MBYJan09 WNS scenario

What Now Skip – ReadmeFirst please.
The primary aim of the What Now Skip series is to encourage readers to share their expertise and experience with others. We will publish a monthly ‘tricky situation’ scenario. We would like to know how you would deal with it. In return, we will publish our solution in the magazine the following month. Should you wish to comment on that – and we’re sure you often will - please feel free to do so in this forum!
In some cases the situation will be quite specific. In others, it will be less clear cut, involving some ‘If A then B, but if C then D’ thinking – which is how real life situations evolve. For example: ‘If the fire extinguisher puts out the fire, remain on board. If not, abandon ship’.
Safety and seamanship aspects such as crew briefing, monitoring the weather and general situational awareness are paramount even if the primary problem is a technical one.
Write as much or as little as you like. If pushed for time a chronological list of your thoughts and subsequent actions will do fine. E.g: 1. Stop boat. 2. Brief crew. 5. Recover bimini from over the side. 6. Continue to destination.
If you have a scenario in mind that you think would test the mettle of your fellow readers, please email it to the editor. We will use it if at all possible.

January 09 Scenario
You are cruising on a late summer’s afternoon along the picturesque rocky coastline with many small bays and coves which lies immediately to the west of your home marina. The wind is directly onshore, force three to four and the tide is in mid flood.
Your boat is a 38ft sports cruiser of late 1990s vintage with twin diesel sterndrives and an electric bowthruster. On board are you, your partner and another boating couple who are old friends. All are competent boaters and the other man is an athlete and strong swimmer.
Apart from the usual equipment your boat has a 3m inflatable tender – inflated and secured on its side on the bathing platform with snap davits. Unfortunately, one of the aluminium oars got broken recently and you haven’t had time to replace it. In the lazarette is a 4-man liferaft, two adult buoyancy aids and a strong, 70ft polypropylene towing warp.
Your wife draws your attention to some people waving frantically from one of the coves and your binoculars show this to be two children of around ten, marooned on a flat-topped rock about 100m from the sandy beach at the foot of a cliff. At this stage of the tide the footpath is impassable. The rock is nearly awash and unless something is done very shortly they will shortly be swept off into the surf. No one else is in sight.
Local knowledge tells you that although there is a clear passage about 25m wide all the way in, there are nasty rocks either side and at this stage of the tide, the closest you could safely approach the rock is 30m. What Now Skip?
 
Well, first, you dont say whether there is a calculator aboard, or whether the crew are particularly good at sums.

I'll guess that the 70ft tow rope is about 20 metres??

So you anchor the boat to seaward of the rock and drift back till 30 meters away,then add a mooring warp to the tow line, stick hercules in the dinghy, where he drifts and paddles to the rock.

Undoubtably this boat has no mooring warps, so superman swims the last 10 yards feet or metres or maybe drags the rock a bit closer. /forums/images/graemlins/grin.gif

Fortunately, the 5hp outboard was fixed on a recent MBM cruise, so having alerted the coastguard and telling them what you're about to do, put swmbo on the helm of the big boat, having pointed out to her where the rocky bits are. Cut the engines when a safe distance off, deploy the tender with outboard (taking the buoyancy aids and the towline). Check that swmbo has restarted engines and is happy to hold station against the wind/tide.

Approach in the tender. Ask the kids if they are strong swimmers. See if it's possible for the kids to jump safely into the water. If no, can they climb along a bit and find somewhere else to perch until help arrives? Then lurk around in the tender until either they are washed off (in which case haul them in anyway), or are rescued by the professionals. If yes, get them to jump in and swim to you one at a time as you wait a little way down-tide.

Return to big boat, get swmbo to kill engines before re-boarding.

1. Alert the coastguard
2. You cannot risk taking your boat inshore as described, so no point in creating another casualty.
3. Motor into the tide and stay a safe distance offshore
4. Lower the tender and attach it to the 70ft warp, and enough other spare/mooring warps to allow it to reach the shore
5. If asked by the coastguard, get your strong swimmer with the buoyancy aids (anything is better than nothing) into the tender, and let the wind carry it inshore to the rock.
6. Hover using engines and bowthruster while matey picks up the kids, then pull them back to the boat
7. Transfer the casualties to the ILB when it arrives.
 
