With the Honwave T30-AE there is a space below the aluminium floor between it and the inflatable keel.
Tricky to pump water out of this space. There is a hole in the ali at the bow, but the inflatable keel is hard against this when inflated.
At the back there is a gap in the middle and at each corner, between the ali and the transom / tubes.
The gaps are small. I found this pump has a thin tube (I think it’s for getting oil out of a car engine via the dipstick hole.)

Using that tube via the supplied adapter onto the red tube got my boat as dry as the Arizona desert - though as they say over there, YMMV - your mileage may vary.
For me - best £11.99 I spent recently.
