Your approach sounds fine and should almost work. From those options I'd choose the 24/24-12 which will supply up to 240W @20V. These converters...
Hard to say for certain but it looks like that bolt failed due to bending/shearing stresses. Bolts and threaded rods are intended for axial loads...
One option is the Royal Fleet Auxiliary, there are openings from apprenticeships to officers. Naval support vessels manned by civilians, it's an...
As there's a current dynarig thread discussing MF's installation, here are a few photos showing some rig details. She's presently lying in Simpson...
Having been involved intimately in the design and construction of one of the variants back in the day, I'd say his summary of the project is...
Nothing would please me more but I fear it would quickly degenerate into a hand-waving, yacht club bar type discussion where each party argues for...
This sounds delightful. I too am an aficionado of traditional vessels, albeit raised on the other side of the Channel. Dutch barges were a common...
Please note that catamarans of this type, i.e. non-racing, do not utilise running backstays. The mast is held up by a 3-stay system at approx 120°...
Were there any questions in particular?
Maybe a good candidate for this thread? ;) https://www.yachtforums.com/threads/disappointment-in-yacht-designs.38235/
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...

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...
