Self-baling, self-righting lifeboats are not new, however they are designed for stability
and surviving rough water rather than speed. Their slow speed would be of doubtful
utility as pickets. However perhaps a hybrid hull design that flattened the bottom out
towards the stern would allow increased speed without completely compromising
seakeeping. Something not unlike the hull design of an S-Boat in fact.

Here is a pdf on the USCG 36' boay which is of the period and could form the
basis of a picket boat concept.

Sometimes neither do 45,000 ton battleships or 30,000 ton carriers...

The North Atlantic really doesn't like ships, does it?  :o

I showed that to my missus and she felt a little bit seasick just watching it. Mind you, the Belfast ferry's normally more than enough to set her off.

You'd want to time your landings and take-offs very carefully, now wouldn't you?  Admittedly, if it was a Swordfish, all you'd need to do would be to turn into the wind and have the deck crew let go and and it'd take off and fall behind the carrier as it climbed.  ;)

Landing on, backwards, from the bow might be interesting, too. ;D

The FAA's first VTOL aircraft perhaps?  ;D

With all this talk about launching and recovering MTBs/MGBs/MASs, why not use an LSD?  Open the well deck doors, and out they motor.

I read( somewhere, somewhen)  about a carrier launching a Fairey Applecore sorry, Albacore in a really high wind. The assembled hordes holding it down all let go at the same moment, and it rose into the air and drifted slowly backwardsrelative to the carrier.

How quick would they need to be though? Convoy speeds could be as low at 7 knots and even the purpose-built escorts sometimes had top speeds of under 20 knots. Submarine speeds were less than 20 knots on the surface and less than 7 knots submerged. Normal MTBs had speeds in the 40-50 knot range, so their design could be compromised considerably in the name of seakeeping rather than speed if they only needed to do say, 25 knots.

Having seen a Storch  recently at Duxford they can literally hover if they get the wind just right. I believe Fiesler were down to make one of the Torpedo bombers  the Fi167 if their had ever been a Kriegsmarine Air Arm.

"After two prototypes (Fi 167 V1 and V2), twelve pre-production models (Fi 167 A-0) were built. These had only slight modifications from the prototypes. The aircraft exceeded by far all requirements, had excellent handling capabilities and could carry about twice the required weapons payload. Like the company's better known Fieseler Fi 156 Storch, the Fi 167 had surprising slow-speed capabilities; the plane would be able to land almost vertically on a moving aircraft carrier

As for the LSD

A full size one would probably have been needed elsewhere however there could have been ELSD or Escort Landing Ship Docks or maybe just ESD's or maybe one of the Heavy Lift ships on the Russian run could have  had a couple of boats stowed on deck and lowered when necessary although I wouldnt have wanted to been on a MTB on the Artic Run.

When I see clips like that it really makes me realise what my dad and his crewmates went through on a Corvete.

Dad said that on occasions the deck crew and any one lurking in the gun pits with nothing to do would be called upon to grab a Swordfish that was having trouble landing in bad weather and pull it on deck  :banghead:

In other words, the patrol boat is not so much a soldier as a security guard with a torch, a radio and a whistle.

That's the type of thing I was on about. Nice simile  :thumbsup:

There's an excellent Canadian TV movie about the wartime experiences of a corvette crew: really brings it home to you what miserable little things they were, and how terrifyingly scarce material was (did it's delivery voyage with two depth charges and a grey-painted telegraph pole instead of a 4" gun... :blink:). Can't remember what it's called but doubtless some folk around here will leap in... ;)

Must re-read THREE CORVETTES   and   THE CRUEL SEA. Nicholas Monserrat  wrote from experience of commanding them.
