Mosquito Screens – Check!

Finished in the Aft Stateroom

I really have no sewing background at all!  But somehow… give a girl a Sailrite and she’ll make you… well, whatever you want!  This time, it’s mosquito screens/sunshade for the overhead hatches!

Hatch open – the shade blocks the direct sun but lets air in

I purchased so much of the Coolaroo Sunshade fabric for my deck awning project that I had plenty left over.  I had planned to sew some mosquito screens for the hatches, but hadn’t bought any fabric for that yet.  I was so happy with the sunshade stuff, I decided that it would serve as dual purpose fabric for the hatches, sunshades AND mosquito proofing!

A Facebook friend told me about a product produced by Velcro called Velstick.  I purchased the loop side (in retrospect, I should have got the hook side) and we mounted it to the ceiling using small brass screws.

Also, I couldn’t find it in white, which would be my preferred color.

The companionway was going to be a bit more involved as the doorway wasn’t square.  I’ll save that one for last.

Don’t know what we would do without the cutting board…

The Velstick was VERY easy to work with.  I used a utility knife to score a line on the back, then bent the stick to break on the line.  Then I cut the fabric side with the utility knife.  Very easy and no mess.

The Velstick was in place for days while my mind worked over the plan for sewing the screens.  Finally, while we were at the dock in Rockport, TX, I got brave and dove in.

My workspace was a bit small and the Coolaroo fabric is kind of crawly, but I only ruined one square before I got it right.  I cut two identical pieces as two of our hatches were the same.

I found that I got a nice square piece by folding the fabric over in half and measuring half of the width, then folding it the other way and cutting the length.

There is no way to do an exact “how to” for a project like this, since everyone’s hatches are different. We have one hatch that is too close to a wall for us to mount the Velstik like the others.  We ended up mounting it on the wood and following the Velstick with the fabric.  It turned out great and still forms a positive seal against mosquitoes.

Turn both edges at the corners before sewing

The sewing part, I just kind of “did it”.  I started with cutting the fabric with a one inch hem allowance.  I turned each edge over 1/2 inch and placed a strip of regular 1 inch hook velcro on one side, and a strip of white webbing material on the other side.  I turned and aligned the pieces as I sewed.

I had planned on sewing in a loop of webbing on the corners to use as “pulls” to remove the covers, but when I got to the first corner, I just looped it over and continued sewing down the next side.  It just takes a little thought to make sure that the hook strips are continuous and not cover them with the webbing at any point.

One on each of two ends  going the same direction

I also thought about storage.  Maybe I could sew in strings to tie the rolled up covers.  In the end, I sewed a short strip of regular loop Velcro to the top sides of one end…

If only the Velstick were white…

We can just roll the cover to one end and it stays put.  We don’t have to find a storage place for them unless we don’t plan to use them for a while.

As I said before, I saved the more difficult part for last… I figured I would get all of my mistakes out of the way on the easier hatches.  Well that didn’t work out… I sewed one velcro strip on upside down and had to rip out the entire edge… but hey!  That’s OK…

The seam across the middle is the two parts velcro’d together

My original plan was to make one continuous piece to cover the companionway.  I ended up doing it in two, first thinking that it would be easier… not, and secondly, I thought it would be nice to be able to remove one piece to get out, without removing the whole thing.

It turned out well but I did miscalculate one thing.  I added a 1 inch allowance for the velcro in the middle there on both pieces.  I should only have allowed extra on one of the parts which would fold down onto the other.  Instead of ripping out the entire bottom edge, we just affixed a second strip of Velstick below the bottom edge and it stuck right on.

So that’s it!  Somehow I managed to “wing it” and get the job done.  We are VERY happy with the outcome.  I think the covers will be really nice on hot days when we don’t want the sun bearing down on us… and for sure they provide an impenetrable barrier against bugs, maybe even no-see-ums.

  1. An awesome site, thanks. I have made most of the covers for our boat – except for the Big ones – boom tent and bimini.
    Lots of good tips and tricks for me to use when I get back to the boat.

    1. Hi Sue,
      Thanks for visiting Seamless Sailor. Glad this collection is useful.
      PS I haven’t had Internet access for awhile. Sorry this response is so late.

  2. I am looking for some of this Velstick stuff for a camper project I’m in the middle of. Where were you able to get yours? I’ve found it for a reasonable price but the shipping kills. Thank you!

    1. Hi Bill, Tammy Swart wrote that post on mosquito screens so I sent her a note asking her where she got the Velstick. I know I found it online. I didn’t look at shipping costs though. More soon I hope, Annette
