>>98436916I was going to mention this, simply because I didn't think that anybody else had watched Zak Storm.
>>98439342>>98439435An auger would probably not work as well as you might imagine, especially when you are floating around with little leverage. It could still function (you can push back on the water) but not as well as standing on solid land.
On the other hand, wrecking the rudder or taking the oars would be far easier and probably far more effective (assuming no sails) and you'd just need some pikes to steer the boat wherever you'd want from that point. Metal boats are going to be more of a problem, but at that point your merfolk will have better technology to deal with them, too.
