Sure, but if the main's down, then you can put the halyard on the end of the boom and use that to take the weight (and take some of the bounce out).
Of course, tie it to an arch, clip the main halyard back, drop the boom, or even just restrain the boom from moving side to side.
The key point is not to rely on the strut in such conditions. A spare main halyard is also a must offshore IMHO.
