2Sail Sailing Simulator vs PocketFlow

Sailing simulator you really sail, multiple controls to master. Powerful coaching SIM game for sailors and non-sailors. 50 years of coaching squished into key lessons to learn & go faster Play as a guest, no login required. Optional donation to support ongoing development of app, keeping it free for all and with no adverts. The entire app, all controls and all levels are available at no cost, with no purchase or extra purchase. Now with multiple boats and sails Time Trials to test & build your skills Modules include: Learn to Sail, points of sail, leaving and returning to shore, going faster by using your weight & twisting the sail with the vang and more to come. Option to use all controls at once or learn each one by one. Warning: this is a fast way to learn or give you high end techniques to win, but sailing is not an easy sport so effort is required. Master the skills only the winners seem to have. Compete against others (invite your friends) Developed after 40 years real experience coaching learners and National winners, this simulator helps you learn & practice: Trim, balance, sail shape, twist, reefing, centreboard, gusts, wind shifts, course & start line bias. Makes sailing easy to learn and shows the tricks on how to win. Every race different, courses include upwind, downwind and reaching, all the settings and techniques change with wind strength and point of sailing. Training levels constantly under development ... each designed to build your skills, easily, one at a time. Suitable for anyone wanting to improve their sailing, yachting and racing skills. This would have to be the easiest way to learn about how to make your boat go faster. As a coach, I was keen that the visual clues are the same in the simulator as in real boats. No fancy graphics to look at, but shows what you need to do to go faster. As a developer, I am keen to make it work for you, say hello with suggestions Boat speed, heeling and pointing angle are all effected by combination of controls and wind strength. If you sail on a dinghy or a yacht this will help you to go faster and safer now download the simulator and start improving your skills

Real water, live on your iPhone. Free to try for 7 days, then one purchase unlocks it for good. Draw a shape with your finger or build one in 3D, and watch water pour over, under and around it as it happens. PocketFlow runs a real free-surface water simulation on your phone's GPU. It isn't an animation: every frame is solved by our own solver, so the water splashes, jumps and settles because the physics says so. NEW IN 3.3 Feel and hear the water: haptics and sound follow the flow as it surges and hits the walls, then ease to a steady hum once it settles, each with a one-tap button. Spray and thin water look lifelike. Plot any 3D section and share it. Import a model at Actual size, and Add and fit tank grows the tank around it. Heights read as real-world elevations, in tanks from 1 cm to 10 km. BRING YOUR OWN MODEL (STL) Import a CAD or 3D-print model from Build, Files, Mail or AirDrop, at Actual size or at a scale you choose. Models move, turn, size, snap and duplicate like any shape, can poke through the walls and floor, and can have up to a million triangles. TWO WAYS TO PLAY • 2D Sketch: a side view of a tank. Draw solids right in the water with a pen, box or oval, and the flow reacts straight away. Press and hold a solid to duplicate it, cut it out or size it exactly, with undo, redo and snap guides. • 3D Build: add boxes, spheres and cylinders. Slide them with an axis lock, size any side, turn about any axis, or type exact numbers. SLICE 3D INTO 2D Cut any 3D scene along or across the flow and open the slice in 2D, at full size or as a scale model such as 1:15. START FROM A TEMPLATE Press ▶ to run any template. • 2D: Open channel, Dam break, Sluice gate, Weir • 3D: Channel + pier, Weir, Dam break, Labyrinth weir, Dam & stilling basin, and Mystery dam: an STL dam, spillway and stilling basin at 1:100 SET THE SIDES Make each side a wall or open to the air. Add an inlet by velocity or by flow rate, or hold a side at a water level, with or without inflow. Drag any side to size the tank, set up to eight blocks of starting water, or start empty. SEE WHAT'S GOING ON • Show plain water, or color it by velocity or pressure • Section view in 3D cuts the tank open to show the flow inside, and an Ortho view gives true elevations and plans • Plot along the cut: water surface, bed, velocity and bed pressure Drag to read values; share as a picture or data. Bridges and culverts are drawn as they are, even running full • Tap any solid to read its elevation • Section and level probes in 2D • Stretch the height or mirror the 2D view for long, flat channels • Probe pins with live velocity, depth and Froude readouts • Streamlines that follow the flow • A measure ruler that snaps to walls and edges • Live In and Out, with a Filling or Steady cue TILT TO SLOSH Tap Tilt and tip your phone. The water runs to the low side, like a real tank in your hands. THINK FULL SIZE Working with a scale model? Pick a scale such as 1:25 and every number shows at full size, scaled by Froude similarity. TRACE OVER A PHOTO In 2D, add a photo or drawing as a background, set it to true size from a known length, and draw your solids over it. SHARE IT Save or send a photo with the color scale on it, or a 10-second clip. EASY TO PICK UP A seven-step Quick start shows you where to press. Scenes save themselves, Continue picks up where you left off, and Fast, Balanced and Detailed presets trade speed for detail. GOOD TO KNOW • Runs fully on the device: no account, no ads, no tracking, works offline • One purchase after the 7-day trial, no subscription. Bought PocketFlow before? You're already unlocked. • Made for learning, exploring and quick what-ifs. It is real physics, but not a certified engineering design tool: check real designs with proper engineering analysis. Great for students and teachers, engineers who want a quick feel for a flow, and anyone who likes watching water.
