Boat Cover Modification? 210CC

[naipaulss2]

Can the semi-custom boat covers from IBoats 210cc ($240-260) be modified to fit under the ttop? I noticed several manuf i.e. Coversinc are recommending a cover that fits under the ttop.
Has anyone purchased a semi-custom fit cover and modified it in this way to save $$$?
Just Curious.

Not I personally, but that cover does look nice.
