Oh sure, one might wish being that way…
In fact their boats were mostly flat bottom ones, intended to be fast coastal sailboats.
Their sails were rather effective downwind but very poor windward, then the slaves had to row…
Thanks to their flat bottoms they could easily go ashore doing "strandhugg" plunge & plunder and quickly runaway.
They used the creeks, inlets and coves found along the coasts to rest during their sailing, hence the name Viking, which is believed to originate from "Vik" a Swedish word that means creek, inlet, cove or gulf.
It's still unsure whether Leif Ericson had planed his sailing to N. America or just had drifted ashore there by a storm...
It's unknown whether it was a single trip (one way ticket) or there were several trips back and forth.

JAS stands for "Jakt, Attack & Spaning", which means hunt, attack & reconnaissance.
