Re: Westland Semi-Custom Covers
Yes, I was planning to use it for trailering too, but very infrequently.
Any trailering around 55 mph and greater will rip a loose fitting cover into shreds.
Order one and see how it fits you can always return it. But if the other posters said Westland brand didn't fit their their boats I wouldn't waste the postage back and forth.
I'd check out the Carver brand that the other poster had a good fit with. I have a Westland Sunbrella Bimini and the Westland frame snapped in have. . . China stuff!
But the Sunbrella fabric is tops for Biminis and enclosures. Others here will disagree not to use Sunbrella for trailering. I go by what my custom canvas shop whose been making covers for 35 years. He said Sunbrella stretches! He made me my custom trailer cover for $500 and the fabric was Top Gun. This is great stuff, has a slight rubberized feel to it and cleans up great. The Top Gun was the same price as the Sunbrella.
If you get the Westland brand get the Sharkskin over the Sunbrella. I know Sunbrella stretches. I'd call their cus support and ask if Sharkskin stretches. Sharkskin is less expensive too.
If you go with semi custom by a snap kit. The kit comes with a little punch to lock on the snaps. Any slack on the semi custom just put a snap on the cover and the boat so there is no flapping of the fabric "at all".
