</>What does Size Equals Speed do?
In real life, bigger boats are harder to move. In Raft with this mod, bigger boats go faster. We've decided that makes more sense. Size Equals Speed rewards your building efforts with increased drift speed. Every foundation you add makes your raft a little bit faster. Start with a tiny 2x2 and you're crawling. Build a massive floating city and you're cruising through the ocean like a speedboat made of wood and plastic. You control the math - set your base speed, how much each foundation adds, and when the speed boost kicks in. Want your 100-foundation megastructure to absolutely fly? Crank up the multiplier. Want a subtle boost? Keep it low. Your raft building addiction now has even more benefits.
</>What is Size Equals Speed?
In real life, a bigger boat is harder to move. Raft's vanilla drift speed agrees, which makes massive endgame rafts feel sluggish. Size Equals Speed reverses the rule: every foundation you add above the minimum threshold makes your raft a little faster. Start at a 4x4 starter and crawl. Build out to a 100-foundation floating city and you're cruising the ocean like a speedboat made of wood and plastic. You control the math — Base Speed for your starting drift, Speed Per Foundation for the scaling, Minimum Foundations for when the boost activates. Built in-house by ProjectMods, the community-first game modding platform and desktop app.
</>Common questions about Size Equals Speed
What does Size Equals Speed do in Raft?
It makes your raft drift faster as you add foundations. Each foundation above the Minimum Foundations threshold adds a speed boost based on your Speed Per Foundation slider, so the bigger your raft gets, the faster it cruises through the ocean. Built specifically because Raft's vanilla drift speed is the same regardless of raft size, which makes massive endgame builds feel sluggish. Now your raft-building addiction has a tangible reward — invest in a sprawling design and your floating city actually moves like a city should. Tune via the ProjectMods options panel; no game restart needed when you adjust values.
How fast can I make my raft go in Raft?
Very. Size Equals Speed's slider ranges go up to Base Speed 10 and Speed Per Foundation 10 — meaning a 100-foundation raft with cranked sliders becomes essentially a speedboat. At those values you'll outrun the wind, the current, and probably some sharks. Realistic ranges for a fun-but-not-broken experience are Base Speed 1-2 with Speed Per Foundation 0.1-0.3, which keeps drift feeling natural while rewarding bigger builds. For comedy chaos, max everything and watch your raft turn into a hydrofoil.
Can I set a minimum raft size before the speed boost kicks in?
Yes. The Minimum Foundations slider in Size Equals Speed defaults to 4 (so a basic starter raft drifts at vanilla speed) and ranges 1-50. Useful for keeping early-game pacing intact — you wouldn't want a brand-new survivor with 2 foundations zooming around because that breaks the survival ramp. Set it higher (say 20) if you want medium rafts to still feel slow, or set it to 1 if you want every foundation to count from the very first. The mod re-checks foundation count regularly, so the boost adjusts as your raft grows.
Will Size Equals Speed break the steering or physics?
At reasonable speeds, no — your steering wheel still works, sharks still chase, currents still apply. The mod just multiplies the underlying drift velocity. At extreme settings (Base Speed 10, Speed Per Foundation 10, 200+ foundations), you can outrun some game systems and the raft physics start behaving weird (hard turns, slight clipping). Stay within the chill 1-3x range for normal play. If things get glitchy, dial the sliders down — the change applies live, no restart needed. Pair with Story Skipper from ProjectMods if you want fast travel between every story location too.
Why would I want my raft to go faster in Raft?
Two main reasons. Story progression — endgame Raft asks you to travel between distant story islands (Tangaroa, Varuna, Temperance), and a sluggish massive raft makes those trips drag. Size Equals Speed turns the trip into a quick cruise. Content creation — slow drift footage gets boring fast on YouTube and TikTok; a faster raft makes for tighter edits and more dynamic shots. The Size Equals Speed mod from ProjectMods lets you keep the satisfaction of building big without the punishment of slow travel.
What options does Size Equals Speed include?
Base Speed
Your raft's starting speed. 1 = normal, 2 = twice as fast!
Speed Boost
Turn the bigger-raft-faster boost on or off. Off = normal vanilla raft speed.
Speed Per Foundation
How much faster your raft goes for each foundation added. 0.1 is a gentle boost; crank it for chaos.
Minimum Foundations
Speed boost only kicks in after you have this many foundations.
Size Equals Speed is a Raft mod from ProjectMods that makes your raft drift faster as you add foundations. Set Base Speed (your starting drift, range 0.1-10), Speed Per Foundation (how much each foundation adds, range 0.1-10), and Minimum Foundations (when the boost kicks in, default 4). Tiny rafts crawl, sprawling builds cruise like a speedboat — the math is yours to tune.
System Requirements
What features does Size Equals Speed include?
- Bigger raft = faster drift. Every foundation above the threshold makes you quicker.
- Three sliders — base speed, per-foundation boost, minimum threshold. Tune the math.
- Reward your build addiction with actual cruising speed instead of vanilla sluggish drift.
Best For
- Endgame rafts that need to make long story trips between distant islands without crawling.
- Content creators who want dynamic ocean travel footage instead of slow boring drift.
- Builders who think the bigger their raft gets, the faster it should logically be moving.
