This is a follow-up to my entry above.
I understand there is a program that allows the layout of boat hull panels from original designs. The Razor plans that we have all downloaded were drawn by this program for/by Bill Hagerup.
If anyone has this program available, would it be possible to draw out the panels for my square-rigged Footy 3-masted frigate? My only alternative is to try “by-guess-and-by-golly” using paper cut-outs to determine the shape of the single piece which forms both bow and both sides of the design.
The original was drawn on the Paint program, on a Dell computer running Windows XP, if this information is any help.
I can visualize fleets of such vessels recreating the battle of Trafalgar. Or is that too ambitious?
I attach again the design.
Rod. (I was named after HMS and Admiral Rodney)
Forgot the attachment
Rod,
There is an extremely hi-tech route which Richard Webb uses in these circumstances:
Carve a block of foam till it resembles half (or all) of your hull
take paper patterns off the foam surface
Me, I would stick the paper on the foam with acrylic varnish and sail the foam!
Anyway, great design and even better imagination.
You will be aware that there is no rule preventing the use of carronades in a race (unless the shot is defined (by the NSLs) as movable ballast)
We look forward to seeing it in the round - part of the “Scale, Charm and square-rigged footy fleet”

In view of the dire threats and latest weather reports that I may still be shovelling out my driveway in mid-April, I thought I should fire a pre-emptive shot across the bows of the Footy power-that-be and ask if the Footy rules actually state, anywhere, that a Footy need actually float. Do the Rules of Racing and the NOR for the 2nd Postal Classic state that the course must be sailed upon water in the liquid state?
Rod (Just to put the proverbial cat amongst the pigeons)
Rod,
Thanks for illustrating the fine line between wadical and wicked:D
Taking the idea a bit further - what about the gaseous state of water? Having done intense dimensional analysis, and given the maximum volume of the box I estimate that we would have to build a footy to about point 12 noughts one of a gram.
AND I’m not sure what the meaning of racing a footy in a gas would be! Might it get close to my buoyant sail concept?
Why am I considering the whichness of the what
Why indeed do Firstfootys posts generate silence - could they be polarised at 90 degrees to footyforumawareness?
and on the subject of your ship, please meet the plug for ShipFoot (at the back) Hull mouldings tonight

So roll on the Nelson, the Rodney, Renown
You can’t have the Hood 'cos the bugger’s gone down.
Angus
Shouldn’t that be 'ood?
Lets all be careful here! I was named after HMS Rodney.
Although, I, too, seem headed for the nacker’s yard.
Rod(ney)
So I think I can set the all time half lap record…from our second story window.
But that’s just silly, as only model airplane guys would willingly let a new
toy fall out of the sky from sufficient height to do damage.
There has been a decision made about the size and shape of the allowed rudder. I attach a diagram showing my interpretation of the extreme limits allowed. Am I correct in my interpretation?
Does the “notional box” allow for such things as a rudder push-rod that would touch a “real” box?
Rod
Ok, I’ve had a nap, too
Not a dull winter (here in the N hemi), Angus’s brainchild Voortrekker is moving voorward in several locations and several experimental forms of construcion.
Once the prototype is on the water there will be no more concealment - watch this space!
There has been progress! Sloice and ZBF have progressed, not forwards in the case of ZBF. I glassed the hull, using several layers of very light (25 gsm) finishing cloth and epoxy resin.
The small shape made it diffucult to anything other than build “it in the air” so I did, and the very curved sections made it essential to use small bits of glass. it was such a mess that I bound the outside with masking tape and let it harden! Results are attached!
In actual fact it will not be so bad - I will cut/sand it to a reasonable finish then apply a couple more layers of glass as gores. I will then cut it apart at the widest point and extract the foam core. Sounds easy doesn’t it?
I then have real problems - I only have steam 27 mhz receivers, and really need a micro rx to fit in the space - I may well comission her using infra-red transmission and hope that nobody brings a channel changer to the lake.
Anyway the plan is to have her wet this Saturday at Bournville, as well as Sloice and a VT prototype, not to mention a refurbish of Litefoot for me to sail and RAV for John S who is putting a toe in the footy water.
Ah, well there are several nights to go before Saturday

