David Macgregor drew a set of plans for Thermopylae I believe.   His plans went to an outfit that really ain't much of an ally.

This said, collect plans,  collect books.  I think that collecting kits only serves the kit manufacturers.  The old pre-fire Mantua kits look to be really awful to me.  I think three of their most popular subjects are the same hull in different clothes:  Bounty, Endeavor, Beagle.  For their kits in general:  All of it seems to have been just the minimum required. 
 
A clipper is a major project.  A composite hull post 1860 clipper even more of a challenge.  Large hulls at a small scale is requiring miniaturist skills.  Unless it is a widow recently stuck with "toys" that she resented having funds spent on when obtained,  I suspect that "deals" for old kits are gilded bricks.  Someone trying to recover some of the money spent on really poor decisions about illusions, dreams, and mirages. 
 
Here is an idea:  Keep a diary of subjects as they grab your interest.  Have the links and references there.  Buy no kits until your board is clear.  When you get to the 'buy another kit' stage, you will be surprised at the number of diverse trails, strange ideas, and dry holes there are in the diary.

in reading MSW build logs for kit built models I find that builders often get concerned with details.  This seems to be especially true with rigging.  Almost never does the builder seem to be concerned with what should be the question to be asked before buying the kit in the first place:
 
”If I build this kit will it accurately reproduce the lines (shape) of the actual vessel’s hull?”
 
In the past, some kit manufacturers were, putting it politely, “casual” concerning this.  This could be particularly true of Clippers as overlooked subtle differences between different vessels could still allow models of different ships to both look impressive. There was also a tendency by manufacturers to save money by widely spacing bulkheads, supposedly solved by the ubiquitous double planking.
 
The manufacturers of POB ship model kits seem to have upped their game in the past few years and several offer kits that can produce accurate and stunning models.  I would, therefore, be cautious about buying an old kit.  
 
Many kit builders also have a stash of kits that they intend to build someday. These stashes can represent many lifetimes of ship model building.  My stash is not ship model kits but books. I have shelves of books for researching projects that I was once excited about building but now realize won’t get built.
 
My advice to you: Finish the project(s) that you are now working on, and take satisfaction on jobs well done.  Then decide what you want to build based on skills and interests at that time.  Meanwhile save your £100.

Two of the reasons for preserving an obsolete ship:   
sentimentality - a cultural symbol -  purposes that both Constitution and Victory serve quite well
true historical exhibit - as direct evidence and data for what the ship actually was in the instant of time it purports to represent. 
 
If the Ship of Theseus - had been repaired by using the same source material (species of tree, etc.), with the identical shape, and attached using the method that is identical to the original - even if none of the actual molecules are those of the ship as launched - it would be just as valid as if it had been teleported.  The information would be identical and equally valid.
Both Victory and Constitution are failures by this standard.   Constitution underwent "improvement" and "modernization" probably about every 20 years while on active serve  and after it was saved from the breakers, been manipulated and adjusted to the preconceptions of whatever committee was in charge when repairs of the effects of time, oxygen, microbes, electromagnetic radiation, was required.   Victory has seen its share of the same.   Both are chimeric rather than being a frozen instant of time.
 
Would that we had now, and in the past,  a more elaborate and minutia obsessed version of HAAMS  for every vessel of some importance.

Unless the color is not appropriate, using it 'As Is' will work;   no treatment is necessary.    If darker is the goal, a wood dye will do the job.
Blue Mold is not like the fungus that turned a trunk of Apple that I had not prepared correctly into meal. 
 
Oxalic acid does work.  I used it on a door of an old book case, Took it back to looking like fresh cut wood.  It was an antique - extreme refinishing was a bad idea - destroyed any value,  but the stuff worked.
 
As far as I can tell, Blue Mold is benign except for the color thing.  If only we could save all of the infected Holly and off-white Holly from going to the breakers and buy it.

I harvested and cut into billets some Holly from a cousin's land.   When I rip cut it water almost squirted from the end as the blade pushed it.  This told me two two things:  Holly contains a lot of water.  Holly pore channels are highways.   Blue mold will out race you unless the Holly is harvested in Winter and unless the cut ends are sealed and the wood immediately goes into a kiln.  I did not wish to case harden my supply, so I set the temp in my foam box to be just a bit higher than what I thought a fungus could survive.
The strain of Holly on my cousin's wood lot is yellow, not snow white.
 
