As for additional concepts, you may want to add maneuver engines like on big ships. Jet engines are the answer lol well, every engine does. Also high speed boats don't like time warp at all. Also buy a lot of chips and drinks, as it may take a whole day even with time warp. Add mining ability reaching shores to be able to go around the globe.
Also due to high water drag you will waste a lot more fuel compared to flying the same distance. As a result, you will have trouble keeping your boat straight at high speeds due to leverage growing with the distance from CoM on those designs and random bounces. Drag grows faster/stronger than buoyancy kicks in on the side that submerges more. It's easier to fly at those speeds than glide the water. Because at that speed flat boat body alone has enough lift. At some point lifting the body above water at pitch you turn into deadly flipping "plane". Real life racing boats have the same issue. Because your drag is so much less in air. Tiny jump on wave and you are flying on those wings intended for water! Even faster, just not in water anymore. Once hydrofoil reaches surface, it turns into air wings. Too much lift from air, too high drag in water above that. It's like some kind of sound barrier for boats you are stuck with. Slightly less actually because of the "wing" problem. Top speeds of realistic hydrofoil assisted hovering are close to 100m/s just like for the most powerful boats. Also at high speeds it is hard to keep it in water due to KSP SAS flying straight line and Kerbin being a sphere.Ĩ. But that is not really hydrofoil, you just glide on your air wings while "scratching" water. It's is rather easy to make plane fly above water with some tiny wing in water. and it's more like one moment you float and the next one you fly already. As your speed grows, so does your lifting force, you lift a bit more and your water drag is reduced further (considerably) and you can go even much faster. The problem here - it is very hard to keep those "floating". Air has less drag for the same lifting work so you can go faster and lift most of the vessel out of the water reducing drag a lot. best results can be achieved making water plane - transfering most of the lift required (~drag) to air wings instead of water. Optimizing one you will increase other, because you still have to submerge exactly same volume due to same mass.ħ. there are 2 kinds of drag - frontal and surface. Scott Manley once created electro-mechanical paddling boat. You can have engine above water like on hovercraft or below - it will still work. Boat tours look good only with drinks and half naked people of your choice. Which is very boring travel speed in KSP (and in real life in fact). My top speed is above 100m/s for a boat, but it's just about power and keeping it under control. It slightly optimizes the drag, but still it is bound to mass you have to lift, so not muchĤ. you can use hydrofoil to get out of water. Ponton will work the same as the main body (just add more mass for construction).ģ. Thin or fat pontons will work pretty much the same. Amount of that water basically defines your drag too.
Your mass requires the same amount of water pushed out.