I have been wrestling with the problem of limited interior hull spaces, and the difficulty of mounting off-on switches and charging jacks, while at the same time insuring watertight hatches, all of which would be workable and convenient with cold hands at the pond.
I present here a possible solution as an attachment, showing the charging jack and on-off switch combined into a simple structure that will, hopefully, remain out of the water even during a nose-dive.
The idea has not yet been tested on the water, but is presented here as a possible solution to a bothersome problem.
Rod
I don’t know if the pic is what I intended. Or something has been changed while I wasn’t looking—2.38 Mb ???
Rod
Well, I don’t know!
I turn my back for a few million minutes and it all goes quiet!
I Know that weird portents have been seen: eggs laying chickens, bankers begging and 507s winning St. Modwen trophys!
But we had some great ideas and boats on the stocks:D
I re-read the thread (rhymes!) and was again inspired - you are the greatest thinkers (in a nice, creative weird way) I have come across.
So - back completing the radical footys:
ZBF - progressing well - trial float tomorrow for photos.
If the float proceeds well NOTHING can stop world domination. All the water round here is too murky for photographic purposes so initial ballasting will be in the DFTF, and I won’t use too much bath salt
Thinks: any rival competitor could give me severe problems in a race by altering the density of the water in the vicinity of my boat! Bubbles would cause her to sink, and making a (local) saturated brine solution would poke her high out of the water. I shall just have to hope that none of the likely rivals read this, or use words too simple for them to understand
To recap
Submersible footy - moulded in fibreglass - hull at the bottom of the box - short MacRig - concentric servo torsion rods up the Vertical Hull Extension
- hardly qualifies as radical, really.
AA Cells will now live 2 by 2 on the floor (or possibly the sides of the hull)
Servos on top of the cells (or between the batteries)
Rx at the front
Now for some joining of the hull to VHE, and make the operating arms for the controls
how are the rest of us getting along?:D?
andrew
I recon its your own fault. You congratulated me on my win at Burton before the event took place and so the Fates banished me to 3rd - so I’m not talking to you . . . . :devil3:
But . . . back to serious. I’d noticed this lack of postings too, not only here but on the Yahoo site as well. I’m sure its a coincidence , but it seemed to set in after the announcement of poor Bill Korsgard’s demise.
Cheers,
firstfooty
Perhaps we are all not talking to each other!
Sorry to put a jinx on your race, firstfooty.
I thought that without me to borrow your sails and not knowing that gary was driving thru the night that you would be able to triumph.
You are still my hero and example:D
Assembly and ballasting tonight, alii aequalis, followed by trial sailing.
Since the last photos I have had to add an external carbon fibre corset at the mast position, and want to add an internal “cuff” so that the bow cap is a plug-on and tape in position fitting.
I have had a severe de-mouldng problem! I wrapped the plug with a spiral of PVC tape expecting it to act as a release layer. It is now well bonded into the fibreglass and I have completely given up the idea of being able to remove it. Does anyone know if glues will bond to it - apart from my laminating epoxy - which I know bonds well:mad:
photos follow
andrew
Andrew,
How about kitchen Cling Film or plumbers PTFE tape for using as a release agent ?
Cheers,
firstfooty
NOW you tell me:D
I normally use cling-film or parcel tape, but the torpedo shape lent itself to a spiral wrap of narrow tape. PTFE tape would do the winding, but I fear it would “squirm” aside as the glass was applied - I did a lot of smoothing with gloved hands
I can see this wil be one of the trial sails at midnight - I am going to sit by a log fire and tell sad stories of the death of kings…
andrew
Back to form then Andrew? I’d argue you’re displaying too much cogency in the last posts and fear therefore that you’re giving away the game. Perhaps squid ink in the eye would serve to fool the blighter and drown the armada a priori … come to think of it, we haven’t heard much of Mr Heron, Mr McCormack or the Ogre either recently …

Sorry - have I approached lucidity? I am reminded of the motto of consultants - “never knowingly implemented” My restless mind is once more questioning the whichness of the what. Well it keeps me sane, ha ha:D
ZBF was due to get christened yesterday but I could not find the Buoyancy Compensator - I have put it somewhere safe and it is safe from me, at any rate:confused:
Tonight I will carve a new one. I was expecting to have a range of them anyway and commit maritime radicality - there really can’t be that many submerged yachts around 
(even though american subs have sails)
While contemplating buoyancy as it applies to ZBF I realised that there is the possiblity of hostile action SINKING her!
Passing close behind Gary when he is using the “sanderson paddle” to froth up his bath salts could reduce the water density so much that ZBF would sink! This would reduce displacement drag still further, but reduce power from the sail:mad:
Extending this thought (logically and reasonably) to the general sense I bethought me of ways of changing the density of water around Footys for good or ill.
F’rexample - dropping a “depth-charge” made up of a CO2 bulb with water-soluble plug (or bathymetric valve) could produce a vast cloud of microbubbles in over a small area so that any boat in the area would immediately sink! Evil, (but some Footyers do it regularly anyway)
Come to think of it Darcy is somewhat flatulent when feeding on shoals of beans…
Conversely: a strong solution of a water-soluble salt would locally increase the water density and cause the boat to rise because of the additional buoyancy. Similarly plaster of paris could encase and retard a following boat and various hydrogels could be deployed as “aimed weed”
Now I would never use such underhand methods, (even though my need is great) but I realise that I will have to my fellow competitors carefully while sailing ZBF

as normal as the next man
