The Ship Model Forum

Can any one point me to a picture of the front of a closed bridge Hog Islander?

Thanks
Will

Thank you very much.

The steam winches from a liberty ship should be close. The liberty ship design came from a 1930's British "tramp" design. I built APA-6 Heywood (a WWI passenger/cargo design) and bought a Trumpeter 1/350 liberty ship just for parts (winches, vents, anchors, etc.).

Any plans/drawings for deck/cargo winches suitable for Hog Islander?

Ironic humour. Now when I search for an answer to my question, google lists me several times. Apparently I have become a google referent. Hogs were generally done their "careers" by 1947-48. The Hog Islander was somewhere between 380 to 401 feet OAL although it could be Lpp. 54 feet is the general consensus on Beam and draft is apparently somewhere between 24 to 27.5 feet ( plus the usual fresh water salt water summer winter allowances). Considering it was wartime and skilled labour was in short supply, and the hulls were wanted quickly: 1/ the hulls were riveted Lap strake (British = clinker) as flush plating was more difficult, heavier, costlier and slower. 2/ plating starts at the garboard strake and proceeds up and forward to the bow. 3/ butts were probably backed by a butt plate and the seams were done with the traditional steel plate caulking ( i.e. pneumatic caulking chisel to upset the steel).

All the hog islanders were built at the Hog Island shipyard. No other yard built them. I don't remember reading anything describing the plates being lapped or not.

Apparently the definitive answer is the hull plates are overlapped on both the butt and the seam and lapstrakes used in behind. Neither frames nor plates were joggled. Dissenting opinions?

Finally have learnt what to name "some" things.
The joint between one hull plates side edge and the side edge of the adjacent hull plate is called the "butt" in British shipyard terminology.
The joint between the bottom edge of a hull plate and the top edge of the hull plate immediately below is called the "seam"
Is/was American shipyard terminology different with regard to these joints?
With respect to the hull plating on a Hog Islander were the seams joggled?
Since my model is in 1/48th scale and the plating method affects its appearance I am trying to find the relevant information so I can model it correctly and such information is challenging to find.
Is there a particular term applied to the hull plating that involves IN Strakes and OUT Strakes ( like the Titanics hull plating "style").Did the Hogs use this style? From the photos available my guess is they didn't and I lean towards the joggled plates for the seams. However, I have seen photos of a Hog Islander presentation model and the joints there are very evident as IN and OUT Strakes joints!

Thanks Laurent. I appreciate your help.

Hi Will.

Question1: depends on which builder has built the ship. Clinker riveting was most of the time only used with hydraulic riveting machines, which were heavy and cumbersome. My guess is that those hog islanders, being built in "back yard shipyards", would have been hand riveted, so the IN & OUT plating option would be the most obvious. Forget about butt joining on a frame, there must have been butt seams or the butt ends couls be riveted together.

Question 2: the option C is the only option I have ever heard of.

Okay, first up I'm an Airlubber so excuse my newbie questions. I am attempting to model a 1930's hog islander hauling sugar between Cuba and the united States. My question relates to hull plating. On other fora I have received several conflicting replies as to how the plates were joined.
1/ Suggests it was clinker style with the bottom edge on one plate overlapping the top edge of the next plate by several cm and hot rivetted through the land. Lateral edges are butt joined on the frame.
2/ all plate edges are butt joined and "caulked".
Caulking could be one of three diverse methods (apparently designed to create long discussions for the airlubber).
a/ A red lead paint/paste bed into which the hull plate is laid then hot riveted.
b/ An injected red lead based paste
c/ A metal caulking tool is used to upset the metal at the butt joined plate edges . The tool is a large broad blunt chisel type tool resembling what we here call a cold chisel.Initially done by hand and later with pnuematic tools.
HELP! Which one will do for my Hog Islander?

From terribly blurry drawing. It "seems" to be that the main cargo booms capacity on a Hog Islander is 8 Tons. Hoping someone on this forum "might" know.

I forgot to mention there are 2 plan sets available from the National Archives:
USS Sirius & USS Vega.

Hi,

Hog Islander Type A(Capella Class)

Length (oa): 401�
Beam: 54�
Draft (max): 24�

Source: Division of Naval Intelligence 1 September 1945

Hope this helps.

Thank you.
Doing a rough measure the 401 as LOA fits the 390 Lpp on the drawings
Draft is given as 24.5 ft or 27.5 ft or 29.5 ft
The one measure "they" almost agree on is beam/breadth as 54ft or 54ft 1in
Thanks
Will

Hi Will -

Not to make things worse, but Mark H. Goldberg's "The Hog Islanders: The story of 122 American ships" has a rough drawing indicating the length at 401'-0" but the text (pg. 35) indicates "The ships were 410 feet long overall, 390 feet between perpendiculars, 46 feet in beam and 27.5 feet in depth"

I suspect the 410 listed is in error, and should read 401, but in any case at least the LBP at 390' corresponds to McKellars' figure.

Hope this helps.

I have undimensioned drawings from several sources and am trying to cobble them together to build a Hog Island Type A , EFC 1022 cargo vessel.
The problem.
From different sources I have three different lengths given for this hull.
From navsource, shipscribe and Wikipedia plus the BFM model 401ft.
From Norm McKellars site 390ft
From usmm 380ft.
My (limited) understanding is the Hog Islander Type B hulls (Harriman), EFC 1025, were longer and troop carriers. That hull length is given as 401ft. But to add to the confusion Wikipedia lists the SS Liberty Glo as a Type B hull at 390ft and the USS Capella as a Type A at 401ft! I had hoped the discrepencies were because of the differences between LOA and LBP, Lpp and they just weren't telling me which one they were using. Nope.
My question.
By sheer dint of numbers am I safest to ( scale my drawings) go with 401ft or over time have the sources inadvertently mixd 1025 hull dimensions in with 1022 and in fact 1022 hulls are 390ft?

Confused cheers
Will
