Hi Mike,
Does the area under the cockpit seats drain completely?  If there is any standing water, you will certainly develop algae.

Do you have anything heavy up in the bow - big batteries, always full water tank, holding tank, anchors, extra gas tank … ?  Think of the boat like a tetter totter.  If you move heavy gear from the bow to the stern, you will change the fore/aft trim and allow the cockpit to drain properly.

The boat is fastest with a slightly bow down trim.  Bow down trim maximizes the water line length and minimizes the drag from the aft section of the hull.  Also, the unloaded hull trims slightly bow down to allow for the additional weight of crew in the cockpit when sailing.  Is there anything heavy you could store in the lazarette compartment and then move to the V-berth when sailing?  Keeping the water tank and holding tank empty when not sailing will help.

No doubt due to standing water, usually after a rain.  Cockpit drains appear to be working well.  I have an Torqeedo OB, which is lighter than an 6hp or more OB.  Other than putting some extra weight on the aft end to tilt the boat slightly more to allow drainage, any ideas?  I was thinking maybe bleach or vinegar spray after a rain. Don’t have any pix. Thanks in advance
