After using plywood construction, which could also be a that, the Laser (launched in 1971) drove a wedge stepping-stone to the Finn. The first OK was into the dinghy market, driving the OK and other launched in 1957 – a year after Jack Holt’s popular singlehanders into a backwater. More ▲ YachtsandYachting.com compromise. Tony Thresher builds all-wood OKs near Oxford, but there is currently no glassfibre builder for the class in Britain. The closest are Jurgen Hein near Hamburg and P Oddesborgs near Copenhagen (which come in £500-£1,000 more expensive than all-wooden), although the UK association is hoping to appoint a major new builder. Further afield, OKs are built in New Zealand and Australia — where the 2006 world championship is being held in New South Wales this February. Some European sailors have opted to buy a new OK ‘down under’ for the worlds, using advantageous exchange rates to balance the cost of bringing their boats home. Nick Craig’s OK was built at Cookson Boats in New Zealand, best known for top racing yachts like ‘Pyewacket’, ‘Virbac’, ‘Playstation’ and the NZL America’s Cup series.

  • Rig Tension Pdf 96 KB
    29 September 2011 Hi Eduard, My thoughts re rig tensions. All other things being equal, and in the case of the 9ers, they are roughly equal, then Rig tension is firstly all about ForeStay [F/Stay] tension and that in turn in a function of Forestay length. There are also, secondary, mast bend consideration, more so with the 49er and XX. And again there are tertiary considerations, also with the 49er and XX re spinnaker loads! A 49er has a Forestay of approx. 6500mm, a XX about 5250mm and a 29er approx 4700mm. We also know “empirically¹” that a 49er F/Stay tension is going to be between 26 (0-5knts) -> 33 (25 & above). We also know empirically that a 29er’s tension is going to be between 22 (0-5) -> 25 (25 & above). School is out on the XX but its going to be somewhere in between 25-31 (at a guess)! (FYI, we are talking numbers on a Loos Gauge, 22 = 130kgs, 24 = 150kgs, 26 = 170kgs, 28 = 190kgs 30 = 220kgs and 32 = 250kgs) A far smarter man than I will work out a formula, and it will have a square (to the power of 2) or a cube (to the power of 3) and will have a J factor in there also, “as it should” because its all about F/Stay sag. Sailmaker’s also empirically know that it’s foolish to assume that a F/Stay wont sag, it is infact impossible. So they cut “hollow” into the jib luff to compensate for the sag in exactly the same way as they cut luff round into the main to compensate for the mast bend.

  • 420 Tuning Hints
    420 Tuning suggestions College of Charleston 2012 Boat Setup on land: 1) Before sailing check that your shroud pin/ring dings are taped and secure, your tiller extension universal is solid, there’s no wiggle in your pintles and your hiking straps knots secure. 2) Tie your main halyard to the head of your main with a figure eight through the headboard grommet and then a half hitch back around the halyard. (see picture) 3) Hoist your jib and tension the rig tightly by placing a foot on the bow and pulling on the head stay while your team mate tensions the jib halyard. Don’t be afraid to over tension at this point as you’ll double check and most likely reset the tension once on the water. It’s easier to loosen once sailing than to tighten it! 4) Hoist your main and tension the halyard tightly. Use the 2:1 purchase to sock it up tight to the top of the mast. Again, it’s much easier to set it up tight on the dock than to rehoist once sailing! Set up on the water, before the start: 1) Trim your sails and head upwind. 2) Watch/study your leeward shroud as it is your guide to proper rig tension (through jib halyard tension). 3) Ideally the leeward shroud will just start to slacken to the point a slight wiggle (not more than ½”) is visible when the main is sheeted to maximum trim for the breeze/conditions at that time. Note: The advantage of using the “leeward shroud wiggle” is that you can gauge the amount of tension based on a given condition.

