Would I do it ... no. The older I get, the more I like to mix speed, comfort & safety
There is a good chance
that the right dingy, sailed sensibly, would make it ... but it would be safer in a hull
a bit like one of those things trans-ocean rowers use ...
Nonetheless, modern boats and technologies make it much easier than the guys below had it:
Frank Dye sailed the Wayfarer "Wanderer" (15'10", circa 200 kilos) from UK to Iceland
and UK to Norway
. He had it specially set up, but still (by memory) said its limits were Force 8. So a moderately light, unballasted dingy is a dubious proposition ...

And David Blagden sailed "Willing Griffin", a cabin-topped version of the 19' Squib sailing dingy, completed the (solo) OSTAR Trans Atlantic against prevailing winds.
Hunter Boats History
Both these boats headed straight into pretty serious stuff and got through.
But it gets exciting cruising a Wayfarer when you are overtaking waves (something I survived when the UK PM's 30+' boat "Morning Cloud" went down a few miles away). Some things are best left to the follies and energies of youth.
