Re your tri:bo: : when I tried to establish the semantic extent of the putative *d/tran,W- root,
http://tech.groups.yahoo.com/group/cybalist/message/61626
besides the categories of "pull/carry/drive", "wooden pole", "crew member" and "crew", one of "tremble" also came up (Pokorny:
'dhreugh- ,zittern, (sich) schütteln, einschrumpfen'.
...
1. ter- ,zappeln, zittern'?
Ai. taralá- ,zitternd, zuckend, unstet'; alb. tartal/is ,zapple' (aus redupl. *tar-tar-). ...; 481;
Erweiterungen: tr-em-, tr-es- (Kombinationsform *trems-), tr-ep-.
...
terk-, trek- (tork-, trok-) ,drehen', wohl Erweiterung von 3. ter- ,reiben, drehend reiben'.
...
trem-, trems- (kontaminiert mit tres-) ,trippeln, trampeln' und ,zittern' (dieselbe Doppelbed. bei trep-).
...
1. trep- ,trippeln, trampeln, treten'; tropo-s, tropa: ,Weg'.
...
tres-, ters- (*teres-) ,zittern'.')

which I didn't know how to fit into this water transport framework, so I left it out. But maybe there is a way:

If tri:bo: is part of this complex, we must consider the possibility of it being a loan.