  • Effects of Educational Games on Sight Word Reading Achievement and Student Motivation
    Journal of Language and Literacy Education Vol. 13 Issue 2—Fall 2017 Effects of Educational Games on Sight Word Reading Achievement and Student Motivation Justine M. Gibbon, Stacy Duffield, Jeanette Hoffman, & Justin J. Wageman Abstract: Nine first-grade children at risk for reading failure were selected to participate in remedial reading interventions. These first-grade students scored below benchmark target and grade level expectancies on measures of early reading skills, including AIMSweb Nonsense Word Fluency and Northwest Evaluation Association Measures of Academic Progress (NWEA MAP ) for Primary Reading, or received a teacher referral based on oral reading fluency scores. Interventions occurred four times a week for 11 weeks, and included 10 minutes of direct phonemic awareness instruction and& 10 minutes of sight word games. Data were collected on students’ oral reading fluency, sight word identification, and motivation to read. Students were found to be more engaged and voiced a preference for sight word card and board games over the tablet apps. Results indicated that games as interventions can accelerate sight word learning and are highly effective for sight word achievement in first-grade students when combined with direct instruction on phonemic awareness. The participants improved at a rate double that of previously studied, remedial first-grade students. Results also indicated that intervention games in remedial reading programs have a direct impact on student engagement, but not necessarily on a student’s self-concept as a reader. Keywords: at risk, beginning reader, sight words, sight word games, motivation Justine M. Gibbon is a Title 1 Reading Teacher at Kindred, North Dakota.

    2008 INTERNATIONAL OK DINGHY CLASS RULES O K D I A Authority*: International Sailing Federation * The International Sailing Federation (ISAF) is not a National Authority (NA). 1. GENERAL 1.1 The OK Dinghy is a one-design class. The intention of these rules is to ensure that the boats are as alike as possible in all respects affecting performance. However, within these rules, variations in the construction of the boat are permitted. 1.2 The official language of the class is English, and in the event of dispute over interpretation the English text shall prevail. 1.3 These rules are complementary to the plans, measurement form and measurement diagram. Any interpretation shall be made by the ISAF which shall consult the OK Dinghy International Association (OKDIA). 1.4 In the event of discrepancy between these rules, the measurement form, the measurement diagram and/or the plans the matter shall be referred to the ISAF. 1.5 All boats shall be built in accordance with the class rules and measurement form as issued by the ISAF. 1.6 In countries where there is no National Authority (NA) or the NA does not wish to administer the class, its functions as stated in these class rules shall be carried out by OKDIA or its delegated representatives (National Associations). Where the NA has delegated the administration of the class to the National Association the words "National OK Dinghy Association" replace the words "National Authority" in the following rules. 1.7 Neither the ISAF nor OKDIA accept any legal responsibility in respect of these rules and/or the plans or any claim arising therefrom.

  • TOPCAT - Tool for Operations on Catalogues and Tables
    TOPCAT - Tool for OPerations on Catalogues And Tables Version 4.8-1 Starlink User Note253 Mark Taylor 10 June 2021 Abstract TOPCAT is an interactive graphical viewer and editor for tabular data. It has been designed for use with astronomical tables such as object catalogues, but is not restricted to astronomical applications. It understands a number of different astronomically important formats, and more formats can be added. It is designed to cope well with large tables; a million rows by a hundred columns should not present a problem even with modest memory and CPU resources. It offers a variety of ways to view and analyse the data, including a browser for the cell data themselves, viewers for information about table and column metadata, tools for joining tables using flexible matching algorithms, and extensive 2- and 3-d visualisation facilities. Using a powerful and extensible Java-based expression language new columns can be defined and row subsets selected for separate analysis. Selecting a row can be configured to trigger an action, for instance displaying an image of the catalogue object in an external viewer. Table data and metadata can be edited and the resulting modified table can be written out in a wide range of output formats. A number of options are provided for loading data from external sources, including Virtual Observatory (VO) services, thus providing a gateway to many remote archives of astronomical data. It can also interoperate with other desktop tools using the SAMP protocol. TOPCAT is written in pure Java and is available under the GNU General Public Licence.
