In concept the 29ft SATURN is an updated Surfsong, or a fast Gypsy. It is suitable for those who want to coastal cruise or occasionally race. It is not intended for long term ocean sailing as it has limited load carrying and overloading would spoil its performance.

To speed construction the hulls are chined flat panel and the decks are all single curvature. Construction is plywood on frames, epoxy glass sheathed. Saturn can be built in sections for final completion by the water.

The photos above show the first hull completed and out of the workshop and below is the beginning of the central cuddy

"Went round Hornby island in two and half hours last week. deep reef in main and a couple of wraps in the jib, just flying but very comfortable. OK, it was a little wet going to windward at 10kts but dry going downwind at 15kts. I'm liking her more and more.

On December 28th Andrew Slow wrote again from British Columbia (where of course it was mid winter) to say:

"I've been sailing quite a bit though and like the boat more and more as I get to know her. The day after Boxing Day I took my kids and their partners out for a windy sail in relatively flat water. With a reef in and a few rolls in the jib I guess we got up to 17kts or more very easily going to windward with no fuss at all. They were very impressed and said they could water ski behind if they had the nerve and a very thick wet suit."

I have enjoyed the boat so much this year and feel that I know it so much better and know what it can do. I think I will have her until I can't hop about anymore"

See photo and video below when racing in British Columbia. The boats to lee while sailing to windward are larger Farrier trimarans, as you can see, we're going at much the same speed. Then the boat to lee when we are under spinnaker is a Santa Cruz 52, and we caught it up! I tried to video the gps, not very successfully (I was supposed to be trimming the spinnaker) but it does show 13 knots

A video is here 

And this is a Florida built Saturn, nearly finished!

Later:"launched the boat this morning, thanks so much for a great looking boat,"
