What if???

We held our own sail design...fest!

Limits (hull)...{UP TO}5 sheets of 1/4"/(6mm) ply, 3 sheets of 3/8"/(9mm) ply, 1 sheet of 3/4"/(19mm), 750 fasteners and 24 oz liquid fastener, 1 gal of sealing resin, 5000 sq in of glass cloth + 75 bf of solid framing lumber.
OR
{UP TO} 250 bf of 1 ft wide by 1/2" thick solid wood planking, twice the fasteners and 1/4 the above resin with 1/2 the cloth optional + 30 bf of solid framing lumber.

Limits (rigging) ...6 sails, 4 spars, 2 masts and a partridge in a pear tree (being as it IS near Christmas )

catagories: Displacement sail mono, displacement sail Multi, planing sail mono, Planing sail multi.

Designs to be completed by 1 March 2010 and freely available as plans by June 30...posted here...ALL of them...even the also-rans.

Judging to be done by poll in each catagory.

The next "Fest" to be row and motor starting 2 March and ending Sep 30 2010, Motors limited to 35 hp, oars to two rowers per boat

Contest open to EVERYONE...with no discrimination. Designs judged on poll merit only.

What have I missed?

Oh...and the Judging criteria!...Suitability of length to beam for the design(1-5), projected speed upwind, beam reach and down wind on a scale of (1-10), suitability of sailplan to hull (1-5), Saltiness (1-5), ease of construction(1-10) vs looks (1-10)(X:Y). Projected cost of construction in or at specified scantlings: (1-20), does it best use the available materials to do what it is INTENDED to do...(A statement of INTENT is needed to judge this) (1-10), ................

 

you could make the partridge first prize

 

That's the Spirit!????

 

You need a limit on the smallest hull allowable. I have in mind a boat design of hull length only 9 feet 9 inches transom to tip of bow with a beam of only 4 feet 0 inches(not counting rub rails).
DSKIRA was recently discussing just such a poll on another thread.

 

Ok...if you don't wan't to use all the stuff available...s'alright wit me! A 4x4 currach would fall into the category too...provided it has a sail, rudder and some kind of leeway resistance.

 

no special tools, amateur construction

 

skin on frame or stitch and glue or taped seams?

 

Ahhh.....my point is being illustrated exactly...how can you have a contest or even a friendly meeting of minds when the criteria keeps getting more and more and more and more and ....nit picky? We could go on for months narrowing down the fields but still someone would pop up and try to add an additional factor. Kinda hard to have fun with something you like when folks aren't willing to just throw something out rather than demand ever narrowing fields of constriction. Use whatever construction method you want...it is out there in the specs, Use whatever tools are in your garage...can you actually build what you design with what you have?///////////...............,,,,,,,,,,,,,,,,,


Awwwww........ **** it....Never mind.....I should have expected this kind of response to something I was really interested in doing.

 

Nonono. I just wanted to know if those methods were all acceptable, not to limit to only those methods!

 

you asked for suggestions and your surprised when you get them?
its still a good idea and the proof of that it would seem to me would be the amount of discussion and participation

 

Ok...you have plywood...what can you do with it and the rest of the supplies stipulated? If you want to use stitch and glue...go for it, Plank on frame...if you have enough stuff...have at it. Skin on frame? don't have any experience with it so I didn't include it but how about 50 bf of framing material and 250 sf of skin material...does that sound reasonable? Solid planks...bring it on....I can't possibly cover all the methods of construction so why not go with what is stipulated in the brief or simply not participate or contradict until your prefered method of construction comes up...perhaps further on if this thread happens to take off. It is still in it's infancy and teetering on the brink of acceptance or dismissal depending on the participation of those who are willing. I am appealing to the mass rather than the specialiser and skin on frame is more of a specific or narrow build venue. Ply is ply, use it as you will, lumber is lumber use it as you will, and now skin is skin...use it as you will (Steel on steel, aluminum on aluminum, carbon on carbon, aluminum on carbon.........I can't enumerate all the possible methods and the spec doesn't spec them).
I still want a decent sailboat that is balanced, works as designed and is a good boat...the end result of all design efforts. Whatever the design...it has to be measured against the design brief or what it was "designed to do" and does it do 'IT' or not? There are so many permutations...I can't cover them all so I am generalizing while at the same time trying to get a comparable set of designs/efforts. The ultimate goal of this thread is to "Perhaps" develop another boat or boats that folks might be interested in building, and so perpetuating the building of boats in wood or at least wood products (plywood) which is why I chose these materials to specify in the original design brief.

 

Well said. This amateur is on it already. It will sail, row or motor depending on the mood of the day. Actual build is much later than design deadline due to certain health issues etc. but plans are coming together.

 

How much these are in metrics:
sheet of ply, 24 oz liquid fastener, 1 gal of sealing resin, 5000 sq in of glass cloth + 75 bf of solid framing lumber.
Or if we aren't so picky can I use 3000x1500mm sheets?
750 fasteners is ok

 

real boats are built in feet and inches

 

Ok...use your preferred method of measurements...sorry if I trod on any 'feet' or toes as far as measurements goes. I know standard metric sheets of ply are close to 4x8 ft...a few mils off,...I don't know what the translation to Bf is though...CCs? 11 m X 100 mm tape comes close to 5000 sq in, should do with a bit extra left over.
