Structurally, that rig actually has quite a bit going for it. Aerodynamically, a few compromises have been made for sail handling but likely not...
Yes there is a major disadvantage of manoeuvrability at slow speed. As there are no rudders, steering is via vectored thrust and is typically...
Agreed on all counts. You're also going to discover that a 55-60m single mast isn't feasible either. The amount of structure required to keep it...
Arrived St Maarten this morning with support vessel, Abeona. Anchored briefly awaiting heli transfer from SXM, presumably then transfer to Koru....
@Fishsail does it have to be aluminium? There are several options in GRP e.g. Boston whaler, Carolina skiff, etc that are robust, decently stable...
Ocean Craft 3300 or 3800 +/- 12' very stable, nothing deflatable Might help if you're down under... http://oceancraft.com.au/
In case anyone might be interested, here is some info re: pumps and motors used in these ET systems. Pumps are Speck NP10 series triplex plunger...
Looks like ET disagrees with you. Notice how current draw and power required increases with increasing output? ;)
Yes, of course that's true. By definition, that means your system is oversized for a single membrane. There may be advantages in doing so.
In order of preference: 1. Utilise existing pump/motor assembly This is why I requested basic motor specs, e.g. voltage and frequency. Obviously...
Thanks Pascal, great resource. They're selling a plated HP pump that'll do 40gph for US$500 :D Have a feeling I'll be going back to their site...
It's definitely not a Cat but I certainly agree with you, the Cat 277 seems to be the gold standard for this size range. As you said, spares are...
This is the system, except with 2 pv/membranes. The system voltage (for some reason) is 230 Vac 50 Hz, hence the supply issues. My understanding...
I'm currently in the middle of a pretty significant refit and just pulled the old watermaker out of the lazarette. It's an EchoTec unit (hence the...
True. Hopefully I made that clear. At least he knows where to look now ;)
There's usually a reason for that ;)
Yes. No. Not likely. My guess is engine batteries are on one input, genset battery on the other, so output is from whichever is showing a...
Sorry! :confused:
APS = Automatic Power Selector Sounds like you have multiple battery banks (probably 2?) which are connected as inputs to this unit. There should...
Sounds like a solid set up. My own yacht has a small belt-driven pump off the single engine in addition to the main electric-driven pump, probably...
