The recipe has been removed from the experimental branch for now. Just give yourself one with the dev console. The command is ITEM SEAGLIDE, or better yet, ITEM POWERGLIDE. That'll get you the Powerglide which lets you go faster.
Have you found the required ingredients for the recipe? Recipes usually show up when u find 1 of the ingredients
Again... it does show up when you find partial required ingredients.. lubricant... magnetite... maybe a bug, but it seems like those ones will make it show up, need to confirm with Dev if its those main-ingredients and it will show up or if it should show up after finding titanium(seaglide)/crafting computer chip(compass)
In general, for a lot of items, recipes are shown in the fabricator after you find partial ingredients to craft it... cause crash on planet, you have no idea if there magnetite or lubricants(creepvine, player doesn't know what all the alienstuff is that can craft it ), so once those are feasible ingredients, the recipe is shown... Encourages exploration
