well, you have a reply microburst.

We drove into 3 bursts in Florida without incident. Solstice on van roof resting on the standard foam hull pads available from Campmor, NRS, REI.

Bow tied to 3 - front 2 sides - eye bolts on bumper, stern tied to 2 eyebolts on bumper.

Side forces were taken up with the Gullliver Method.

Using small diameter cord aft front hatch, aft rear hatch were clove hitched around hull to small eyebolts moutned into drip rail.

The cord probably 1/8th was run over the hull fore and aft cockpit coaming.

Drill baby drill. Use marine chromed eyebolt hardware and sealant.

Now using Quick n Easy rack supports with steel strap bolted under 2x4 cross members. If you visit lumber country buy their best n bring it home. The QnE rack allows for an outrigger with wind stops for easy side loading as in log cabin construction lever it up. But the pads are still under the yak held onto 2x4 with 1x stops.
