We decided to go black on the bottom paint color this time. This will give us a good indication of how the new paint is wearing- If we see the original red starting to coming through, we'll know that the latest bottom paint has ablated away and it's time to re-coat. With all the interior work we've done on the boat (and gear we've brought on board) the boat was trimmed down a bit in the stern. To keep the topsides clean from growth when fully loaded with fuel and cruising supplies, I raised the bottom paint from mid-ships back to the transom about 4"- something I've been wanting to do since we launched the boat.
Another item that I knocked off my to do list was a re-pitch and balance of the prop. We were generally cruising at 7.5 knots (our "economy cruising speed") at around 1800 rpm or so. I had 2" added to the pitch of the propeller, making it a 34x26 prop. Now we get our target cruising speed at a slightly more leisurely rpm of about 1600 or so. This feels just about right now, and the exhaust temp shows us that we are still loading the engine correctly to keep the machinery happy.
Keel cooler with new zincs anodes.
Hull anode- still in good shape.
