure out how to find your specific tracker... or anyone's that isn't listed on their events page.

hello all...
as am sure you would like details...here goes.
I arrived Neyland at 11 am just in time to see everyone leaving. I still had to fuel the boat and stow kit so was taking my time. No intention to catch people up, and was going to take my time crossing to conserve fuel.
Set off at 2 pm, after launching, parking car and trailer etc .
Out of the sound I hit the overfalls Paul Glaetzal describes.
Lumpy confused chop, not too dissimilar to conditions off Tynemouth in the North Sea, where I usually boat. It would smooth out, get lumpy again, smooth out etc etc.
I was transiting at around 14 to 28 knots depending on conditions.
We have all been in seas like it ...you have to look 3 crests ahead plot your route etc etc. Had hit a smoother section and got the boat back up to 24 knots from 17.
I had just checked the SOG on the plotter about 20 seconds before coming out of the boat. The crest that caught me out looked no different to those I had been crssing on the journey, except this had the mother of all holes on the other side.
The boat came down off the crest tipped to starboard and just fell, and I fell faster.
The jocky seat wrenched out of the floor with the force. It was held in with 6 stainless dome head M8's. The seat stayed in the boat. I hit shoulder first. Kill cord worked instantly. One of the first things I noticed in the water was it wrapped tightly round my leg, so I started looking for the boat. After the disorientation and initial water swallowing, I pulled the inflator on my jacket. One of the first things my hand touched was the back plate from my Entel Vhf which was not attched to the rest of the unit. The hand held was attached to the right shoulder of the lifejack in the velcro and webbing nest Baltic provide for it, aerial looped through a webbing pocket. It must have disintegrated when I hit the water as apart from that initial piece of plastic from the unit my hand touched I never saw any more bits or parts of it. My PLB - its a GME unit - was attached in to the webbing nest built into the harness of my jacket, I felt for it and it was there. First priority was firing it to let someone know what had happened. I looked at the RIB it seemd to be around 100 metres away from me in the water, but in reality I knew that distance would be further. I also was not going to be able to get to it with lifejacket inflated, just trying to get upright I was worried I would tip onto my face. My Gecko was still attached, I wore it throughout the rescue. Am sure it absorbed some of that initial contact with the water, and as time dragged on it kept my head warm. I firred up the PLB and lay back with it on my chest. It started beeping and flashing. Looked at my watch about 10 minutes after I had gone in, it was 3.45pm. I knew they take up to 30 mins to get a pass from a sat, but was concerned that the impact with the water had possibly damaged the unit. at 4.10pm the unit made a very short set of extended beeps, easy to miss with my Gecko on. This on reflection was the sound of the satellite transmit working (it was a GPS equipped unit) I had been in the water approx 30 mins at that point. The RIB would sometimes come closer and then 2 mins later would seem much further away. After an hour in the water , the temptation to try to get to the boat was massive. I knew it would mean deflating the bladders on the jacket, but I didnt want to let go of the PLB and swimming in the dry suit, jacket, gecko combo is nigh impossible. I floated around in circles, crossed my feet pulled in my arms to my sides. The inflated chambers of the jacket blocked a lot of peripheral view. My view was like a gun barrel down the sides of the chambers, so to look for anything I had to paddle myself through 360 degrees. I saw a yacht around maybe 500 metres off, but couldnt attract its attention. Looked at my watch - it was 5.00 pm. In the water around 1 hr 15 minutes. Water was cold but with really warm pockets and currents flowing through it, sun was shining, the swell was running at around 2 or 3 feet I would estimate. I looked at the watch again at 5.15 pm. Knew it was around one and half hours since I had gone in. With no way of knowing if the PLB signal had been received, I was beginning to get just a little bit concerned. I could sometimes see the Echomax on the A frame of the RIB over the swells, maybe 250 to 300 metres away. at 5.20 pm and just starting to feel a little chill, and getting cramps in my legs, I let some of the air out of my jacket and contemplated getting myself someohow to the RIB. I saw the funnel of the Irish Ferries ship then, maybe 500 to 800 metres behind my rib, and about a minute later heard the Seaking from Chivenor. They positioned themseves round 20 metres off the water, hovering facing me. I made a signal to try to tell them just me (one) and pointed at myself as I expect they were looking for any additonal people in the water. They put the diver in, and he hooked me up and 15 secs later I was in the helo, looking down at all the pax on the Irish ferries boat enjoying the view. I asked the winchman to go back down to my RIB as soon as I was on the helo, they asked about injuries how I felt...I said I was fine, I have a massive dent in my pride but otherwise fine. They conferred with MHCG and then winched me back into my boat.
There was a Dive Boat on scene then and he asked about intentions, I was contemplating keeping going to Kilmore quay until I saw the state of my seat, so I agreed to wait for St Davids lifeboat ad followed that into Milford Haven, where the Angle lifeboat met me and went with me to Neyland. Apart from the seat, the Rib is fine. Apart from a big bruise on my shoulder, I am fine.
I was so cross with myself for the ejection. As I was going over in that split second, it was running through my mind, how am I going to explain this then !
I was disappointed about the VHF but in the circumstances of the impact, makes sense I guess. I woud like PLB/EPIRB manufacturs to install some way of bouncing back a signal to a beacon - some tell tale fool proof way / big red light or something, that is activated on your beacon when your distress signal is received. Another 10 or 15 minutes and I may have attempted to get back to the RIB with a poor result.
Big thanks to the Chivenor crew who I think were a little "surprised" that I wanted to get back on the RIB when they picked me up, the St Davids and Angle crews for the escort and chat, and the Coastguard at Neyland for sorting a berth at the marina (and some fish and chips - hungry business this rescue stuff).
and yes I am lucky - and yes I love my boating kit.

