Islander Catamaran

The Islander catamarans goal is to be large enough and capable enough to take a couple on long trips to remote Islands comfortably. (It is as big as it can be and still towed home for storage, other wise it would have been built at 30 feet just like the boat that inspired it. See here if you are looking for a larger boat. Plans are now free! )  It has stand up head room in the center hulls, a galley, a head with sit down or outside shower and room for a double bunk with a “pop top” which permits sitting headroom there as well. It carries a fair amount of water and supplies and was built with open water passages of 50 miles or more in mind. A lot of thought and time has gone into the design but the build time has been very low for this size of boat due to the way it is constructed. The priority was not very high to finish this project due to having a job and  keeping me with something to do in the garage. Well, it is at the stage that it can be taken to the water and enjoyed now although not quite finished and the plans are completed so that if anyone wants they can build one if they have knowledge of the basics of boat building. Photo above was progress as of 7-17-13 and a build time of less than 1 month of part time work. Plans released on 4-20-2015 and cost $25 instance download only. This is done because RagWing is a hobby for me and not a full time business and it will stay that way as I near retirement. Whatever money is made goes back into RagWing to help pay for past projects and keep the site up. It is my hope to become a Non-Profit 401C org. For more current photos see the photo link button and I will release more pictures as time permits and they are available.

Hull Numbers

You may request a hull number for your RagWing Islander as soon as it goes 3 D. You do not have to wait until it is completely done. Hull numbers will be issued in the order that the requests are received. So the sooner you get yours going the lower number you will get. Please supply the following with your hull number request: A photo of your hull along with your name, address and other contact information. When possible it would be nice to have the builder in the photo. I will let you know your hull number by email. Specific hull numbers cannot be requested. Hull numbers are to keep a good count of how many boats are being finished. You do not have to request a hull number nor do you need a hull number. It is just fun to see where the craft are being built and where.
