The site doesn't like extremely long word soups so my message was cut and actually forgot what I wrote next so I'd ad-lib the next again lol.

Gaff sails are better as they are wide and not too tall compared to Bermuda rigs. If you have extra mast height, you can add Gaff topsails above the Gaff (the stick) and the Gaff sail. It's visible in my Sailboat Teaser.

I apologize if this felt quick as the last few messages that were cut were actually two more paragraphs long but that's basically the very summarized version of it. I apologize for the late reply too as I was sick these past few days.

@Monarchii
Please pin this so you don't lose it. I will explain it with these in mind: zero engines and zero fuel included in the build— pure sailing. Additionally with realism in mind, so waving sails will be the primary means of doing it.

Working sails in SimplePlanes use primarily one method: wings. This of course is obvious but I'll tell you how they function. It is extremely difficult to make a square sail (four-cornered, the ones who catch running wind) as SP wings doesnt seem to like to bend in a realistic fashion and additionally, they dont seem to really be efficient in giving your boat enough push, with how much wind you give it. For example, even if you resize the wing in Overload to trick the game into thinking it's a larger wing, you will need a couple of them to make it wave thus weight becoming an issue. Reduce weight = wings sputter everywhere even with a slight wind breeze. Don't resize them and let too much wind just push you? Unrealistic and honestly could screw with other sails. This is the main reason as to why I never made them.

Unless you want to compromise with a static square sail, the bestest option is to ditch it all together and use jibs and either a Bermuda mainsail or a Gaff mainsail. I obviously will pick the Jib+Gaff sail configuration as this aligns with how SP wings work and is the easiest way you can make a sail rig actually function realistically. See Choufleur, outdated but this works as the very basic sail config I used.

Again, although I didn't say it was impossible to make square sails (I have seen at least two people try two different methods of their own and both worked), square sails are extremely expensive to make it look realistic (sail HAS to bulge to the middle as it is often tied to all four ends of the sail, not top and down only). Hinges are the primary culprit along with segmenting the wings themselves. The least I can tell you is to use triangle wing sections and piece them like puzzle pieces with hinges binding all together. Again, very expensive and not very efficient in doing their job at catching running wind, SP wings doesnt work best with that.

For now, I will tell you why Jibs and Gaff sails work best for SP. DO NOTE that always identify which is the leading edge of the wing and use it as the actual leading edge of the sail. Jibs are often triangular, this helps you in making the shape as well as making the sail flutter.

oh right, @Shironeko, care to tell me how a square sails works? I mean I know they can pivot but how far can they pivot cause I'm curious XD, also they aren't like lateens in the way that they catch wind right? as in they don't autocorrect themselves, sailships are more fascinating than i thought but it's tricky to make the hull low parted XD, though I will say I am figuring a little bit out of it, maybe next time I'll make it normally instead of face-up method i used for all the other 21 ships(yes, excluding the beetlecat) lmfao, I wanna make Hamernam(the sailship between HMS Courageous and SS Capercailzie (steam yacht)) actually work lmfao

P.S. download the 2,000p+ prop at your own risk, but all jokes aside, it runs on my 1gb device so no way it can't on yours right? :3

I guess low-part is really my niche-forte, lazy efficiency I guess.