You are one lucky mofo
Glad you are still here to tell the tale, thats certainly one for the grandkids

Any camera crew on the helo, would be great to see it all on the next season of Seaside Rescue

Any thoughts on being clipped on to the boat?

being clipped to the boat ...hmmm
as I fell out sideways... I would no doubt have made contact with the hull I think. Hard to say and I am not volunteering to test that.

This morning I am asking myself - was I going to fast, quite possibly for the unpredictable conditions, but I do feel this was freak hole/wave combo. To go slow enough for that kind of sea to be nanny safe I would be at displacement speed. This came out of an otherwise smoother looking section of sea.

Presume you were on a manual jacket rather than it failing to pop.

So was it clipped onto it on the outside? I gave up clipping on handhelds as the clips break far to ften if you fall against them (I think I fall over too much!!). Attach with a caribener now but I worry that the tiny little lanyard eye on the radio would just break.

I was under the possibly mistaken impression that 406MHz between the 70's of latitude had geostationary cover so you'd expect almost instant transmission. 60 second delay inbuilt in set to avoid false alarms. Then time for a satellite possition lock then transmit was my understanding.
I thought the LEO sats were not geostationary and were able to position the transmitter to within a couple of miles or so but had a delay as they needed to move to do the positioning.

That sounds to me like it took 30mins to get a sat fix. Thats very slow.

Crotch strap or not?

Shame the VHF was destroyed. Do you carry personal flares? I ask because there are a good number of people who don't have a PLB on here who would take the view the VHF is their saviour but wondering what their options are if the VHF is obliterated...

Hi...
LJ says Auto.. but it didnt fire. It has 75n of foam buoyancy plus air in my dry suit.
Yes crotch straps, correctly fitted.
As for the exact functioning of sateliites and PLB's - will bow to your superior knowledge. It may have taken its time, but it did work.
VHF was strapped in tight, but I think it was main point of contact with water when ejected.
Personal flares would have prob helped with the yacht passing, but whether they would also have survived the impact with the water, which had the effect of stripping things attached to my LJ/person is debatable.
