Methinks I made a boo-boo with the previous posts' photos so I'll try again. Sorry about that.

That's Great Popeye.
You can really see how much work has gone into the rigging.
And thats the KISS version  :-)) :-))
I wish I had the patience to do that sort of detail.

Great photos Popeye - now I can see 'em!  :)

She's so neat and clean - sharp as a tack.

Did you do anything in particular about the foot of the fore-corse?  Some folks put wire or plastic rod in the bottom hem to act as a Bentick yard so the sail will set better when sailing on the wind without curing back on itself.

Negative, though I have this in mind as a retro-fit should  extended sea trials so warrant..

PAINTWORK.
All woodwork  - with the exception of the decks – was first sprayed with Halfords acrylic primer followed by top coating with good ol’ Halfords acrylic car sprays. The natural state of these finishes was too glossy for my liking as a result of which everything, including the resin sealed deck, was over-sprayed with  Humbrol   Matt Acrylic  varnish which gave the final result a far more realistic look in keeping with the models’ scale and purpose in life:-

Masts, Bowsprit, Jiboom – Vauxhall Gazelle Beige
Spars, Tops, Gunwale rails, Hatches – Black
Bulkheads and inner bulwarks – Peugot Cherry
Transom – Ford Blue
Above waterline - Black  and Primer Filler Yellow Ochre
Below waterline -  Polar White

BALLAST.
The completed model including sails, servos, motor, batteries etc., weighed 10lbs. and test tank trials determined that a further 17lbs. ballast would be required to bring it down to within 1/8”’ of its’ waterline. The bolt – on fin (Post 4) weighed in at 13lbs when filled with No. 6 Buckshot  and the remaining 3lbs. was accounted for by moulding sixteen (16) x 4oz. lead billets which were placed in the hulls’ bottom between what remained of the balsa frames. A small wire loop was set into the top of each billet to facilitate positioning /retrieval.

CREW.
The resin moulded crew were pressed into service from a local toy shop. Weapons and sundry  accoutrements  were confiscated, and some limbs repositioned, before the motley crew were kitted out  (repainted) by the Bosun.  Bilgerats can be beached at will  if in danger of entanglement in the running rigging!

ANATOMY OF A MODELLING PROJECT.
My previous sailing models have been conventionally rigged vintage sailing craft though I’ve always been attracted to the beauty of square riggers and the nostalgia they evoke.. However, having no previous experience of square riggers I boned up on the  subject by referring  to model magazines, MBM and RC Groups (USA)  forums and numerous books - including the following principal publications - before committing myself to the building board:-.
Rigging Period Ship Models………….Lennarth Petersson………….ISBN 978.1.86176.061.6     
Planking Techniques for Model Ship Builders…Donald Dressel…… ISBN 978.0.8306.2868.1
Building a Working Model Warship (HMS Warrior 1860)…..William Mowll…. ISBN 1.86176.041.8
Scale Model Sailing Ships……John Bowen (Ed)………ISBN 0.85177.111.4 

Rigging Period Ship Models in particular, with more than 200 detailed and crystal clear diagrams  relating to all aspects of rigging, was an  indispensable  source of information and is a must for anyone  tempted to scratch build a working square rigger.






I was prompted to build Thames in particular,  as a result of reading  a short article about HMS Supply, published in Model Shipwright (No.95 March 1996).  A beautifully drawn plan accompanied the article and formed the basis for the construction of my model.

What subsequently transpired is, to coin a phrase, history.

END. :-)

Wire, plastic and Benedict yards to my eye look awful ,they distort the sail and make t look unnatural look at any photos of replica ships running and you will find the forecourse bellows out from the yard And lifts the bow this is the only sail that has so much lift but with wire,plastic ,or a Benedict  it takes up the wrong shape and acts as a depressing sail which in a decent breeze can bury the bow and in extream cases can cause the ship to gripe (Lift the rudder out of the water) and broach too or capsize

Jimmy, it's possible to get the billow and lift with Bentink booms. It depends on how the fore course is attached to the Bentinck boom, and how the boom is attached to the mast. If either attachment is too snug, then the sail is flattened. My booms, for example, are loosely attached to the mast with a rubberband. This allows billowing and lifting. I've never had a bow bury, and I've sailed my Pamir in winds from zephrs to scale gales :-).

Boyle, 1930's deepwater sailor and squarerig modeler, was of the opinion that duplicating real practice was silly if the modeler could improve the aerodynamics (he did not call it aerodynamics, of course). He liked flat sails and Bentinck booms because they increased the ability to work to windward. I like the same. 

Boyle took pride in the prizes his squareriggers won when competing against model sloops. In those pre-RC days, the ability of a skipper to trim his vessel to follow a set course was important (points were awarded for making a specific landfall, along with points for speed).  The sloops he competed against were faster than his squareriggers, but sailed a more erratic course.

But each modeler is able to choose which part of the hobby is most important to himself, of course.

Looking at Thames, I don't get the impression that Popeye is following Boyle's philosophy.

A model's ability to work to windward is paramount.  We don't sail them on trade-winds for days and weeks at a time, or even hours - we dart around the pond like squirrels at play, holding a course for minutes at most, and most of the time, our model is clawing it's way up wind before it finds itself in the fescue at the lee end of the pond.

A narrow thin strip of styrene, or trimmer string, inside the foot of loose footed squares, stiffens them enough so they don't try to roll their clews in yet is flexible enough for the sails to "belly", they're a bit like those plastic strips in the collar points of better shirts.  Functional tacks should be employed, even if they're just elastic pulling against the controlled sheets.  You could just keep the courses furled and avoid the entire issue.

The match of HBMS THAMES and the PRIVETEER FREE BOOTER was a foregone conclusion despite THAMES much vaulted crew, this Lubberly lot were so out gunned & out sailed by the vastly more experanced FREE BOOTER that she took pity on them, Gave them some lessions in sailing helped re-rigg this pretty little vessel (Scrapped the Benedict Yards) she sailed much better ) Kicked her in the back side and told her to come back next year when she had some sea time and with some real seaman on board

From the looks of it, I'd say it kills using the combined smell of fish and feet.

Jerry
If you've been on a small sailing ship with a large crew in heavy W/x I cannot Dineay it gets a bit whiffey down below, but as for her Fighting & Sailing ability I'd say that would be down to the training and sea time (14 years) that this crew and Her Master (55 years) has and the 5 long nines & 8 X 12 pounder cannonades that have more often than not have added their weight to the argument ...But ..if you would like to try your luck I'll more than likely be at Wicksteed again this year .... If your delicate nose can stand the smell of a real fighting ship.

Oh Jimmy, I so wish I could fly over the pond and take you up on that challenge.  If my lottery pension plan pays off, I promise publicly, here and now, that will be at the very top of my list.
