This tutorial is brought to you by sailrite. in this tutorial tutorial we will show you every step required to make a canvas or vinyl bimini top for a powerboat. The boat we will use demonstrate the process is a Maxum 2900 SCR powerboat. The procedures outlined in this tutorial will also work for sailboats. We will be working with a boat that already has a tubing frame erected. Lets get started. Here is the original bimini. As you can see it is rather loose fitting. It was designed.
By laying two panels together and a seam running from bow to stern. For shape the seamstress inserted darts on both the starboard and port sides. Our bimini will be much tighter and will have panels that are sewn together along the top of each bow with seams going from starboard to port. The advantage is a tighter and better form fitting bimini top, the disadvantage is the extra fabric that is required, but.
The extra few yards is in our opinion well worth it. How much fabric will you need and what width fabric should you use? Because we will have individual panels between each bow and bows typically are never more than 42 apart a 46 width fabric is perfect. To calculate the amount of fabric required simply measure from mount position to mounting position from starboard to port then multiply that.
Amount by 1.6 for each bow section (a single panel will be made between each bow). So for this boat we measured 87 from mounting positions. Multiply that by 1.6 equals 1′.2 inches. We have 3 panels for our 4 bow bimini, as the radar arch serves as our 4th bow, so multiply that figure by 3 then divide by 36. So we will need to order 12 yards of 46 width Sunbrella Marine Grade fabric from Sailrite.
Ok, i am sure some of you are saying that is a lot of fabric for only 3 panels on a bimini. So, in an effort to show you why lets show all the patterns and panels that are first required for a 3 bow bimini. As you can see each panel or pattern has curved edges and the sleeves are curved it will take much more fabric than just a straight edge rectangle would have taken. Now lets look at a 4 bow bimini.
Layup, this is the bimini we are building for this project tutorial and it does require 12 yards. A full materials list and the tools we used will be found at the end of this tutorial. To prep for patterning be sure the frame is uniform from side to side. Take a few measurements on one side then compare that with the opposite side, make modifications where needed to ensure that the frame is horizontal and all bows are as uniform as possible. Then.
Check to be sure all set screws are snug. after that we are ready to start patterning. Lets get started and show you how to make your own bimini. Since our old bimini top is installed and the frame and we are using rigid supports for this frame all we have to do is secure any frame that will move once the old cover is removed. For this bimini that is only the intermediate bow. We will use 3M Filament Strapping tape to secure this bow so we can.
Pattern without it moving. if your bimini top fabric is missing and you do not have rigid supports but instead have webbing straps you will need to use this tape to secure all bows where you want them before patterning. You can run the tape to various locations on the boat to accomplish a firm sturdy frame position. Since we have an old bimini top and we like where the skirt edge falls (that is the outside.
How to Make Enclosure Side Curtains
This tutorial is brought to you by sailrite. visit sailrite for all your project supplies, tools and instructions. This tutorial tutorial will show the steps required to make your own side curtain enclosure panels. Every detail from patterning, sewing, and installing zippers and fasteners will be shown. Making your own enclosure curtains may save you thousands compared to having a canvas shop to do it. Its not as difficult as it looks, especially after watching this tutorial. Purchase all the supplies needed to make enclosure.
Curtains at sailrite. Lets get started To attach our side curtain we will be using a zipper since our bimini top is made from fabric. If your top is a hard top you may want to use awning track and rope or fasteners. Installing awning track will be covered in our How to Make an Enclosure Aft Curtain tutorial coming soon. To sew on the zipper the bimini will need to be removed. Prior to its.
Removal we need to mark the appropriate stop and start locations for the zipper or zippers. Typically the zipper should stop about an inch or two away from the frame. This makes it easier to insert the zipper starter pin into the starter box when installing the side curtain. We have already finished the side curtain on the port side, here you can see the end of the zipper which stops about 1 inch away from the radar arch. Be sure to mark these start and stop locations on both the starboard and port sides of the bimini.
Now the bimini can be removed and taken to the sewing table. this finished zipper needs to be the correct length or longer. Here Angela is checking to be sure the zipper is long enough to be used all along the side of the bimini. She then flips the zipper to the underside and will apply a double sided tape called seamstick for canvas to the flange of the zipper. This seamstick is a inch width and is perfect for zipper applications because it is not so wide that the glue comes too.
Close to the teeth of the zipper. the seamstick will temporarily hold the zipper in place so we can sew it down perfectly. The zipper has been separated and we will baste the side which has the starter post or pin to the bimini top. Why? Well, when the side curtain is removed we do not want the slider to left on the top but rather on the curtain so it does not flop around in the wind. We are basting the zipper so the edge of the flange is about a half inch away from the facing strip that has been sewn to.
The side of the bimini. the distance from the edge is not too important, except that you want the curtain to tuck under the biminis edge to keep the weather away from the zipper. This finished zipper is too long so we will cut it to size with scissors at our stop mark. We recommend using YKK 10 Finished Vislon zippers from Sailrite. Take the left over zipper and match it up with the opposite side (the side with the slider and starter box). Cut the opposite side of the zippers end off so the length of zipper is exactly the same.
As what has been basted on the top. be sure to cut the end with the stop and not the starter box. Next cut some 1 binding to a size so it can wrap around the zippers end to make a zipper stop. Then begin sewing the zipper down starting at this binding zipper stop end. Keep the stitch about an 1/8 away or more from the zippers teeth to aid in future zipping and unzipping of the slider. The stitch length should be about 6mm in length.
We are sewing this project with a sailrite ultrafeed sewing machine. this is a heavy duty portable sewing machine that performs great for a job like this and is cost effective. In fact a single full enclosure job like this will easily pay for the machine and more. As is customary when you begin sewing and end sewing do some reversing to lock the stitch in place. Place a stop on the opposite side of the zipper that will be used on the side curtain.
