Topic: 103 class hull outlets
http://www.ptboatforum.com/cgi-bin/MB2/netboardr.cgi?cid=101&fid=102&tid=3099



Hi all,
Newbie question. Sorry if this has cropped up before, but I am looking for information on the various hull side outlets on the early 103 class boats. I am building the Italeri 1/35 109 and I am comfortable with the D shaped fairing and round holes near the chine on the bow, and the two D shaped outlets just below the forward torpedo pivot. I cannot see evidence of the three other round outlets near the stern as shown in the kit. Does anyone here know of a drawing of the side outlets? I have trawled the internet and other references with no result so far.
Many thanks,
Stu Hurley

Hi Stu,
Here are some of the best hull photos I've found because the color is so light making it easier to pick out detail. Hopefully somebody will post some good factory drawings. The ones I have are not clear enough to make a definitive call. Here are photos of PT-103 and PT-117 that may help provide some clues.

Hello again David,
Many thanks. These are a great help. They certainly do not show the three round outlets towards the stern and there seems to be a couple of extra outlets on the port side midway down which are puzzling me.

Regards,
Stuart

Here's an outboard profile showing the starboard side outlets, scaled to 10 pixels per inch: [url]http://www.pt103.com/images/asst/BureauOfShipsOutboardProfilePlan496536trimmed_Scaled.jpg[/url] I don't think there's a similar view of the port side though... nor do I know if the drawing I posted shows all of them on the starboard side. Your best bet would be the Elco drawing DVD and a lot of .pdf viewing. The bottom also had a number of inlets and outlets. I'm sure not looking forward to digging them all up for my pt103 project.

Check out the parts catalog Dick has made available for download on this site. It shows locations of a number of inlets and outlets for the salt water system, toilets, sinks, bilge system, fuel vent and drain, etc.

I am not certain, but I would venture a guess that these outlets you speak of are for the vent and overflow of gasoline from the fuel tanks. I say this because we have similar fitttings on the hull of Higgins PT658. The fittings seem to be in the general proximity of the fuel tanks. I know that Dr Al Ross would know for sure. Jerry

Several years ago I researched the Elco blueprints to determine which items indicated on the profile view drawings were actually ports being used. I reviewed the drawings that lead to the following discoveries, as indicated on the marked up photos below. Drawings reviewed were all Bilge Plumbing, Fuel Tank/Line Vents, Water Plumbing, Battery Box Vent. Many of the Plumbing lines such as, Toilets, Lavatory Sinks, Fuel Drain, Engine Room seawater Cooling Devices intakes and outlets, some Bilge Drain outlets, exit on the underside of the haul.

Nice work Dick, that will come in handy later!

Stu, I saw on the Model Shipwrights site that you are going to replicate the 109 on the Stanton. Here's a higher res image that you might find helpful: [url]http://www.pt103.com/images/ptpics/Photo_Scan_PT_109_Ferried_Stern.jpg[/url]. It's really hard to tell if it is all the same color or not.

Gene's PT King site shows the 103 and 105 being shipped out with the chart house, bridge, and maybe the torpedo tubes a lighter color than the deck. He used to have a closer image of the 105 that very clearly showed it but I can't find it anymore. You could see overspray(?) onto the deck, and what appears to be the same lighter color on the deck under the torpedo tubes. It's still visible on the images on this page though: [url]http://pt-king.gdinc.com/PTsquadronfive2.html[/url] I can't pick the color difference out on the 109 shot I posted though.

Dick, how do I add the signature "You got questions? I got confusion."

I'm assuming you mean Italeri parts PH22? On the hull, these outlets are all in the engine compartment. I've been looking over the schematics in the ELCO Parts Manual, but haven't found them yet. I think the forward one is the battery box vent on Dick's annotatted photo.

It just never ends, the things you continue to learn about the boats. Nice job Dick pointing out what each one is............

Glad you found us useful Stu.

Maybe one is the auxiliary generator exhaust Al? I dug through the DVD drawings but could only find rough location details for PT 565-612 (ELCO_Roll_5535-3_72SCAN_00255.pdf).
