Literal Meaning
सत्याप-पाश-रूप-वीणा-तूल-श्लोक-सेना-लोम-त्वच-वर्म-वर्ण-चूर्ण-चुरादिभ्यः णिच्

align tumbi connected upto rope rope upto javeline, flow outwarded rope, wave inward push untill, tumbi outward (floating tumbi) sand/soft, hand held from javeline (in)sand, into aligned pull untill from sand fish, wave+tumbi repeat, wave superior inside/fish, wave superior push, repeat outward push, repeat outward flow untill roll inward connects steady tight; push inward again

(if) water outward rope, (then) wave pushes untill tumbi outward loosens; (so)
align tumbi connected upto rope rope upto javeline,
javeline in sand from hand held to align pull until inside from sand,
wavering tumbi repeat, inside superior wave, repeat outward push, repeat outward flow till roll inward connects verticle/standing tight; push outward repeat

Now we are talking of floating tumbi. word used is outward and not outside because outside used to mean abpve water and here we are referring to rope that dangles outward - or pushes tumbi outward when there is flow:
If water outward rope then wave pushes will loosen floating tumbi. To prevent/minimize this, align tumbi connected up to rope, cope upto jave line, adjust javeline in sand till pull aligns inside. floating tumbi should pop in and out of wave - inside with superior wave as superior wave pushes, again pushed up at (when) water flows out and stand tight vertically till wave tolls inward and pushes inward again - i.e. till tumbi moves inward and outward - shoreward and seaward with waves and gets submerged when there is superior wave. It is assumed that -Do all this when there is low tide.
