Sizes: see table below
- Deadrise is the angle between the bottom and horizontal on each side of the keel. Deep-V hulls run about 21-25 deg at the transom, which slices through chop for a smoother, drier ride (BoatTest).
- The cost is efficiency and stability: deep-Vs are harder to push, need more power, are more trim-sensitive and can roll at rest (BoatTest).
- In RC, deep-V monos are preferred for heat racing in rough water; one builder's notes put deep-V at about 21-26 deg and recommend 19-23 deg for heat racing (SV Design).
- Used on: Pro Boat Stealthwake (RC, 20 deg transom).
- The file is a reference example built by Xem Studio from the numbers above (Reference RC mono: 585 mm length and 20 deg transom deadrise (SV Design Stealthwake data); 181 mm is an unlabelled width in the same source's deadrise diagram.). Sizes the sources do not fix are illustrative; scale the example to your own vehicle.

Variable deadrise  up to 60 deg forefoot, 30-45 deg amidships  BoatTest
RC deep-V range  about 21-26 deg  SV Design (Stealthwake)
RC heat-racing sweet spot  19-23 deg  SV Design (Stealthwake)
RC mono CG  25-35% of length from transom, ~30% target  SV Design (Stealthwake)
