for Superyachts

Live radar. AI passage planning. Charter viability scoring. Daily digests. And a vessel playbook that gets smarter every time your captain acknowledges an alert.

5 New Features

Every weather decision, covered.

From live radar to AI-powered passage planning — HELM gives your crew the weather intelligence to make better decisions, faster.

Weather Alert Resolution Log

When a captain acknowledges a weather alert, HELM asks how they handled it. Over time this builds a vessel playbook. Claude surfaces matching past resolutions when similar alerts fire.

Quick options: 4
AI matches: Automatic
Builds: Vessel playbook

The Resolution Log

How the playbook gets smarter.

Every acknowledged alert is a data point. Over a season, your vessel builds a unique weather decision history that Claude uses to give smarter, vessel-specific recommendations.

01

Alert fires

HELM detects a weather threshold breach — wind, swell, visibility, or forecast change.

02

Captain acknowledges

One tap to acknowledge. HELM immediately asks: "How did you handle this?"

03

Resolution logged

Quick-tap options: postponed / rerouted / proceeded cautiously / no action. Optional note.

04

Claude learns

Next time a similar alert fires, Claude surfaces the matching playbook entry with full context.

“The passage window planner saved us from a nasty Mistral crossing. Claude flagged the afternoon thermal build we would have sailed straight into.”

Capt. James Harrington

M/Y Azure Horizon · 52m

“I get my morning digest at 07:00 every day. Vessel health, charter pipeline, financials. I haven't called the captain for a status update in three months.”

Alexander Rothschild

Owner · M/Y Azure Horizon

“The charter viability report is now part of every booking confirmation we send. Clients love seeing the weather risk score before they commit.”
