This is the easiest of the boss fights but that doesnt mean that players shouldnt keep their guard up.
Fastest boat stranded deep. Each vessel is significantly faster than its previous version with. While it may not be as fast as a Boat Motor a sail does not need to be refueled and one can still easily outrun sharks with it. So in short you have 2 speeds.
Allison makes a slightly smaller boat the SS-2001 SuperSport but the GrandSport offers a little more room and usability. Stranded Deep is one of the most darned games you can throw on your face right now. It helps you get up to speed but doesnt increase the max speed.
Sailis a craftable item which can be placed on a Raftto be used as a type of Propulsion. Engine ofc is much faster but it doesnt stack with sails. You must first construct a raft base with the various kinds of buoyant scrap you can find.
The sea anchor wont deploy in shallow water. Probably the fastest production boats. The sail is much easier to craft and is also quieter.
This was my understanding of the experiment someone did. The base can be crafted from Barrels Buoy Balls or Tires found aboard Derelict Vessels and also Sticks. The Raft the Karve and the Longship.
While the Raft is less stable then the Life Boat it is approximately 15x faster 2x with a Boat Motor. Rafts are created from three components - a base a floor and propulsion. To make a Crude Axe all you need is a Stick a Rock and some Lashing Rope.
