If you're doing your own design to accommodate main engine failure, it might be smart to consider the impact of stabilizer failure. If we would have continued with our circumnavigation plans I would have added paravanes to Alanui. Since we opted for a near coastal route I didn't install them. Remember when Uno Mas lost here stabilizers on the NAR: http://www.nordhavn.com/rally/gallery/leg2/unomasstabilizer.html Powering your hydraulic systems with the Wing/Gen/Watermaker/Stabalizer/Battery Charger power unit might make a lot of sense. Wait, now with all that do I need a backup for these systems? Oh God, a backup for the backup! What have we done! Scott Bulger, Alanui, N40II, Seattle WA
