I am going to have a cockpit cover made for the 320, basic plan is to use Sunbrella and running the cover from front edge of deck where windscreen would start (if I had windscreen/windshield) to cover dash area and back to top edge of transom/swim platform covering sundeck. Hoping to locate black anodized nickel for snaps and fastners to hide on black areas of hull and would like to minimize the number of snaps. One shop stated a fastners every 8-10" was typical but with the cockpit being fairly small I'd like to see if 14-16" inches will be enough to keep the cover tight. Really hate drilling holes for the snaps so would love alternative ideas on this.

Any suggestions from those that have had cockpit covers on things to do or even "oh sh33t" don't do ________. Is any type of backing material reccomended for the areas of cover that contact the bolsters or sundeck upholstery? Guesstimating it will take around 9 or 10 yards of canvass what ballpark pricing should be expected? $250-300 in canvass so triple that to cover all time and materials??

Finally got the cockpit interior redone and need to keep it clean now. 😀

Thanks in advance,
Rick

1. 14" to 16" snap spacing is pretty typical and will work fine. You need some sort of snap or turnbuckle to keep the fabric tight so as not to puddle water. There's a reason that the vast majority of covers attach this way instead of cinching around the rub rail or bungees etc
2 When I had my 320, rain would always work its way into engine compartment through the 2 transom air vents. I'd suggest extending some flaps on the cockpit cover to cover up the air vents to keep the water out.
3. Install backing material anywhere the cover contacts another surface and especially where it rolls over the cockpit edges. I've seen vinyl generally used or another layer of Sunbrella. The covers wear through on contact points much faster than via old age failure.
4. Get the most sun and weather resistant thread available - the sunbrella fabric usually outlasts the thread.
5. My 320 used a single support pole. My 390 uses two. I think two poles do a better job - less stress on the cover and better drainage.
6. No idea on the cost as it greatly varies

Thanks and great tip on the transom air vents!

Yep, also make sure it covers your side engine air ducts. Two poles for sure on a 320.
