SeaStorm Boats

More than a boat. A partner for every adventure.

SeaStorm boats are made from high-density polyethylene (HDPE) by rotational moulding – every hull is formed in a single piece. The result is an exceptionally tough, quiet and stable boat that shrugs off knocks, rocks, salt water and strong sun.

From the junior SeaStorm 12 through the sporty 13 s and the versatile 14 to the spacious SeaStorm 17, the range is at home on lakes, rivers and the Adriatic coast – for fishing, family trips, water sports or as a yacht tender.

SeaStorm – built to last, made to enjoy.

Unique production method

One piece. Built to last.

Each SeaStorm is rotationally moulded from UV-stabilised polyethylene in a single piece. Without seams or rivets the hull is extremely resistant to impacts, large temperature swings and strong sunlight – and gives many years of reliable, low-maintenance service. SeaStorm boats are sold in more than 60 countries worldwide.

  • Rotationally moulded HDPE with UV stabilisers
  • One-piece double hull – no seams, no rivets
  • Resistant to impacts, heat, frost and UV
  • 100% recyclable material

Engineered for efficiency and comfort
01

Flat, efficient hull

Planes quickly and reaches cruising speed with a smaller engine – lower fuel consumption and running costs.

02

Self-draining deck

Water leaves the deck automatically, keeping the boat dry and safe without manual bailing.

03

Strong double hull

Full contact between deck and hull makes the boat stiff, robust and extremely safe.

04

Unsinkable buoyancy

HDPE is lighter than water – the boat stays afloat even with every compartment flooded.

05

No corrosion, low maintenance

Salt, oxygen and water do not affect HDPE. No gelcoat, no rust – just rinse with fresh water.

06

Quiet, smooth ride

HDPE naturally dampens noise and vibration, so the boat glides quietly across the water.

07

Easy shore access

Shallow draught and a tough hull let you land on beaches and reach shallow, hard-to-access spots.

08

Seven colours

White, light grey, dark grey, green, lime green, red or yellow – the colour runs through the material, so scratches hardly show.

Design

Designed by Mannerfelt Design Team
