Rough Weather Training: Alexia Takes on Heavy Seas

November 11 2026November 11 2026 Karel Overlaet, RIB Advocate

Rough Weather Training: Alexia Faces the Atlantic

Rough weather training takes Alexia to the Raz de Sein and Chaussée de Sein, France, where strong winds, powerful waves and changing conditions challenge her skills.

Since 2017, she has worked in yacht charter operations aboard catamarans in Panama, the Bahamas, the Mediterranean and Polynesia.

Today, she is in her second season guiding responsible orca encounters aboard rigid inflatable boats (RIBs) in northern Norway.

Following module 1, “Fundamentals of Adaptability,” Alexia advances to module 2 of the Operational Learning and Management (OLM) programme, “Adapting to a Dynamic Environment.”

This video follows her progress as she learns to read waves, anticipate changing sea conditions and make better navigation decisions.

The programme combines practical seamanship with stress management, situational awareness and decision-making. On-water exercises and debriefings help sailors develop confidence, improve boat handling and navigate challenging offshore conditions safely.

The Editor’s View

I highly value Olivier’s approach to rough weather sailing training. That’s why RIBsONLY.com features an extensive collection of his training videos, showing how to improve navigation skills, boat handling and confidence in challenging sea conditions.

But what exactly defines a rough sea, and how do we classify its conditions? Find out in my article: Wind, Waves, Swell: Beaufort vs Douglas Sea Scale.

SeaQuest 660 RIB Test: 44 Knots With Mercury 225 V6

November 10 2026November 11 2026 Karel Overlaet, RIB Advocate

SeaQuest 660 RIB Sea Trial: Real Speed and Fuel Consumption

The SeaQuest 660 RIB returned to the spotlight as a compact 6.60-metre boat with a racing heritage.

Its hull originally competed for nearly 15 years under Kostas Karantonis, collecting numerous victories.

The larger SeaQuest 760 later evolved from this design.

Both models shared the same hull characteristics, beam and seating arrangements, while the 660 offered a shorter bow section.

The layout included generous storage, a two-person helm seat and a three-person aft bench convertible into a sun deck.

Standard equipment included GPS, an electric windlass and foam decking.

Cruising speeds of 30–33 knots were recorded with two people aboard.

Fuel consumption remained particularly interesting below 30 knots, where measurements indicated just 0.8–0.9 litres per nautical mile.

SeaQuest 660 RIB: Sea Trial Results

Test conditions: Mercury 225 V6, two people aboard, approximately 150 litres of fuel.

Engine speed	Speed	Fuel consumption
3,500 rpm	23.5–24 kn	0.9–1.0 l/NM
4,000 rpm	27.6 kn	0.9 l/NM
4,200 rpm	30–33 kn*	1.0 l/NM
4,500 rpm	31.7–32 kn	Not reported
Maximum	Approx. 44 kn	Not reported

source, data may vary

*The tester associates 30–33 knots with approximately 4,200 rpm. These figures should be treated as reported observations rather than a fully verified performance curve. Fuel consumption is expressed in litres per nautical mile, not litres per hour.

The Editor’s View

Out friends at the greek Boat & Fishing Magazine are very thorough in their sea trials generating real life data.

Many buyers who are digging deeper often ask that question.

It’s not easy for the dealership to answer that question so here on RIBsONLY.com you will find plenty of answers on that matter.

Zulu 37C: High-Speed Powerboating on the Baltic Sea

November 09 2026November 11 2026 Karel Overlaet, RIB Advocate

Zulu 37C: Stunning Footage of a Swedish Power RIB

The Zulu 37C is a Swedish high-performance powerboat designed for speed, precision and offshore handling.

Built by Zulu Marine, this 12.05-metre boat combines a lightweight hull with powerful Mercury Racing outboards.

Its semi wave piercing hull form designed for low impact makes for an exceptional comfortable ride in rough conditions.

Its narrow 2.70-metre beam and low-profile design make it stand out from conventional offshore powerboats.

The hull uses vacuum-infused carbon fibre or glass fibre construction to reduce weight while maintaining strength.

If you’re interested, youcan choose twin or triple Mercury Racing 400R or 500R engines.

Depending on the configuration, Zulu Marine reports top speeds ranging from 73 to an impressive 95 knots.

The Zulu 37C on the Baltic Sea offers an interesting look at a Scandinavian approach to high-speed boating.

Rather than focusing on spacious accommodation or family cruising, this Swedish powerboat puts performance, responsive handling and speed at the centre of its design.

The Editor’s View

The Swedish-built Zulu 37C, designed by the renowned naval architect Petter Martens (LinkedIn profile), takes to the seas with a clear purpose: speed and precise handling.

This Scandinavian powerboat isn’t designed around generous living spaces or relaxed family trips. Instead, it prioritises performance, sharp responses and the driving experience. I hope one day to get my hands on it.

This amazing video was published on the Zulu Marine YouTube channel.

A Detailed Walkthrough of the Maxline 38 Family RIB

The Maxline 38 RIB by Tiger Marine combines a flexible deck layout with comfortable accommodation for short family cruises.

Measuring 11.95 metres long and 3.75 metres wide, this 38-foot rigid inflatable boat offers twin outboard engines ranging from 300 to 400 hp each.

The walkthrough by the Sea Team reveals a spacious aft cockpit with an electrically adjustable table that converts into a sunbed or disappears into the deck.

There is also a large stern garage, generous storage and a configurable outdoor galley.

Forward, the T-top protects the helm, while wide walkways provide easy access to the cushioned bow lounge.

Below deck, the Maxline 38 features a forward double berth, an additional aft sleeping area and a separate bathroom with shower.

Designed for couples and families, this RIB combines practical cruising features with adaptable outdoor living spaces, according to the reviewer.

The Editor’s View

This walkthrough was filmed by The Sea Team, a team known for its thorough and detailed RIB reviews.

Their sea trials are equally comprehensive, offering valuable insights into each boat’s performance, handling and features.

That’s exactly why I enjoy sharing their videos here on RIBsONLY.com.

Seadelta SD 600 RIB Test: 45 Knots With Honda 150 hp

November 04 2026November 08 2026 Karel Overlaet, RIB Advocate

Discover the Seadelta SD 600 Combining 45-Knot Speed With Comfort

The Seadelta SD 600 was among the Greek boatbuilder’s first RIBs and has become one of its bestsellers, according to the owner.

Designed to offer the comfort and handling of a larger boat, this 6-metre RIB combines performance with practicality.

Its specially developed variable-deadrise hull delivers a smooth, controlled ride, even in challenging sea conditions.

Engine options range from 130 to 200 hp, although the manufacturer considers 150 to 175 hp an excellent balance between performance and fuel efficiency.

Powered by a Honda 150 hp VTEC outboard (see specs below), the Seadelta SD 600 reportedly reaches 45 knots, with average fuel consumption of approximately 1 to 1.1 litres per nautical mile.

The spacious layout includes a protective console, generous storage, comfortable seating and a practical bow arrangement.

Attention to construction quality and detail makes this Greek RIB suitable for family cruising and professional use.

The Editor’s View

The Greek authorities officially list www.seadelta.gr as Seadelta’s website in their boatbuilders’ register, with the entry dating back to 2022. However, the website is not active, so I have been unable to verify and publish the official specifications at this time.
