I know that the antenna mast on the Vosper 73ft. Type I is
located portside just aft of the bridge and mounted on the side panel.

Is it on the inside or the outside?

Airfix instructs to mount it on the inside but some modelers seem to mount it on the outside.

Which is correct?

I have not been able to find pics which clearly indicate
the correct position.

Not sure if this will help Joe..









Looks like it's mounted on the exterior of the deck house form what I see...if this is the same boat!

Hi Todd,

Thanks for your reply but it is not the same boat...those are the drawings for 72.6 ft.
which has 2 torpedo tubes and does in fact have the mast starboard and on the outside.

The 73 ft. Type I has 4 torpedo tubes and the mast is portside
but all photos I have are not clear on its location.

I think I will just mount it on the outside and disregard
the Airfix instructions.

Thanks again,
Joe

' Allied Coastal Forces Vol II by John Lambert & Al Ross '

In which there are pics indicating the mast outside

The plans covering MTB's 379, 380 - 395 clearly show the mast outside the cockpit on the port side

Hi Kev,

Thank you so much for confirming this!

This is one book I should add to my library.

Cheers,
Joe

John worked from the originals, so his stuff is ultra trustworthy. I have a copy of the original Vosper dwgs for this group and it shows the same outboard fitting.

Todd,

What company produced that Vosper drawing with the number 457? MTB 457 was a 71'6" British Power Boat Company MTB!

Hello Al,

Thank you for confirming this and I am looking into getting
the book...having read reviews, it is highly recommended.

Thanks again,
Joe

Although,

These photos seem to show the mast on the inside of the bulkhead of the bridge:

But, sir?

In this photograph is dead-on straight on to you... the photograph CLEARLY shows the mast located on the INSIDE of the bulkhead of the bridge. There is no false impression to be derived from its perspective, sir. It's from straight on - not on an angle.



If the mast was attached to the outside of the bulkhead of the bridge, sir, it'd be seen where the arrow is pointing to.

[quote]If the mast was attached to the outside of the bulkhead of the bridge, sir, it'd be seen where the arrow is pointing to.



The arrow is pointing to a venturi (an air deflector attached to the open bridge sides), not a bulkhead. The mast is attached to the aft cockpit bulkhead and port spray shield.

This is from Vosper drawing 11446 73' MTB 379, 380-395:
Mast is clearly NOT inboard.

This is an enlargement of a photo of MTB 380. Mast is clearly seen aft of the venturi:

Hi Al,
Having consulted the John Lambert plans on your and Kev's recommendation,
it is very clear that the mast is on the outside and your photo further
confirms this.

Thanks again for your assistance.

With all respect, Dr. Ross,...

To my eyes ... it's inside. But, I will say I could be wrong, ... but a little voice is telling me I'm not ... if anyone can find a photo which definitively shows it on the outside - I will gladly defer to your call.

Additionally Dr. Ross - Look at where both of my arrows are pointing to, sir, it's the aft bulkhead of the cockpit, and in line with the sprayshield, I really do think it's inside ... but, like I've said, I could be wrong and will admit it if proven wrong.



And about in this photo, sir? It is no where near the venturi ... and inside of the bridge, sir.

Hi Tim,

That is a photo of a late war Vosper Type II 73ft.
The armament is different and the mast has been
also relocated.

It does not depict the Airfix 73ft.Vosper Type I.

I found this photo and when enlarged distinctly shows the mast
on the outside of the bridge casing or bulkhead...not sure
which term is right.



Thanks again for your assistance.

Cheers,
Joe

If you read the header for this thread, you'll note that Joe is asking about a 73' Type I. This group comprised MTB 379, 380-395. All of the statements made by everyone except you are consistent with the Type I configuration.

The 73' Type II, which included MTB 523-530, 532-533, has a different superstructure, deck layout, and armament configuration from the Type I. The Type II has a mast on the center line. You are using a photo of a Type II to support your argument about a Type I - doesn't work. They're different configurations.

Al, ... with respect, sir?

Two of the photos I used are of a Type I, especially that bow- on shot ...

And, as I said, I was just trying to help. And, fell short.

I apologize.

Tim
