Hi there Tim
The strip, I believe, on the plan is referring to the rubbing/fender strip which runs around at deck level on the tug. 
The height of the frames should be in the middle of this strip width.  Therefore when you add the bulwarks and decking you then apply the rubbing strip which hides the joint between the bulwarks and planking. 
The angle or the radius on top of the frames is the camber and there is a correct formula for calculating the height of this – to which I will have to look this up  to refresh one’s senile memory (getting old you know) .   I do believe there is a centre height drawn on the profile plan if you have a look – it gives you a height to the centre of the deck (I am sure).
Sorry I cannot be more help, because I gave the plans away to someone on the forum – so I am having to go back to the build and scrutinize from there.   
Anymore queries, please don’t hesitate – AND PUT SOME PICS OF YOUR BUILD ON  :-))

aye

And yes the radius is what i was refering to (not sure why i said angle  {-))
Pics will follow when i have something of import to show, unless you want to see photos of my photocopying ability  :D

Hi there Dave

Sometimes there isn't a picture - but there is a tiny box - there is a code number at the side of the box.   If you click on that, it normally brings the picture back - this seems to be a recurring problems after a few crashes and reboots of Mayhem.   I noticed we have totally lost all the pictures for the build of the MSC Archer Tug which I did a while ago.   There are also several pictures missing off the RTTL build 2751 and other builds on the Forum.  Maybe something Martin can look into to see if he can retrieve them.

Last but not least, have you started any builds yet?  Because one of the good builds is a plan for the beginner (The Swordsman).

Hi Bluebird

Many thanks for your reply....I have a feeling I may have asked you this before as I remember the answer you gave me  %)

I have read through and looked at every last bit of this build and I love it

These are the kind of builds, and your knowledge that keep me coming back, I absolutely love it

And no, no first build yet, but as this is my 3rd time getting in to RC boats again, I am determined to give it a proper go this time

On to re-read the Vosper build!!!!!  :-))

This is a brilliant build that I have only just found, I visited the Tug at Ramsgate last year for inspiration whilst restoring a Caldercraft Imara, love the sketches from a proper modeller not just adapting available castings, like I would.

 Hi Bluebird
This dopey old sod is confused.
I have taken on the Cervia build and confusion reigns as to what the correct height is for each frame.
At first I took the height from boat bottom (hull) up to the bottom of the rubbing strip and traced frames ¼   and ½   
OK I thought and had a quick look at your build to compare notes and sizes and my findings left me baffled
My measurement for frame ¼  from hull to rubbing strip up the centre line is 90mm
For ½ from hull to rubbing strip is 100mm
OK so I looked at yours (photo 9 traced frames on materials) and compared sizes
Your heights where as follows (yes I took the fact that the sizes were reduced by the photo and used your ruler as reference)
So frame ¼ from hull (??) to rubbing strip (??)is 76mm (give or take a gnats whisker)
Frame ½  from hull  to rubbing strip is 80mm
Any idea as to where my discrepancy may be ie where to where should frame heights be measured please?

Does this help at all, it is of a sister boat to Cervia, but does give the frame layout .

Hello there Fred

Welcome to the Madhouse :-) okay
If you have a look at picture 6 on the build thread - you will see a red and a black arrow - both pointing at lines - drawn on the frame plan. 

The red arrow is the outer deck line height.   The black arrow, in actual fact, is the top of the rubbing strake which goes on the outside of the hull.  So, the top measurement is taken from the line where the red arrow is pointing at.   

Look at picture 7, you can see that this is of the 'keel' area and there are 2 more arrows pointing at lines here.

The red arrow is where the frame ends.   The black arrow indicates the thickness/end of the external keel.  So, the measurement of your frames are taken at where the red arrow is pointing at.

Now, if you have a look at photograph 1 which is the side view of the hull, look closely and just above the top of the rubbing strake you will see a dotted line, which follows roughly the shape of the hull - this is the height of your frames in the centre of the hull.

So it gives you to the top of the camber of the deck in other words.

Hope this is of some help.

If not - let me know and I will re describe what I have said as sometimes it is difficult to put into words (if you know what I mean).

Lets know if you need any further help.   Don't forget as well, I have already reduced the size of frames by the thickness of planking - that thought just occurred to me.
