Zen 24 Hydro-dynamic performance

 

There is a great difference in sailboat performance. Some may look similar, but they all have different sailing characteristics.

Some sailboats are fast or slow, stable or unsteady at  the helm, tender or stiff and these characteristics become most evident in heavy conditions.

The Zen 24 realizes this integration with a new approach to hydro-dynamic hull design. As a result you feel smooth and easy sailing and you will enjoy sailing the Zen 24!

Zen24: Sail magazine, review

It is the day after the big boat show in Annapolis Maryland. Sail magazine had scheduled a Sail with us on the bay. We are here at the Chesapeake Bay and conditions were prefect. It had been raining and cold the last few days, so this was a taken as a gift from the Universe. The day was sunny, comfortably warm and moderate winds in the 11- 15 knot range. Light by the S.F. Bay standards, where the Zen24 has been sailing lately. No reef was needed today, this would give the Zen24 chance to show how she does under normal sailing conditions. The writer had already seen pictures her sailing under the pressure of San Francisco.

 

 

We got underway without issue and motored out of the marina and enjoyed the quiet view of some of the other show boats out doing maneuvers and the locals still at dock. Once out of the marina the ZenMotor was turned up a little, to show some speed and make some faster time out to open waters. Once cleared sails were raised and the ZenBoat leaped forward and quickly found a groove. It was as if she also had missed being on the water with the winds beneath her wings. Yeah, there is the groove exclaimed the writer!

 

 

After we had gotten things under way, the writer was invited to take the helm. We sailed back and both for a while the writer was impress with the nimbleness of the ZenBoat. She was quick to respond to command or wind. He noted that we kept up with a larger boat that we had come out of the marina with and was impressed with our speed.

 

 

After we had sail for a while we came across his partner on another boat. The plan was they were to film each other under sail. The other boat was a fast sloop about 26 ft. We mixed back, and along side of her, before slipping behind her to finish the photos. Then it was our turn, sails were trimmed for close reach and we leaned into the water and lifted in the wind. It was like growing wings as we pulled ahead.

 

Once done with our speed run it was asked what was the blue boat’s speed keeping up with us. We were told 7 Kts over land.

We turned and head back after a few pleasantries and jokes were exchanged. Everyone was pleased with the run.

The written once back in the marina under power put the ZenBoat through some drills, stopping, backing, turning, thrusting.

He was smiling with the pleasure of being impressed and a great afternoon sail. As the clouds darken with the change of weather settling on the day, we docked and prepared the ZenBoat for her trip back to Alameda.

Zen24 @ the Summer Sailstice…Alameda/Oakland

It was a grand and glorious summer day on Sat the 23. It was not the real summer solstice but it was the official celebration day for the summer sail event.

I had been contacted by Capt Mary of Afterguard academy to take a few passengers and join in the sailing event for the day.


I arrived at the marina a little early to setup the boat. I was surprised to find I had missed the boat. I felt like I was seeing my child, my boat after an absence. It did feel funny getting on it and standing with the boat moving so much because of it’s lightness, after just being on the stable ZenCat these days

The wind was perfect, we needed to reef for the Zen 24 but it was very comfortable after the sails were trimmed to the conditions. Unlike Sensei I was not trying to show how well the boat could handle stronger conditions. I just wanted a comfortable ride for my crew and me. When sailing you have a choice sometimes you can sail easy or rough.


Little by little we made our way out of the estuary. It was slow going. Not because I could not get speed but I was suppose to bring up the rear with the group and I keep needing to slow down in order not to pass the others. The Zen24 was faster than the other boats in the group.

Once out on the Bay we had a very nice sail, no tacking just a smooth ride. That part was fun. There were a lot of boats out and about over in the slot where the winds are more intense. We however were not going that far out because we were, suppose to be joining the parade. Therefore we headed back down the estuary after a bit. Another reason was we needed to make a pit stop at Jack London since the Zen Boat head is not legal to use here in the States as yet. This is one of the changeovers needed bringing a boat from Japan.


We made good time going back down the estuary since the wind was at our back. We stopped into Jack London for a quick bladder break, before heading down further to the summer Sailstice Headquarters at the Encinal Yacht Club.

 

There at the Yacht Club, we made passes in front of the judges stand to bring some attention to the Zen24. 🙂
Our next move was to head back to the Afterguard office. There we, mostly me put the boat away for the evening.

Afterward I headed back over to the Encinal YC. There with my Zen24 gear, I set about chatting with a few people and smouzzing in general about the Zen24



Announcements were made, awards issued, alcohol flowed, I left. It was a good day.
I expect this event to double in size next year. I hope to organize a Summer Sailstice event in Japan next year, under the sponsorship of AOKI Yacht club and corporation. We can get more involved with the international sailing community as well as raise more Japanese interest..
