2.4mR / Mini 12's Whats the deal?- Thread starter Dorado
- Start date Feb 7, 2009
More optionsSuper AnarchistI've never sailed one but they look like big fun w/ little hassle Who's sailed them? Where do most of them live? What are the major differences between the 2.4 and the Mini/ Illusion/ Defender? Dawg, where in the delta? Sweet ! That's looking really good. I've read that there are several up in Seattle YC but that may be old news. Newer 2.4's are by far more developed and much better boats the the earlier mini 12's of different designs. The most common design is the Norlin mkIII but there are several others that work as well. The build quality of the NIII varies considerably between differant builders and over time and the thing to look for is (as always) a light and stiff hull that allows you to maximize the ballast. I've sailed a 2.4 in a couple of regattas. Got my ass kicked by the top disabled sailors, but had a few moments of glory despite my ineptitude in the boat. Note: expect ego to take a bruising when you jump into a new class for the first time at a Grade 1 international regatta! It's an absolute blast, because you're so close to the water, but takes some getting used to. You think, hey -I need a little jib trim, and you realize that 1/4" is A LOT of adjustment! Pretty close winded too, I was overstanding windward marks a lot. Lots to do at a leeward rounding, major props to the guys (and gals) like Dawg that have to steer with their hands while simultaneously retrieving the pole, trimming backstay, main, jib and all the dozen little controls. I thought seriously about trying to launch a local fleet, but then started sailing Vipers and having too much fun with that.

Mini 12 or scale down America cupDiscussion in ' Wooden Boat Building and Restoration ' started by bilco , Jan 27, 2005 . bilco Junior MemberA group of my friends and I are looking at building 3 small keel boats (cold mold) to race on the Tamar river in Tasmania. We have a mixture of skills to get us through the project. But finding a design is proving very very hard. We were hopeing for a mini 12 or 2.4 mr looking boat ,but with a bulb keel. Can anyone offer any advice on where to get line drawings? Is it ok to scale down a large boat? We need a design that is great for racing. Raggi_Thor Nav.arch/Designer/BuilderIf you scale down a larger boat you will normally increase the width (relatively) search on this fourm for that. Have you looked at http://www.sailingsource.com/24metre/ ? PAR Yacht Designer/BuilderVery rarely does a larger boat scale down well, particularly if the scaling factor will be big, as would be the case of a 12 meter down to a 2 meter. As a result of the changes made you'd likely have a 2 meter that doesn't look at all like the 12 you're trying to copy. Most of the 12 meter designs that you may be interested in will be under the protection of copyright and it would be illegal to copy it, even if the scale was changed. In a boat that size you just be able to fit your body, let alone counter balance a lofty AC rig. So, to answer your questions about scaling down as you hope. NO, it wouldn't be a wise idea, basically she'd just flop over on her side. If you scaled a 3 meter boat down you'd have a chance of success, but still would require a custom effort by a designer. There are thousands of small "sporty" craft designs available. Build one of those, rather then trying to invent a new class which you clearly aren't skilled enough to do yet. Do a search for keel boats and select a design very close to the size you need. Until you gain a great deal more experience, don't change the scale of the design, just build it and have fun. A used International 2.4 meter will run about 5000 euros, a well equipped one 6 to 7000 euros. You'll be hard pressed to build for that and it's a class boat so there will be locals you can race, besides your friends. Richard Petersen GuestI am missing something on this scaling plans up and down. I have had plans scaled up by 6.5 times in 1 pass, and the enlarged blue prints retained the proportions perfectly. Why was I, O K ? Richard, I don't think they want to decrease the size of the plans, but in fact the design itself. Lets take a look at L. F. Herreshoff's R-boat Yankee and try to scale her down. She's a little over 37' LOD has a 26' LWL, a beam of about 6'8" and around 9' of draft. Bring this down in scale to 12' LOD (approximately 3x reduction) her LWL is about 8'5", beam 2'3" and draws almost 3' of water. This makes a boat narrower then most canoes with a 3' draft. The same works in reverse, except you end up building a boat with way to much beam for her length. A 22' LOA, 20 LWL, 8' beam centerboard sailor scaled up 3 times would make a 66' LOA, 60' LWL, 24' beam centerboarder and clearly too fat a boat. I always forget to scale down the people and " Reynolds numbers and their brethern ". There have been a few attempts to use scaling factors to straighten this out, but none work real well. In small increases and decreases, more then just changing the station spacing would permit, the conversion formulas seem to work okay, but when the ratio gets over a certain percentage it goes to hell pretty quickly. The International 2.4 is patterned after the AC boats and does have an AC style sheer, appendage profiles, bow and stern profiles worked into the design, but that's about as close as they can get in this scale. They do look pretty good on post cards (just like snow) It's what construction workers would call a 80 footer (woman walking 80' away) As she got within 70 feet you'd see what was really going on and get back to work . . . B. Hamm Junior MemberThe Norlin is basically a one design and the most popular boat in the 2.4 meter class. But the class is really a developement class so there should be home built plans available. These boats though are not inexpensive to build for their size, they have relatively high weights and the rig is complicated, along with something like 400 lbs. of ballast. For the past few years I've been working on a very simple mini keel boat of around 12 ft. but designed for homebuilders. Unfortionately right now it's incomplete and the prototype never has been built, not yet anyway. This one would though be a bunch less expensive to build. Bill H. pathetic New MemberHey i am looking for plans for a mini-12 or 2.4 mr for me and my dad to build if anyone could help me out tha would be great. Thanks matt yokebutt BoatbuilderLook a little bit up north, I know they designed at least one good 12 meter up there. Seriously, any decent yacht designer can provide you with a suitable shape. Yokebutt. Tactic Junior MemberWhat about something like this? Tactic Attached Files:marshmat Senior MemberIt'll be hard to find something race-ready in that size. Tactic's pic there looks about as good as you'll get. You need something that's designed from the outset to be this size. As everyone else has said, scaling a larger boat simply will not work. The CG, CB, metacentric height, centre of sail effort, etc. will all be different and the boat will not perform well at all. If you refine your search, you should find a few more designs like the one in post #11 above that will suit your needs. Thee are a few similar production boats avalible.I have searched and searched but have been unable to find plans for anything like this.So I designed my own. I am interested in taking the concpt further,The design i have shown can be built by a amatuer using various strip planking methods. Cheers tactic byankee Junior Membermini-cup plans - FREE see http://www.stevproj.com/MiniCup.pdf doesn't have a fixed keel and the rig is wrong but the hull sure looks right - modify to your liking??? RWL Junior MemberThere is a very active Mini 12 fleet in the Pacific Northwest, with about 40 or 50 boats between the Royal Victoria Yacht Club (Victoria Canada) and the Seattle Yacht Club. I believe the Seattle Yacht club has purchased a number of Victoria designed Mini 12s in the last year or two. They are being produced by John Booth (Booth Enterprises I think is the business name) in Victoria. They are called Deceptions. I would guess you could contact the Royal Victoria Yacht Club to find out who is the class representative this year.