From my traditionalist perspective, you are not in trouble at all!
No species of wood used for an actual ship was snow white,  so the color of Holly that is sold does not fit a ship model.
The yellow - or blue - or grey (which is what some of my infected stock is) is actually more appropriate.
The Blue Mold fungus does not affect the structural integrity of the wood.  Holly is neigh on to perfect for us.  It works for part quite well and for planking, nothing else bends quite as well. The grey or yellow would closely match the color of an actual deck - Sun bleached and salt water abuse.  For tar foot prints and drips from standing rigging additional color is needed.  The snow white decks planked with marquetry Holly is flash and not realistic.
Holly readily takes a dye.  Perfect for black wales.  The blue will probably want a dye if you paint with wood.  Alcohol based aniline dyes -  I do not see that the additional depth from water based aniline dyes would show at model scales.  It would just add a grain swelling problem and a longer drying time.
 
Unless you are dead set on having it be snow white - you are golden.   Holly over here is now absurdly expensive.  I suspect sawyers trash or burn infected or off color Holly.  Would that I could contact one and take what he thinks is trash off of his hands.

I think this was taken from Steele 1805 plates.   A pilot schooner was probably about at the limit for long term deep water sail.
Since it is from Steele,  his table of scantlings should serve.
Western wooden sailing vessels did not have bulkheads -  except perhaps some fishermen with a live catch hold.   They had deck beams.
The outer ends rested on clamps - thick inside planks.
The small vessel I have selected from Steele is the 10 guns Brigantine  - small two masts
clamps  # 2   3.5" thick at upper edge  2.5" thick bottom edge  the pair are 13" wide ( 6.5" + 6.5"  or  7" + 6" - like that)
Deck plank   3"
Beams  round up 6"    sided 9.5"   moulded 7"    # 16
 
Use the location of the hatches and masts  to give a starting point for the spacing.   I do not have data for how wide the space between the beams at each mast is, but it was fairly close with room for changing the angle of the mast.
The hatch just are.  The other beams are probably at regular intervals.  A deck house would be a hatch.
 
The beams are a series of arched timbers  9.5" wide,  7" thick  - each has a different length-   Because the peak of the arch for each is 6" in the middle, the curve is different for each one.
 

Richard @Richard Braithwaite,
When I billoted my Holly, the near stream of water being pushed out of the cut end by the bandsaw blade told me that Holly has water tubes that communicate readily. 
Your paint MAY have saved the interior from the Blue Mold, but I would not bet any money that I could not afford to lose on that being the situation.  But, even so, that would not decrease the value of the wood for model ship building.  The structural integrity of the Holly is not affected by that particular mold as far as I can see.  The color change is more in tune with ship building wood than is the snow white Holly that has become so expensive.  Robbins egg blue would be weird,  but Holly readily takes up alcohol based aniline dyes, so that is easily fixed.

To add to your possible options:
First,  I have been following this since the early 1970's and subscribing to all of the English language "journals" as well as about every book as it came out.  The only instance of having a deck plank butt on the same beam with every other strake has come from OcCre.  I have no idea where they came up it something both hideous and dangerous engineering.  Having ax handle diameter trunnels - standing out like carbide lamp beacons - at and only at each butt - is graphitti. 
 
Wood swells across the fibers.  They are not muscles.  they do not get longer.  If the end to end butt is tight when the deck is laid, a wide caulk filled seam is not needed.  The end to end butts would be difficult to see.
On actual ships that were well built, the deck trunnels were supposed to be as invisible as possible.   If it is to be modeler's convention show off deck trunnels,  there is a rigid pattern to be followed - and the contrast should still be subtile. 
 
Polaris is more boat than ship.  I do not see when it was supposed to have been built - or where - but in early to mid 19th c US, 40 foot long 10  inch wide planks were specified for corvettes - much larger.   A single plank per strake - without a cross scratch - would pass muster.  If you are laying it on a subdeck before it joins the stanchions/top timbers and outside planking a single is easy.  Trimming off the overhang at each end is easy.   If the deck is laid on beams.  with waterways in place,   the complex ends are more difficult to fit.  Jogging, nibbing,  or curved  starting outside in.   Getting a winning role of the dice at both ends is difficult.  Here two pieces may be easier.  A simple 90 degree join in the middle is easier to pull off.
 
Higher cost and not so good a choice for end cutting.
Choppers - crush fibers - even as a knife blade - they do not cut. 
HF Drill Master 2 inch - motorized - needs a lot of work on the work surface- kinda dangerous - throws what it cuts off  - is clearance so is probably soon to be extinct - MicroLux is probably the same unit.   Prozzon wants your next born for something 10 times more expensive and maybe 25% better made.
 
