You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 35.175.0.0/16 has been blocked (disabled) by ‪JJMC89‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 05:20, 2 March 2025.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

The '''Type Two HSL''' was a 63 ft [[high-speed launch]] craft made by [[British Power Boat Company]] (BPBC). The craft were used during the [[Second World War]] for [[air-sea rescue]] operations to save [[Allies of World War II|Allied]] aircrew from the sea. The Type Two superseded the [[64 ft HSL]], and was itself replaced by the [[Type Three 68 ft HSL|Type Three 68 ft "Hants and Dorset"]] also built by the BPBC. The Type Two (aka Type 2) was nicknamed the "Whaleback" due to the distinctive curve to its deck and humped cabin.<ref>((cite book |last1=Diane Canwell and Jon Sutherland |title=RAF Air Sea Rescue 1918–1986 |date=2013 |publisher=Pen & Sword Aviation |isbn=9781848843035 |page=41 |url=https://books.google.com/books?id=uCPOAwAAQBAJ&pg=PA41))</ref>

==History==
[[File:RAF HSL 130 rescueing Halifax crew c1942.jpg|thumb|left|HSL 130 picking up an RAF [[Handley Page Halifax|Halifax]] crew off the Isle of Wight, 1942]]

The Type Two was designed in 1937 by George Selman, Chief Designer and Naval Architect of the [[British Power Boat Company]], which was founded by [[Hubert Scott-Paine]] at [[Hythe, Hampshire|Hythe]]. Scott-Paine had previously owned the [[Supermarine|Supermarine Aviation Company]], later builders of the [[Supermarine Spitfire]] and several [[flying boat]] types.

A low-set cabin contained the wheel-house, chart room and a sickbay. For defence against enemy aircraft, on top of the cabin were two aircraft-style turrets made by [[Armstrong-Whitworth]] initially with a single .303 in [[Vickers K|Vickers K gun]] or [[Lewis gun]] (later improved to paired guns of the same calibre). The mahogany<ref name="BMPT" /> hull was of the [[chine (boating)|hard chine]], [[Planing (boat)|planing]] type.

==Usage==
During the Second World War, the retrieval of pilots and aircrew who had been shot down over, or who had had to ditch in, the sea around the British Isles was the responsibility of the [[Royal Air Force Marine Branch]], (motto: "The sea shall not have them"). Rescue of downed aircrew was coordinated using RAF aircraft, aircraft operated by [[Coastal Command]] and the [[Royal Navy]] and rescue launches operated by the RAF Marine Branch and the Royal Navy.

The Type Two was supplied to RAF marine craft units from the middle of 1940. In total, 69 craft were manufactured between 1940 and 1942.

After World War II, a number of the Type Two craft were transferred to the Royal Navy and a small number were given to the Italian Air Force. The vast majority of the Type Two craft belonging to the Admiralty were subsequently stored and later sold off as houseboats. None are currently owned by any museum or trusts.

==Variants==
Following their performance during the  [[Dieppe raid]] in August 1942, the Type Two was modified. Extra armament was fitted&nbsp;– paired .303 in machine guns mounted either side of the wheel-house and a single [[Oerlikon 20 mm cannon|20 mm Oerlikon]] on the (strengthened) rear deck. Protection was improved by adding anti-shrapnel padding around the forward cabin area.
