Toys for boys. Old boys use computers, small boys need other toys We have nice ship https://www.thingiverse.com/thing:4912458 and how do You want to embark the ship? Or get pilot to enter a port? We need a pilot ladder. Well here are basic things - step and spreader preventing ladder from twisting. According to IMO resolution A.1045(27) steps should have efficient anti-slip surface must be equally spaced 31-35cm and remain horizontal 4 lowest steps may be made from rubber (usually reinforced by steel flat bars) 5th step must be spreader interval between spreaders should not exceed 9 steps permanent marking should be provided at regular intervals e.g.1m - in our case print steps in different colour Well, we can embark pilot. What about leaving the ship in emergency? We need embarkation ladder, which is located on port and starboard side beside life saving equipment - liferafts https://www.thingiverse.com/thing:4906523 and rescue boat https://www.thingiverse.com/thing:4906088 Embarkation ladder consist of steps, without spreaders, at the same distance as pilot ladder. And do not require marking. For everyday use (e.g.draught survey) we use lightweight monkey ladder. One thing is important - anti-slip surface. I'm old and lazy, so I use WiFi camera + cell phone to make survey. Safe and I have draught readings recorded. Making ladders is part of seamanship. Try it and make Your own. Have a fun. To make it easier I attached kind of mechanical clamp - slide it into step, tie knot on Your rope and slide inside the step Enjoy! it is made in not published version 5 of Template Shapes_Text https://www.thingiverse.com/thing:4863092 (CSV code compression). Code of ladder with compression to CSV consist of 21 lines. With standard OpenScad commands probably 3x more. template code will be included in next database release
