On A New Tack

How to revive a failing water pump (and make it better!) This is a companion blog article to a YouTube video we did on the same topic. Disclaimer: You must be electrically and mechanically competent to complete these repairs/upgrades.  If you are unsure of any step, stop and get professional assistance.  You can always reach out to me and I will try my best to help. Our Vision 444 ES catamaran uses two freshwater pumps, one in each hull.  Each one is a 24V diaphragm pump made by Pentair.  Don't worry, the same steps apply to 12V pumps. We have one in each hull, but we also have crossover valves, which when we open, allows one pump to pressurize the water on both sides.  We normally operate them this way so that we drain water from one tank, then we can switch which pump is powered up and pull from the other tank. About a year after we launched, the port side pump started acting up.  It would sputter and get sporadic in running as it got close to the cut-off...

The Davit System The Vision 444 comes with a Carbon Fiber Davit system that is used to hoist a dinghy.  As time has gone on, some of the exact specifics of the davit system have evolved and changed slightly, but for our boat (Hull #11) and the ones near to it, this is how it operates.  Two Main Steps First, after attaching the dinghy to a forward and aft attachment line, the davit arms are raised; pivoting on axles which mount the davit to the transom of the boat.  This step is accomplished by attaching a line which runs through several blocks to the starboard, aft power winch.  Pressing "2" (low speed) on the winch power buttons and raising the davit into its full upright position, where it can be lashed to the boat with Dyneema loops. Second, is to raise the dinghy to be close under the horizontal beams of the davit arms.  The dinghy attachment lines, that are attached to the dinghy's bridle, run up through a fixed block at the end of the davit arms and then t...

A Clean Anchor Chain? Okay, so why would you want a clean anchor chain?  Two reasons, really.  First, if it's muddy, we really don't want all that muck getting in the anchor locker, and second, it's no so much clean, the goal is really to have no salt residue left on the chain. Chain is zinc galvanized, so it is corrosion resistant, but there is only so much zinc on the steel chain, so the less work that zinc galvanization has to do to protect the underlying steel, the longer it will last! Manual Cleaning Up until now, we have been able to use a fresh-water hose and multi-position sprayer set to mist, which I would lock into "On" and then position the sprayer so that it would spray down through our bridle access opening to rinse the chain on the way up. When you are in sandy anchoring spots, that is pretty much all you need; just enough to get the saltwater off. Now, there have been times where we anchored in thick mud (the Chesapeake Bay, Maryland, USA and Cocori...

We made it to Grenada! Quick note: Jump to the bottom if you want to help us cruisers help those impacted by Beryl in the West Indies After an overnight sail from Martinique, we finally got all situated on a mooring ball in True Blue Bay and then I dinghied over to get us cleared-in.  I went back to the boat.  A tropical wave was very far east of Grenada, but those always turn north of Grenada or fizzle out this early in the year...  This was on the morning of Friday, June 28. This Tropical Disturbance is not doing what its supposed to New updates and projected tracks are available every 6 hours, so every 6 hours we would take another look and make sure we were in the clear.  As we went to bed Friday night, after our 25 hour sail, we weren't feeling in the clear. By the next morning, things were not looking better.  Actually, they were looking worse. Most of the tracks had the eye of the storm going north of Grenada, but there was always a straggler or two that ...

Giving you more fuel tank options  One of the great things about catamarans is the redundancy in just about every system.  Fuel tanks are no exception and having a tank for each engine is nice, but it can be made nicer with a transfer pump or better yet, the ability to pick the tank that each engine pulls its diesel from. But why? There are couple of reasons that you may want to do this.  Maybe one engine is not working and you want to be able to go further by using fuel from both tanks for the engine that is working. If you are getting fuel from an area where this is concern about the quality, you can fill one tank with the suspect fuel, and if it in fact turns out to be bad, you still have the other tank that is known good to fall back on. We normally run both engines from one tank just so that it is a little bit easier to fill when the time comes.  This is a minor issue on our Vision 444, since the two fuel tanks are just in front of the base of the mast. The fill...
