Tent/awning off boom

I wish to make a tent/awning that is attached to either side of the boom and each side of the tent tied off to the stanchions.

Reason for this is to provide a sun barrier and a heat shield to the saloon - my cruising is all in HOT tropical areas.

The use of the tent would be for deployment when anchored up for a few days - obviously not while sailing.

Wondering how others have done this.

Someone locally suggested this type of aluminium profile so that the ripstop that is attached to a cord can be inserted into this profile thereby attaching the ripstop to the boom. I am a little hesitant to drill holes and rivet this profile to my boom....but it may well be the right way to do it.

Re: Tent/awning off boom

jim how is your sail attached to the boom. do you have a stack pack, lazy jacks, conventional cover.


installing and removing the shade would be a huge PITA IMO with that type of extrusion.


option 1. just drape the entire tarp across the entire boom ( won't work if you have stack/lazy jacks)
options2 install a 4-5 saddle eyes/ eye straps on each side of the boom so you can just clip/tie the shade to the boom at several points (downside is now you have something protruding from the boom)

option 3 if you have lazy jacks. clip the shade to your lazy jack legs.
option 4 on your shade cloth sew on some straps/clips so you can clip each half (port starboard) to each other through gaps in the lazy jacks
option 5 if you have a stack pack sew on clips so you can clip your shade to the stack pack...



i'm sure there are other ways to skin the cat, but thats what popped into my head right off the bat

I second Marc's suggestion. Just drape it over the boom and mainsail.

Re: Tent/awning off boom

You could have one side of a zipper sewn to the underside of the stackpack, and the other side sewn to the awning cloth. Then it's easy-peasy to just zip the shade cloth on.

Re: Tent/awning off boom

A zipper isn't a bad idea, but a bolt rope will be much sturdier and outlast a zipper.

It will come down to which is more important to you, aesthetics or functionality.


Edit: Jim, would use heavier material than ripstop if you want to really block heat and sun/UV.

Re: Tent/awning off boom

It is attached to the cloth to slide it into the track you originally posted. https://www.sailrite.com/Boltrope-5-...bricated-4-6oz

We use a bolt rope for our side enclosures and sun shades off of our bimini.

Re: Tent/awning off boom

I made a awning last year. I drape mine over the boom, but I can also do only one half simply by tying one end to the mast and the other to the end of the boom and stretch it tight.
I have lazy jacks, but it wraps around them sufficiently. I plan to modify it to add slots for the lazy jack's.

Re: Tent/awning off boom

jim...basedon your pic



something quick and and easy I'd make a rectangular shade for the one side with gromets that line up with your lazy jack lines, one of your shrouds and then several down the side to clip onto the life lines. you can get some spring clips


this would mean you don't have to modify your existing stack pack. downside is that you'll have to be pretty flexible if you leave the cockpit and try to go forward. sinc eyoud be ducking under the shade cloth at the life line level.


you could make a triangular one for the area in front of the mast. use you spinaker pole track to get your height. a clip on ech aft corner to clip onto a shroud and the a forward clip around the furled sail.


if yo made the shade cloth out of a water proof material then you could have it lower while its raining to be able to open the fwd hatches...

Re: Tent/awning off boom

I made my own awnings.

I used several pieces of 1.5" pvc pipe the width of the beam.

For the main, I had 4 of these. My the foot of my main was not very long, you could increase the pvc poles to 5 or 6 for your boat.

To the pvc, I attached an awning made from sunbrella, which I sewed myself using a cheap 'ole Walmart sewing machine and nylon thread, don't use cotton here. The awning was the lenght of the boom and the width of the beam. At the end each pvc location and the front and back center, I reinforced the fabric and I punched a brass ring thru' the fabric. The edges were all rolled over to a 3-ply thickness.

At each ring location I tied a lenght of 1/8" nylon rope.

The sides of the awning was attached to the lifelines, the front was attached to the mast and the back to the end of the boom.

The pvc will take a bit of a bend and arc over the boom.

Even in high winds, it never came off. Would flop around a bit, but stay put.

I made a similar awning in a triangular shape, with pvc poles that went over the foredeck. The front being tied to the bow pulpit and the rear to the mast.

When I went sailing, I simply rolled them up and lashed them to the stanchions.

Lasted for years and years.

Made a huge difference when anchored. The beauty being you can leave hatches open in the rain.

Even in the middle of summer, inside of boat was quite cool, with just a breeze coming thru' the hatches.

Re: Tent/awning off boom

I should add, I made the pvc poles a bit longer than the width of the awning. At the end of each pvc pole, I drilled a hole. The 1/8" nylon was led thru' this hole. THe holes being a bit wider than the fabric, allowed me to tension the 1/8" lines, so the awning remained nicely stretched out.
Once the 1.8" line was thru' the hole in the pvc, I tied the 1.8" line in a simple overhand knot right underneath the pvc pipe, so it wouldn't slide back out.

Good question.

The term showed up in nautical English in 1626. It's origin and history are unclear.

Best guess is that it refers to Old English c1000 boltas, arrows designed to be fired from a cross bow. And the reference is the linear shape of a cross bow bolt, in the same way as a ‘bolt of fabric’.
