Narrative:
Event was a higher than normal speed, nose low, water touchdown in a constricting landing lane. On touchdown, aircraft violently yawed left, then right, then stabilized. Aircraft stopped 50+ yards from boat traffic (no damage to aircraft). Prior to incident, aircraft was passed by faster company aircraft proceeding to some destination. Subject aircraft landed 30 seconds after company in an adjacent (and interior) lane. Event was caused by my failure to 'slow down and let things improve' and/or to 'go around.' specifically: 1) had I done a 360 degree turn or other delaying maneuver to allow company to land and stop, I would have had all of lake to use, rather than 1/2 or less. 2) once committing to one landing lane, and noticing it was constricting (boat traffic at end crossing and/or closing in), instead of hurrying touchdown, I could have gone around.

Title: A DHC-2 FLOAT PLANE PLT LOSES CTL OF HIS ACFT DURING A HIGH SPD, NOSE LOW APCH AND LNDG THAT, AFTER STOPPING, CAME WITHIN 50 YARDS OF A PASSING BOAT AT LAKE UNION, WA.
Narrative: EVENT WAS A HIGHER THAN NORMAL SPD, NOSE LOW, WATER TOUCHDOWN IN A CONSTRICTING LNDG LANE. ON TOUCHDOWN, ACFT VIOLENTLY YAWED L, THEN R, THEN STABILIZED. ACFT STOPPED 50+ YARDS FROM BOAT TFC (NO DAMAGE TO ACFT). PRIOR TO INCIDENT, ACFT WAS PASSED BY FASTER COMPANY ACFT PROCEEDING TO SOME DEST. SUBJECT ACFT LANDED 30 SECONDS AFTER COMPANY IN AN ADJACENT (AND INTERIOR) LANE. EVENT WAS CAUSED BY MY FAILURE TO 'SLOW DOWN AND LET THINGS IMPROVE' AND/OR TO 'GO AROUND.' SPECIFICALLY: 1) HAD I DONE A 360 DEG TURN OR OTHER DELAYING MANEUVER TO ALLOW COMPANY TO LAND AND STOP, I WOULD HAVE HAD ALL OF LAKE TO USE, RATHER THAN 1/2 OR LESS. 2) ONCE COMMITTING TO ONE LNDG LANE, AND NOTICING IT WAS CONSTRICTING (BOAT TFC AT END XING AND/OR CLOSING IN), INSTEAD OF HURRYING TOUCHDOWN, I COULD HAVE GONE AROUND.
