Mixing AGM and wet cell batteries

I''m about to add a deep cycle wet battery as the starter. The existin deep cycle AGM batteries will become the house bank. The charger is set at 13.6 volts, which (I''m told) is ideal for AGM bateries. The charger will also be hooked up to the starter battery. However, since it will also get charged by the engine''s alternator (at 14.2 volts), it seems to me that it should get an adequately charge every time I run the engine to leave and enter the dock and marina. Usually, the engine is on for about 30 minutes to get to decent sailing areas. Also, once the engine is turned off, I will switch to the house bank for power. I don''t intend to use "Both" unless there''s an emergency.

Will this setup be ok?
