I have made 4 cockpit covers and 2 dodgers for my boats over the years, including for my previously owned M 15. I have the following suggestions to make it easier. (I have trouble working with patterns, but if you don't, it is a great way to go as previously suggested.) 1. This can be done on any sewing machine with a # 18 needle. Although a machine, like those sold by Sail Rite make it easier. 2. Lay your material, the one you are going to use for your finished product, over the boom. 3. Clip it together where the longitudinal seams will go with spring clamps. (The seams should run port to starboard.) Leave material under the seams to sew it together.) 4. Using a stapler, staple the bottom edges where you want them. 5. When you go home, you can cut the extra material off and then sew. Pull the staples out as you are sewing. 6. For tie downs, make sure you use spur grommets. They won't tear the material in heavy winds. 7. Once you completed the basic "tent" , go to work at the front and back. (You can even get fancy and install "windows" and then make window covers for them.) Note: make sure you can easily enter enclosure from the inside, outside, dock, etc. 8. Again, use the clamps to set the material, and then use a stapler. 9. If the material bunches up because of curves, etc., staple in darts. I highly recommend The Complete Canvasworker's Guide by Jim Grant. I found it very helpful. I hope this makes sense.
