While the event does not meet the accident/incident reporting requirements of NTSB; this report may be of some value to other pilots.Aventura amphibious (flying boat) 2-seat single engine piston EAB in pusher prop configuration; with electric repositionable landing gear.After water-landing in a local pond; I returned to the airport area. Upon announcing on CTAF my plan to enter the downwind another pilot offered to extend his takeoff leg prior to entering a crosswind and downwind. I (unnecessarily) expedited my pattern to minimize inconvenience to the other pilot; and in the process failed to lower my landing gear (resulting in far more inconvenience). My aircraft's fiberglass hull skidded across the runway surface; leaving a line of white dust. This incident was a direct result of my failure to use the landing checklist; a checklist that is committed to memory and also printed on my panel! After coming to a stop and realizing what had happened; I notified pilots in the air via CTAF to not land on this runway and asked the FBO for assistance. I exited the aircraft to assess damage to the aircraft and to determine how to best to exit the runway.Damage to the aircraft was minimal and the aircraft is in a condition for safe flight. I was asked not to move the aircraft until given the go-ahead from the FSDO. During the approximately 30-45 minute wait; I walked the runway to verify that there was no damage to the runway surface and to verify that the incident had not deposited any FOD. FBO staff did the same.Upon receiving permission to exit the runway; two people lifted one side of the aircraft by pushing up on a wing strut while I manually locked a main gear leg into place. We did the same on the other side. I then started the engine and taxied off the runway. This process took approximately two minutes.I am still relatively new to having to worry about landing gear position (being used to fixed gear) and apparently my brain was working on autopilot and perhaps also distracted by trying to expedite my landing. The embarrassment and repair effort will ensure that I use the checklist in the future.
