It came with The <a href="http://www.outdoorgearlab.com/Portable-Solar-Reviews/Goal-Zero-Nomad-7" target="_blank">Nomad 7</a> panel and the Guide 10 battery pack/ charger. The quality is great and the panel charges my cell phone in abt 2 hrs. The Guide 10 battery pack takes abt 4hrs to charge from the panel and holds 4 AA batteries. The charged battery pack will charge my phone almost 3 times before needing to be recharged. I imagine the same would be true for a handheld gps or vhf. A big plus for me is my navigation lights and fans on board are powered by AA batteries so I can use this to recharge them over and over while sailing. I've already sourced some of the best rechargeable AA's on the market and they aren't too bad. While this setup will be ideal for my Tiki 21 I imagine it would be a bit lightweight for a T26 or T30. So I only add this for any small Tiki owners who may be reading and to say that the quality from this company seems to be top notch and the products meet or exceed the advertising. (Which can be rare) Also the larger kits they offer while they my be expensive keep in mind that in most cases the battery is a lithium ion and will out last and out perform any AGM or lead acid equivalent.

<p>And that bastard Murphy! Thanks mate for your valuable input to this discussion. I am sure it will be helpful to others as well. In a lot of ways i think we are on the brink of new tech for power supply, almost like the beginning of the steam age when it's true potential to humankind had not been fully understood or realized.</p>
<p>On the weather front of here just to be smug, it was 32 degrees c with humidity.</p>

<p>DISCLAIMER - This is based on research not experience.</p>
<p>From your list [very like mine] Nav Lt all night = 1ah. Cabin Lt less but say another 1 ah. Fishfinder i dont know but laptop 1 hour = 4ah. VHF receive very little, broadcast {25watt] 30 min = 1ah. Spotlight [car halogen bulb] 50 watt but say Led alternative 5 watt 1 hour use 0.5 ah. Add up and round up =8 ah per day. Some elastic here already - how often will you run your Nav Lts all night / etc...Still we must start somewhere so 8 ah / day is the drawdown.</p>
<p>BEST CASE for panels is about 0.4 ah per watt of panel per day. So best case for 40 watt panel approx 16 ah /day. Engineers often use half this output when designing systems so 8 ah reliable. 12 would not be unreasonable as a summer average perhaps. So you are spot-on with your 2 x 20 watt panels.</p>
<p>The recommendation for storage is usually output x 3. So say a battery of 30 ah. This will give 10 ah of power without stress.</p>
<p>So worth looking now at what we have with 40 watt panel and 30ah battery. First off there is enough in reserve to run for a day without any charge. For occasional heavy use we can draw maybe 20 ah in a day. This will use up both the incoming panel charge and the battery reserve. This is 250% the designed daily load. Of course you must use very little next day if you want to top the battery back up.</p>
<p>So weekenders should spend on batteries to store all that elec. generated on weekdays but liveaboards should invest in panels for constant supply.</p>
<p>There is a seperate case to be made for a minimum of 80/100 ah battery as this will allow you to run domestic power-tools of 500 watts or so for an hour with an inverter - very handy at fitting out or small repairs.</p>

<p>You might consider using a tiny tiller pilot to operate a trim tab you could "Wharram stitch" on to the aft edge of the tillers with a tiny crossbar to operate them together. You could re-fashion the designed rudders to make their trailing edge straight in stead of with that angle and that way the trim tab would work ok. Those tiny tiller pilots use very little electricity. We have one on Peace IV that operates an air paddle for our Monitor Wind Vane because Peace accelerates and decelerates so much the Monitor gets confused. The tiller pilot keeps a compass course which is better for us. The Monitor would be too heavy for a little boat, but there used to be a light weight Navik vane that would be maybe ok for the 26 or the 30. Rory had a self steering system on his 21 that went around the world and twice across the Atlantic but I don't remember what it was. Rory, are you still around here? Comments please! </p>

<p>You are right there about the autohelm mate, my thinking is first to get the boat in the water with the basic electric set up. Play with the windvane first so that it is set and working. At a later stage i will add another battery dedicated to just the autohelm, with it's own panels etc or add the battery to the house bank, not sure yet.</p>
