Harbour Remote

Build a fleet around its batteries

Harbour Remote compares model boats through hull length and electrical fit. A 42 cm Harbour Sprint and a 74 cm Twin Harbour Cat make different demands on storage, handling and battery selection. The catalogue keeps cell count, connector and planning current beside each hull so these differences remain visible beyond the photograph.

The launch-battery worksheet compares your entered pack with every selected boat. Connector shape alone is insufficient: Channel Runner and Wake Line both list XT60, yet their specified cell counts differ. A dedicated Sprint pack and a Channel Runner propeller also have named model relationships.

Capacity and current produce an illustrative runtime using an 80% planning factor. Charged-pack count can then be considered across the fleet. Those figures organise an outing rather than predict its duration; speed, trim and water conditions affect actual running. The aim is a selection whose components and assumptions you can inspect before heading to the water.
