Narrative:

At 1200 ft 4-5 mi out on VFR approach, controller called 2 aircraft as traffic. The first traffic called was further away (1 mi) and not on collision course. The second was called as 1/2 mi away. I looked for and found the first aircraft called, then looked for and found the second (closer) aircraft. I initiated a climb to evade the second aircraft. Without evasive action, a collision might have occurred. Both of the other aircraft were float planes, eastbound. Suggestions: controllers may be overworked. This traffic should have been called (from bright radar) sooner, the aircraft on a collision course should have been called first, steps should be taken to educate local float plane operators to stay further away from boeing field arrival path, and I wish there was a way to find and violate pilots who enter class B, C, D airspace without clearance.

Title: PLT OF A CESSNA 337 TOOK EVASIVE ACTION BY CLBING TO AVOID A FLOAT PLANE COMING IN THE OPPOSITE DIRECTION WHILE ON A VFR APCH IN CLASS D AIRSPACE.

Narrative: AT 1200 FT 4-5 MI OUT ON VFR APCH, CTLR CALLED 2 ACFT AS TFC. THE FIRST TFC CALLED WAS FURTHER AWAY (1 MI) AND NOT ON COLLISION COURSE. THE SECOND WAS CALLED AS 1/2 MI AWAY. I LOOKED FOR AND FOUND THE FIRST ACFT CALLED, THEN LOOKED FOR AND FOUND THE SECOND (CLOSER) ACFT. I INITIATED A CLB TO EVADE THE SECOND ACFT. WITHOUT EVASIVE ACTION, A COLLISION MIGHT HAVE OCCURRED. BOTH OF THE OTHER ACFT WERE FLOAT PLANES, EBOUND. SUGGESTIONS: CTLRS MAY BE OVERWORKED. THIS TFC SHOULD HAVE BEEN CALLED (FROM BRIGHT RADAR) SOONER, THE ACFT ON A COLLISION COURSE SHOULD HAVE BEEN CALLED FIRST, STEPS SHOULD BE TAKEN TO EDUCATE LCL FLOAT PLANE OPERATORS TO STAY FURTHER AWAY FROM BOEING FIELD ARR PATH, AND I WISH THERE WAS A WAY TO FIND AND VIOLATE PLTS WHO ENTER CLASS B, C, D AIRSPACE WITHOUT CLRNC.
