271RE: [Holder12] inner hull drain hole

your boat doesn't have one I'd suggest adding one. ( Ronstan 295 or an
equivalent type drain plug )
The hull must have a vent hole somewhere. This would be a 1/16" hole -
probably behind a fitting or the name-plate. I haven't looked, but this hole
has to exist to allow the hull to equalize with the outside atmosphere so
the hull doesn't split a seam in hot weather. On the other hand, your
friend's problem sounds more like a leak. It could be at the hiking strap
mounts, mast step, daggerboard trunk, cockpit drain sleeve, or deck-to-hull
seam - somewhere a lot of water is present during sailing.
To find a leak find the inner hull drain plug. Gently apply air pressure by
blowing at the hole using a vacuum cleaner exhaust function. DO NOT
pressurize the hull by holding the nozzle against the drain hole - you WILL
blow apart the hull seams. While blowing air at the drain hole have someone
spray soapy water at all the likely spots. Look for bubbles.
Oh yeah - with that much water getting in it would be very prudent to
install an inspection port and dry out the inner hull before the floatation
gets waterlogged or the hull starts to delaminate.
