Different pole arrangement from trailer cover to canvas covers if thats what you mean. The canvas use the "T" pole with the horizontal pole held in place fore and aft by loops sewn into the canvas. Then there is a snap in the center - directly over the vertical pole to keep it situated. There are two poles one in the bow and another in the cockpit for the 210.
The trailer cover relies on two poles as well (one in the bow and another in the cockpit) - they are adjustable in hieght. On top of each pole is a plastic dish like a small tea cup-saucer. There are 3 straps attatched to each of the saucers on each of the pole tops.
1 strap fixes the two pole tops together from cockpit to bow seat - over the windshield.
The 2 straps remaining on the bow pole loop over each bow cleat before the cover is pulled on (the cover has reinforced slits that the cleats fit through).
The 2 straps remaining on the cockpit pole each loop over a port/starboard aft cleat before the cover is pulled on (the cover has reinforced slits that the cleats fit through).
The cover is then hooked over the bow and pulled back with the velcro slits (if applicable) in the sides fitting around the tower legs and finally pulled down over the swim platform and all the way around over the waistline or rub strip.
There is a horizontal strap sewn in the base of the cover - to tighten around the the perimeter of the boat below the waistline with a ratchet tightener at the back (over the outdrive) in a little zip-pouch that should prevent damage from banging (if you make it a point to always keep it zipped up).
I notice that the aft pole straps dig into the sun-pad and I worry about tearing or marking so they get a scrap of cardboard on each side / point of contact.
I have heard of people using lengths of copper pipe insulation - that grey foam for the windshield header and will probably start doing the same. It costs almost nothing at hardware stores. Hadn't occured to me to try to use it on the canvas poles like mentioned above - but I hadn't noticed any wear there yet. Better take a look - the canvas is pricey.
One thing not mentioned is the bimini. Mine is integrated into the tower (I don't have the forward arch) and when the boat was brand new and towed home (16hrs on the highway) for some reason the bimini bows had jiggled together and subsequently wore a few small holes through the canvas. I would reccomend anyone with a top of any sort check thier biminis are not doing the same; that they are carefully folded and strapped nice and snug before putting on the boot to prevent this from happening. A lot of us do not use these small tops all the time so it would be a drag to open it up and finding it with a bunch of holes wore in it. Hardware stores carry these cool velcro straps for a couple of bucks which is what I now use before I zip the boot over the top. Seems to have worked out well so far.

Geez Suishi you went with a new cover and the fancy forward arch. Whew - pricey. But man, what a difference. Beautiful.
