Brian, MS, HelloSailor
Thanks for the feed back - especially from CD/Brian - having it from a cruiser helps.
The Gemini's 80w, 3 optima's and 12C controller with an XBM was okay for that boat because of the propane refridge freezer - this boat and it's intended use are so much different I'm really feeling out of my league.
Brian, going cruising about October 2015, ICW to Fla, then island hopping around counter clockwise most likely - KW to Cancun style, then onward around the rim. Nothing set in stone, but heavily toed into the sand.
MS, I hear you on the heat. Idea scrapped firmly. Let's say I go with 6v's as described and 4 of them fit in the compartment I've already detailed. Is it safe to put the other 4 within 8 feet of 0/0 cable and make it one bank - without excessive voltage drop killing me?
Hello, that bank isn't 'in' the bilge - it's well above it, high and dry.
I may alter my davits to hold two panels - I'm looking at the specs and it says a 240w is 65 x 40 (average, roughly). That's a big chunk of sky.
Really weren't made for that much panel - and they are too low to duck under when using the ladder.
2015 - no telling where we will be! Hopefully see you out there though.
I would consider (maybe) removing the davits and have an arch built that hung off the back. You have a wonderful design for it. I would make it 2 " out of aluminum. It will be very light, relatively inexpensive, and large enough to run large diameter wire(s) - think gps, wifi, cell booster, solar panels, stern lighting, etc. That is what we have running through our solar arch right now. The light hitting the stern is a Godsend when anchored and coming in at night... esp given you dont have a sugar scoop. I am not a fan of SS for arches. Way too much weight and small diameter tubing. If you build a ss arch to accomdate that much wiring, it will sink the boat and cost a small fortune.
If you design the arch right, you will be able to double it as a davit. Aluminum being light, you may get away with getting it higher off the water line with less weight aloft. That was my one screw up... the arch will hold my tender but I already had davits and designed it with that in mind. Of course, you could do the same, but going back, I would make them one unit. I am not a big fan of when people make these massive davit towers that haul the dink 12+ feet out of the water, but you will want to keep engine and all out of the water and much of your coastal will be with her sitting there versus on deck. Keep the barnacle growth down and the speed up. Remember, the shaft of your tender hangs down a couple of feet under your tender... so when designing, keep that in mind (should you care to do that at all). ALso, you might be able to sell your current davits online to someone not cruising. ALl of this is just my opinion and obviously feel free to toss it away. It was just my first thought.
I LOVE that aft deck you have. Keep it clear. Nothing better than a couple of chairs there on a nice sunset.
I like the Irwins. Congrats on your boat. We ran across a great couple in the Tortugas that sailed a Irwin and had returned from a very long time in the Bahamas. She will make a good home for you.
ALl the best. Feel free to call or PM me with any questions if you want. PM me for phone number. Never a prob for you.
