It is a sit-on-top kayak with a difference. Our Kayak allows the user to view the majestic beauty not only around them but bellow them. This is done by incorporating an acrylic glass window between the user's legs so that they can view the world bellow. Sit-on-top kayaks were developed in the past for lower end recreational users. However have now evolved into one of the highest selling personal non powered water craft. In fact 7 out of 10 kayaks sold are sit-on-tops. The growth in popularity is owed too many factors. The following is a list of key factors; Price: These crafts are much cheaper as made from plastics in mass numbers Ease of Use: If the user falls out of the craft it is very simple to jump back on, unlike with conversional kayaks were this is an impossible feet. This is why sit-on-tops are popular with fishing and SUCUBA diving users. This is because these users require to leave and enter the craft constantly, change seating position, and access storage hatches. Functionality: Sit-on-tops may be used for a variety of applications. In rapids, the bay, rivers, cave exploring, lakes, surf, almost any application thinkable. ...read more.

Conclusion

Optimization of Design Layout For the following techniques applied to our process flow, some assumptions should be pointed out. Upon the completion of any individual part, it is stored in dispatch ready to be used. In our actual factory this is not the case, as parts will be stored as WIP were they will be needed next. Area Key Fig 8.2 Operation Sequence Fig 8.3 String Diagram R A B C D E F G H Fig10.1 From this we see that there is no back tracking, so from a multi-column process chart we would find that this process is 100% efficient. For this reason it was chosen not to do a multi-column process chart. From-To Chart Fig 10.2 Initial From to chart Fig 10.3 Fig 10.4 Fig 10.5 From Fig 10.4 and Fig 10.5 it is easy to find the efficiency of the alphabetical layout. Efficiency = (411/3220) x 100 = 12.7% From Fig 10.5 it is shown that G needs to be closer to D, and D is required closer to R to dramatically improve the efficiency. Fig 10.6 With the rearrangement of area distances there are both improvement in the larger weighted items, and some backtracking for the less weighted items. It is now possible to find the efficiency of the second From-To Chart (Fig 10.6) Efficiency = (411/1255) x 100 = 32.7% This is a huge saving in efficiency. N.B. Ocean view does not work on a production line type basis, so these optimization techniques do not have full relevance when used with processes such as ours. However from the from/to diagram we find the relative importance of having some of the major departments closer to each other. This was also shown on the Block Diagram analysis. Our design allows for this with superior materials handling equipment which almost makes all items have the same relative importance when relating to the table Fig 10.2. As this is the case we have chosen not to change our process or layout as it originally contained no backtracking. ...read more.

    Billet centres on multi-piece wheels, however, are common. Forging Unlike casting or billeting, forging uses intense heat and pressure to transform a slug of alloy material into the final shape of a wheel. Under this heat and pressure, the original grain structure of the stock material is forced from the centre of the wheel towards the outer edge.
