Guys,
I think what would be needed would be to straighthen the sides of the hull going aft. A DE slims down quite a bit from the waist to the stern; an AVP on the other hand has a pretty constant width aft to just forward of the screws. So the side pieces would have to thicken the hull running aft.
Additionally, I was thinking about it and, if you're going to do a water-line you're going to have to add some material to the lower hull to raise it up out of the water some more. The AVP sits higher out of the water than does a DE.
I'm not sure if a Tamiya Fletcher bridge structure would work because I think it's not the same diameter as the AVP; if I have time I'll pull some of my plans and see if I can verify for you.

Good modeling,
Bruce

Welcome Jepot,

Saw your posting and was thinking of the challenge of reproducing one of these ships in 1/700. I think that a Bulkley class DE hull is going to be your best chance. There is a 5ft. difference between the classes in length and overall lenght (5ft = .087"). You could glue some .040" strips to the sides and blend in the extra width. I think your biggest challange is going to be the stern; they are entirely different. If you look on Navsource for pictures of the AVPs you'll note that the sterns are more squared off than the DEs. There are probably several ways to handle this depending on how much pain you want to endure and how accurate. The other difference to note is that the AVPs did not have a sharp deck edge similar to the DEs; instead about 8ft from the bow a round over starts that carries to within about 20ft of the stern. This is easily modeled by just sanding the round on the edge.

Anyway, good luck; look forward to see your project and progress.

best,

Bruce

wow, thanks for the advice; yes, i have an extrs Buckley in my stash ( though i intend to make it an APD - thats ANOTHER story...) but yes,a s i had said, the shape of the hull would be the killer here - but better that than cutting up my fletcher; the reason why i thought of my fletcher was the similarity of the bridge superstructure to a barnegat at first look; along with some stuff i can kitbash from the fletcher; now if only the stuff i intend to get from the fletcher fits on the buckley, and most of all if i have the time....

You all have got me side-tracked now!

With Jepot's suggestion of a 1/700 Barnegat and Bruce's suggestion of a Buckley class DE hull, I just might look into bashing my own.

Jepot, are you thinking full hull or waterline model of the Andres Bonifacio?

A waterline model would be easier, to me. A Buckley hull's steeper bow angle could be shaved down and the stern could be rounded off.

Skywave makes (made) a 1/700 waterline Buckley kit.

There is a review of the kit at http://www.modelwarships.com/reviews/ships/de/de-51/de-51-700.html

Hmmmm!


nuke,

id rather do a waterline - thats all i have anc could spare for now amongst the hulls i have.

considering the conficguration of the PF7, specially the radar suite she had, i was really thinking of doing two projects of a similar vein at the same time- a DER and the AVP; both had ( i think ) the SPS 29 radars along with a tripod mast that ahs to be scratchbuilt so hopefully hitting two birds with one stone there... the first tripod mast i got to buidl in 700 scale was with another DE, the PS76 RPS Datu Kalantiaw, a Cannon class dE i posted in the Cannon class fans thread.

anyway, if i do get the plans and time ( the drive and the kits are there,,,) to start this projet- as i said its a holy grail project for me,....

:woo_hoo: yeah Bruce- thanks for this pretty important note! as i said thought the brdige of the tamiya fletcher was same as the AVPs...grossly as it seems, ONLY... hoping for the plans and comparisons....

I went back and checked my plan sets and determined that the Fletcher bridge is 15'6" in diameter and the Barnegat is 16'4" in diameter. So in 1/700 that equates to a difference of .014"; you could probably then use the Tamiya superstructure as a base for modifications and no one would be able to tell the difference. If you are going to be really critical about dimensions a round bridge is not that hard to scratch build; I could explain how to do that build to you if you decide to go that way.

Good modeling guys,

Bruce

Bruce,

thanks for the info! hmmm that was what i was thinking of - in consideration of the scale i intend to build my ship being 1/700, the differnces in sizes between the real AVP and DE would be negligible. so there!

isnt the tamiya flether bridge already rounded enough for the barnegat? simply looking at the 2 ships the major sanding effort is see would be in the fantail of the DE hull. or do i really have to alter considewrably the bridge of the tamiya lfetcher to conform to a barnegat bridge?

thanks again! :wave_1:

A few of us Small Seaplane Tender (AVP) enthusiasts are really curious as to what this object is.

In this photo of an early AVP, below, (two AVPs tied up to each other) there is an horizontal, rectangular feature located below the Twin 20mm Gun sponson and the canvas covered cable reel. The object appears to be attached outboard of the guard railings with three circular items protruding from the top of it. There are two of these objects one each on the port and starboard sides on the aft p&s quarters.

Initial guesses are smoke screen generators or some type of lube oil or greasing system(s).

These features disappear soon after WWII.

Can anyone positively identify these features? I wonder if similar items appear on other classes of USN ships.

To add to the guess list: Are the larger-diameter cylinders capstans, or reels, of some type for the mooring or servicing of seaplanes? The small adjacent units must be associated with the same function, whatever it was. Maybe to pump POL products of some kind to moored seaplanes. The existence of three would support three seaplanes.

If you can scan the photo at higher resolution, definitive features could become apparent.

Mr. Potter,

You might be on to something with your guess. Thanks. A guess about the circular items that they might be drums or accumulators for a hydraulic greasing or lubing system.

I don't have any better quality images of this particular photo, but am looking for better ones.

Here is a new photo of the USS Duxbury Bay AVP-38, in Norfolk in 1957, that was submitted to NavSource.org by Derick Hartshorn. If you're out there, Derick, thank you so much!

It is a very, very nice shot of the aft boat deck.

I wish that I had this one when I was making my Duxbury Bay model.

Do you have any more, like this? Wishful thinking.

Image

My model depicts the Dux in 1952-53.

Michael Potter wins the prize!

You guessed right, Michael. Per plans for the USS Unimak AVP-31 the objects in question are fueling stations for seaplanes and bowsers. Whatever "Bowsers" are. I've never heard of this term.

Good blueprints. Here is Wikipedia on "bowser":

BOWSER!!

I'll be throwing that term around, a lot, now! :big_grin:

"The Floating Drydock" now has "G" series Booklet of General Plans for Small Seaplane Tenders of the Barnegat class.

The plans are for the USS Unimak AVP-31 in 1944.

WHEC Bering Strait W-382. She has a gray hull color instead of white and white hull letters and numbers. I'd like to know why this was and when would this color scheme have been used.

Since wondering about the gray hull, I have since learned that USCG cutters serving near the shores during the Vietnam War were changed from white color to gray in order to make them not so visible of targets from shore. The AVPs had a 13' draft and could come close to shore, and they did so to resupply smaller boats with fuel, ammo, and provisions.

USS Biscayne AVP-11 was also designated as an Amphibious Forces Command Ship AGC-18 in the Med Sea in WWII.

Here she is in Algeria, closest to the dock, and alongside two Gleaves class destroyers. One of them is the USS Doran DD-634.

Image

This is a nice shot to compare the sizes of the two classes of ships, I think.

A couple of AVPs were designated as Topedo Boat Tenders (AGPs).

Here is the USS Oyster Bay AVP-28 / AGP-6 tending to PT Boats. This would make a nice diorama, I think.

Image

Here the USS Oyster Bay looks really busy tending to her flock.

Image

The PT Boat Tenders had additional superstructure forward of the fantail.