Quick and dirty:
Use a saw - a razor saw - mass market work fine - Zona , Exacto,
I prefer a cut on the pull stroke.   This requires either a Japanese mini saw - expensive - or a razor saw with a blade that can be separated from its backing and reversed.
 
a miter box - depends - with a saw with teeth that have set, the slot has to be wider - so some play.
Protractor:
Draw a line and cut by eye, then:
 
Get a 3/4" thick square of wood  12"x12" is enough - plywood is OK,  an off cut from an Oak stair tread wonderful.   Overhang the end of the plank.  Sanding blocks -  80 grit to remove a lot.  220 grit to finish.     If you can find sand paper with a simple paper or cloth backing - not the non-skid stuff - a coat of rubber cement on the block and on the paper - wait 15 min - press together - endless supply.
 
I found a $13 Porter Cable replacement miter gauge that might fit the board.  A stick of wood with a center pivot,  a distance out spike or screw, and a protractor with movable arms may be all you need to get accuracy for any angle.

I'll kick in with my $.02 (US) for what it's worth.   Kits are basically either something someone wants to build for their mantel or maybe some they just like doing.   For other, they are a starting point to rework the kit into something realist to the actual ship.  Nothing with either reason.  As far as kits go... for example, the Vasa... or Victory.  Lots of them around from different manufacturers.   Accuracy.... is kind of "meh" for almost all of them but are a few that are really detailed and accurate.   Two of the kit makers (Syren and Vanguard) pride themselves on accuracy.   The key is that you get what you pay for and accuracy is one of the variables along with materials.

Although Beagle was at the verge of explosive shells - which made their own splinters,  it was of the kinetic ball era.  Additional sources of wood splinters on deck - not all that wise.
The boats in the waist tended to be nested.  They were wood.  They probably required having their hull planking kept wet enough that they did not desiccate enough to open their seams. 
That is not a good storage environment for loose parts and equipment.   If Beagle's task was like that of the later U.S. Ex. Ex., the primary function of the larger boats was for mapping.  The smaller ones were probably better at getting onto and off of a beach - water, food,  getting investigators on to unknown shores.
 
 

What I mean by tunnel vision in this situation is to focus on building Roar Ege as close to the way that Billing as designed it.  I think that any time and effort spent on trying to augment or add realism would be better spent on a later project.  A time tested, perhaps THE time tested, path into scratch building is to augment a kit with more sophisticated elements.  I think that this particular kit has too much that is too far from real.   It would be like starting in a deep hole.
 
In preparation for composing what is real (or at least my admitted limited knowledge of what is real in Viking practice), I scanned all of the Viking kit build logs.  Which are authentic looking?
At least as far as the hull and the planking - which is pretty much my area of focus.
Realistic seems to be  Marine Models Dragon class solid carved, Dusek Gokstad,  Dusek Knarr, Artesania Latina long boat.  The sheer of all is sort of flat.    Anything but realistic Billing Oseberg, Roar Ege,  and Amati Drakkar.
 
I thought that the impossible planking of Amati: 
and Roar Ege, which is a bit less cartoon -  and pointing out that the planking was freed from Oak trunks/balks using a maul and wedges - I don't see how an individual smith could fabricate a saw.  For your kit, the green box is the plank that this plank would have to be spilled from:
That these extreme - probably for show - stem and stern were large carved timbers - not actual planks: 
And these two links are from logs here:

That the planks had lands in the carved piece: 
Then I realized that the kits with these extreme curves on their planking were never intended to be realistic.  It is a cynical method to avoid having to deal with providing the proper stemson and sternson.   At least for Roar Ege,  I think that the planks are far too wide.   The extreme twist that includes countervailing  directions for the kit planking at each end  is something that I see as being a frustrating combat for a builder.
 
Being totally outside my Universe,  I am not qualified to rule on which short cuts are acceptable in a kit.
 
Oh,  about one of my POB terminology complaints -  on most POB ships, the central spine fills the midline of the whole hull. Usually it reaches up to the lowest deck being included in the model.  For Roar Ege, that part may only be as much as the actual keel.  In this situation naming it "keel" would be correct.   The possible horrible part would be if it is plywood, with end grain showing where it should not be.
 
😉   This is meant to be fun.   Even if we were part of a university naval architecture department/museum and hair splitting stroum und drang  - actual models are no longer in favor.  Those decisions seem to be in the control of individuals who have the equivalent of a life long continuous release LSD depot somewhere in their body.