First off, send out a Mayday on the VHF as there is clear grave and imminent danger to persons. Doubtless the coastguard will reply and you can explain the situation. At this point you have to make an assessment of whether the 2 kids are going to be swept away before the RNLI arrive. If your assessment is that they will, I think you have a duty to attempt a rescue
The closest distance you can approach is 30m so I would approach the coast at minimum speed and station the boat about 40m off and uptide of the casualties. Instruct one of your competent boater crew to point the boat into wind and tide and use engines and thruster to maintain position which should not be difficult. You have a 70ft (21m) towing rope on board. It is highly likely that you also have some mooring lines. Use those lines to make up about 50m of rope. You then have to decide whether to launch the tender or the liferaft. I would launch the tender because it's more manouvreable, even with one oar. Tie the 50m rope to it and instruct your 'superman' to get in it with the buoyancy aid on and take the other buoyancy aid with him (plus any lifebuoys you have on board). Tie the other end of the rope to your boat
Tide and onshore wind plus the efforts of superman with one oar should drift the tender to the casualties. Final positioning could be aided by moving the boat but make 100% sure you don't foul the 50m rope. If superman can get close enough the kids can be manhandled into the tender. If he can't at least he can throw the spare buoyancy aid and any lifebuoys towards the kids in the hope they can geab them and stay afloat until the lifeboat arrives
If the kids manage to get into the tender then the tender can be pulled back to the boat using the rope and the anchor windlass if it proves too heavy to pull by hand
A few months later you get an MBE from the Queen and a prosecution by the MCA for endangering the lives of your crew

Oh how true /forums/images/graemlins/laugh.gif
 
i agree with this.

I would praps tie a fender to the end of the (presumablty floating) poly rope or somewhere along that lot for extra viz of what's going on and getting more windage on rope/dink combo

Also consider (depends on actual conditions and topology of seabed) floating superman off the bow - 30metres is scarily close and we are all knackered if the props go crunch. Mebbe also consider protection for superman eg gloves/shoes for when he gets close to the rox.

Most important of course is to ask the kids if they have got a spare oar.
 
Ooo! You must have all been waiting with bated breath and fingers poised over keyboards for this to be posted. How nice to be so popular. /forums/images/graemlins/grin.gif

Anyway, thanks for the excellent replies so far - which go to show that one man's acceptable risk in another's No Go. IMHO both are perfectly reasonable answers.

Cheers

I've just measured this and found it be err, 70ft.

[/ QUOTE ]Please highlight the post where anyone suggested taking the 38 footer in. So far everyone has suggested holding off and going in by letting the tender drift in (apart from S28, who used the conveniently repaired outboard. Can't see anyone deciding someone's no-go is an acceptable risk...
 
As I understood, neale suggested to standby - period, whilst others suggested to give the rescue a try one way or another. Dunno if that's exactly what TJ meant, though....
 
70 feet of rope =21.336 meters.

Closest you can get is 30 metres so that leaves 8.664 short.

The tender tied on at the end is 3 meters so thats 5.664 left.

The Liferaft is lets say another 3 meters so that would be 2.664

Of so there's no rope to tie the dinghy to the lifraft so this is where the strong swimmer would hold onto the tender in his left hand and the liferaft in his right thus spanning another 1.4 metres.

This leaves a gap of 1.2 which two 10 year olds would be capable of jumping. However, just in case they're scared stick one of the women in the liferaft with the oar that isn't broken. Get her to make a bridge to land with this.

Easy.
 
"Apart from the usual equipment" ? 2 lifejackets for 4 adults, polypropylene rope for towing, dinghy with no means of propulsion? Sounds like a right MAM (manky auld mobo). Probably no working vhf or mobile either.

Ah well - unlay the polypropylene rope and attach to dinghy, the 3 strands will give you about 60m. Strong man stays on board to pull it back, one of the wimmin goes in the dinghy with the lifejackets, some fenders (what, no fenders?) and the teaspoon paddle (tied on please) and guides the boat to and onto the flat rock to pick up kids. Skipper tries to hold boat directly up wind on engines and thruster.
What's the English equivalent of Disclosure Scotland - you'll need it before letting the kids on board!
 
So why the rush to get them all abck to the boat? I'd get as close as safely possible, put the athlete in the dinghy and send him to the rock. It's pretty easy to row(?) the dinghy from the bow with just one oar, done it many times, especially with the wind behind you. Pick up all 4 peeps, should fit into a 3m inflatable and them take them to the sandy beach which is only 100m away. In the meantime as skipper you've contacted the coastguard with a mayday which hopefully will soon be cancelled once everyone is ashore. the 4 stranded folks will now be able to make their own way back to their car/hotel/b&b or whatever and your athlete should be able to paddle himself back to your boat.

Then crack open a few beers and set off to your marina feeling pretty satisfied with a good hours rescueing.
