can someone tell me how to spawn this boat in game??

@duration You can either spawn it via trainer or buy it from website. Example:
https://www.gta5-mods.com/scripts/pc-trainer-v

@JammersXAM Thanks!

actually you can have the canopy using enchanced native trainer without change the model.

@Clark Could you make more boats please? Ones that are add ons. There isn't alot of boat mods. Types could be: Passenger ferry, a medium fishing boat, a driveable military aircraft carrier. I'll leave it up to you what one you want to do though, they are just ideas.

@Raketaz Sorry, I wish I could but I'm not that kind of a modder, this tropic was just simple work. Although there are some guys working on those boats that you mentioned. They'll prolly release them by the end of this year.

@Clark Could you make this into an extra for the Tropic or just as an add-on so it doesn't replace the original model?

@Number1GojiFan Sorry, I'm really not sure how to do both versions you asked. Although you can control the boats extras while in it via enchanced native trainer or Menyoo PC trainer.

@Clark Alright thanks, man :). With your permission, could I ask someone else to turn this into an extra or even an add-on and then send it back to you for you to upload yourself or simply give you credit for the original model?

@Number1GojiFan Sure, do whatever you want with it! :)

@Clark Ok, thanks man :D.
