We had one of their rigid boom vangs installed, partially to make the topping lift
less of a necessity.
The vang works beautifully, but it doesn't have quite enough lift
to handle both the flaked main and the cover.
I sent a short e-mail asking them if there is some adjustment I can make or if I should upgrade to the next size vang. I come back from our 10-day holiday cruise
and find an e-mail from them asking for our mailing address. They will send two extra springs, no charge.
and a great product !
