I did a search of the forum but didn't quite find what I needed.
I am going to make a pontoon cover and want the best way to support the center with poles.
What seems to be the best /easiest way to accomplish this? I see some covers that have some sort of round disc on the outside of the cover, I assume this helps hold the pole on the inside in place.
Thanks in advance.
Bruce.
the disk you mention in called a vent so port it screws together to the cover and a support pole fit into the bottom of the vent , the cent heps the cover breathe . other ways to do a pole in a pad with a snap sewn ro the inside of the vober and a pole with a snap stud on the top of the pole , or a grommet in the cover and a pole with a tent pole tip in the grommet support pole can be bought that has a interchagable inner pole that adust the had a pointed tip on one end and a snap on the others

Thank you Mike.
To make it less likely for a pole to tip over. Is there one prefeered method over the other? I am thinking that the vent way would hold the pole for you while you are putting the cover on the boat.
Also, unrelated to the support pole, what is the best way to make the opening around the bimini poles? Just make a slit with it opening up where the pole goes through the cover? My plan is to put binding on the bottom of the cover so my thinking is to extend the binding up and down the slit for the bimini poles. I would make a flap, sewn under the cover with some velcro to keep the slit from flapping.
well with a breathable fabric like sunbrella a vent is really not necessary. ive seen the grommet type that the pole sticks in if the pole is not tight the wind can lift the cover off the pole and the pole walls over and now you have a bug funnel. so I don't like or use it, the sap tip snapped to the canvas if not up tight the wind can lift the cover and snaped on pole off the deck of the boat and its still ok the vent type could come out if it was low nut its unlilely its in there pretty good and it would be more difficult to come out so with the few extr buck of the vent the customer is sure to like it. but the snap pole I use the most
I use the boat vent II on all my covers and for poles I have a set of adjustable poles to use while I build the cover to determine exact size then I cut the final poles from 1/2 electric conduit and put rubber chair stops on the floor end. Adjustable poles tend to slip with the weight of snow.
As far as cutting the holes, I have a small cup that is just the right size that I trace around and then cut the hole with my seam ripper or scissors. Also, I don't use sunbrella for pontoon covers, but typically Aqualon or Top Gun.
I never recommended a mooring cover for the winter snow . I once saw a snap on cockpit cover with snow on it and the windshield glass broke , it was a older 80s bayliner
On the subject of cover support, several of my customers will add poles to the cover, especially when the boat is exposed to year around weather. The poles they like are often more of a small frame with a base and top construction wider to distribute the load of the cover and any snow or pooling of moisture.
Their poles at the base or built as a cross and perhaps at the top shaped to the natural shape of the cover.
The load on a cover can really be heavy in the winter.
There can be other good ideas to gain cover support (pontoons of course).

There is special tool to cut the round hole, but at $50 unless your doing alot of them do as Tim and find/make yourself a jig the right size.I sew a 12" disc of Vintex (a.k.a Herculite,Sampson,Gladiator etc...) on the inside of the cover.

Up here , those of us who don't have a friend with a machine shed, build a ridgepole out of 2X4's and either shrink wrap or cover the boat with a cheap poly tarp. But!--there is always the guy who waits too long in the fall and mangles his convertible top or warps his windshield . That's why I'm afraid to half pattern boats. They are not usually isometric after a few years.
Another thing is how many poles to use. I typically use 3-4 on twenty foot and under and 4-5 on twenty up to twenty-five footers. I also do as Darren and stitch in a piece of 18oz GVC where every pole meets the cover.
We get up to a foot of snow once in a great while here, usually three or four inches and then it almost always melts before the next snow. Late last winter we got 13" of heavy wet snow and I seen a lot of older worn covers give up the ghost but everything that I had made in the last few years held up fine. I offer shrink wrap but most folks around here don't want the added expense.

You have any pictures of pontoon covers you have made with Top Gun? Every one I see is wrinkle city.

Here is one of my "wrinkle city" covers made from Top Gun.

Looks pretty darn good to me. I hate sewing Top Gun because it's virtually impossible to make a seam that doesn't gather the fabric. Luckily it hasn't been very popular in S. Florida. I really don't miss the canvas sewing. Vinyl is so much easier.

Thanks June,
I agree, the stuff is a pain to work with but it does last a long long time. I have also been using Harbor Time from Tri-Vantage. It is similar to Top Gun, 11oz, five year warranty etc. but cost a lot less and I think it is easier to work with.
I still prefer the Aqualon even though it's shiny surface makes wrinkles look worse, at 9.5oz it is manageable and the customer can take it off, fold it up and stuff it under a seat without the help of a couple of lumber jacks. :)
That one looks good.
Since the Top Gun is a little bit heavier than Sunbrella, is it ever an issue where people prefer the Sunbrella because its a bit lighter and easier to put on/off?

Where can I purchase a small amount of GVC for my reinforcement?
I have a Bayliner Rendezvous 26' deckboat. Last summer I made a new towing cover and I used 2 of those vents at the top of the poles. There very easy to install. I used to have only a grommet that the pole end stuck thru, but while towing the grommet would rip out. I ran across a new problem, maybe somebody could have an idea , RAIN WATER. Rain water accumulates on top of the cover between the rear vent and the stern rail and between the front vent and the front rail. It seems that placement of these poles are critical. Trying to find a solution. A drain hole, cross poles made of PVC. moving existing vents, or ?.
The poles Ive been getting have a plastic rounded spike type on one end to fit a grommet and a snap stud on the other end so you can use either. I make a extra wide full flat felled seam down the center and put them in that between the seams. Its in four layers and I havent had any callbacks doing it that way ,,,yet. lol dont wanna jinx myself.
