The day builds 'poco a poco' to a crashing overnight crescendo:
Stargazer bids a fond farewell to Old Harry. Poole's famous chalk stack, at the tip of Ballard Down.
Which separates Studland and Swanage bays. Stargazer's skipper opts to take his afternoon siesta anchored off the beach in the latter. The most seaward of the pair.
We leave at twenty hundred. So as to have a couple of hours of daylight, to settle into a passage making rhythm.
For, during the day, each successive forecast update adds a knot or two to the wind strength. We will be sailing in twenty five knots of breeze. A full force six on the Beaufort scale. It will also be well forward of the beam. Meaning that Stargazer's motion will further increase the Apparent Wind strength.

Stargazer's skipper is therefore keen to experiment with a part furled jib. It balances the helm, with a double reefed main set, and reduces heel. But turns out to mean, as suspected, that Stargazer cannot sail close enough to the wind for tonight's purpose. (See short leg, at the start of our passage, where we are heading for Cherbourg. Aided and abetted by the last of the east going tide). The turn of the tide fails to fully remedy the problem. However, unfurling the full jib, in combination with a west going tide, has the desired, dramatic, effect on both speed and angle. (See long diagonal leg, Poole to Casquets.) Albeit a night of hand steering is required. The combination of a lively seastate and spirited sailplan, overwhelming the autopilot.

The spring tide is at its height. Carrying Stargazer three to four nautical miles west per hour. The requirement is to race across, before it turns east. Then slip into Guernsey by the 'back door.' Around the Casquets. Where, because of the circular flow around the Channel Islands, the tide is slack becoming favourable. Whereas, ten miles away, on the other side of Alderney, the Race is cascading northward at seven knots or more.
(See Ad Lib 40 for chart marked up with positions of places mentioned)
It is a challenge which Stargazer rises to. Once around the Casquets, the seas smooth to a low regular swell, and the wind drops to a pleasant twelve knots. All that is needed for Stargazer to reach a respectable five knots. The autopilot takes back the con. Allowing Stargazer's skipper the luxury of a fried eggs and mushrooms breakfast in the cockpit. Watching the scenery slip by.
On the horizon, a puff of white cumulus cloud marks the spot where Guernsey lies unseen. By the time that coffee is poured, three grey smudges are visible: The cliffs of Guernsey, to the right; those of Herm and Jethou, garlanded with tinsel sands, to the left; and, between them, the Brehon tower, silhouetted. Signposting the Little Russel Channel.
Our leading mark for St Peter Port. Where the tide is falling fast. Leaving the inner harbour cill high and dry. Stargazer secures, on the waiting pontoon, until the arrival of the evening flood.