Go to This is an Illusion Mini 12, it is a single person racing boat that was designed to look like the America's Cup 12 meter racing boats. They were first produced in the early 80's, and you can get new ones today for about $7000. They became very popular with older sailors because they have all the control lines of a big boat, but are only piloted by a single person so you don't have to worry if your crew is going to show up or not. (you don't have to use all the control lines, can sail just fine with just the basics) Another big aspect of racing them is that because you sit inside and can't hike out, it doesn't matter how athletic (or non-athletic) the captain is, everyone is equal. Very comfortable to sail, has a molded seat that is nice to sit on and you steer with your feet. Doesn't feel like a kayak, and the opening where you get in is so large that it is very easy to get in and out of, and don't feel like would become entrapped in it if capsized. Just a hoot to sail, very fun - really is a keel boat that you can drive against the wind and heal way over. Very unique feeling being right there next to the water. Has a bilge pump mounted just forward of where you sit so if you take on water, can pump it out. Also has full reserve floatation so if you become totally swamped it will float so you can bail the water out. Currently this one has 250 lbs of loose lead in the keel, and I weigh almost 300 lbs and the hull floats above the waterline, so more ballast could be added. Originally designed to have bags of lead shot put in the keel, but I have some bars lead and some wheel weights in bags in there. The trailer is included, roller furling jib, main, spinnaker and whisker pole. All sails are in excellent shape, very crunchy and practically new. | | Great choice!

New sails (main and Jib) in 2018. 2 spinnakers, spare mast and boom. Holsclaw trailer,(not registered) Rig and SailsAuxilary power, accomodations, calculations. The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more. Classic hull speed formula: Hull Speed = 1.34 x √LWL Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL Sail Area / Displacement RatioA measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more. SA/D = SA ÷ (D ÷ 64) 2/3 - SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement RatioA measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize. Ballast / Displacement * 100 Displacement / Length RatioA measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more. D/L = (D ÷ 2240) ÷ (0.01 x LWL)³ - D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort RatioThis ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more. Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 ) - D: Displacement of the boat in pounds
