<p>Well you'll have a huge ammount of air locked up in there under the sun and the stars. That air will expand and contract every day, that means water INSIDE your beam that cannot get out. The designer specifies a vent hole with a breather tube in station 6 to vent the sealed buoyancy compartments under the floors, these are under water and away from the sun (so relatively stable temps) and if the designer thinks they need venting then we can imagine what will be the case with the beams which…</p>

<p>Just curious if anyone has any follow up on this? Would be interested to know if you have had any issues or wear and tear on your beams from either having drain holes in the end caps or having them sealed. Been a few years since it was discussed, so seems a good time to ask about longevity either way.</p>

Yes! I Think so. Last year I made two crossbeams on this way, with no holes, for another 25' design. The old was take off just because in some parts of attachment this develop rot.<br />
Tiki 30' is (stranger way) the single one Wharram cat with box crossbeams. All other designs is laminated wood or plancked wood.<br />
If I build a new Tiki 30' I will recommend and assemble "I" (or "H") cross section as on my Tiki 21'.<br />
Right now I begining to build a Tiki version with 34', but I'll use the combination "H"…

good luck, Ralf.<br />
