Yellow Seaclipper 10 Trimaran BANANAS

Multihull designer John Marples, from Searunner.com, sent me the following photos of his newly built Seaclipper 10 trimaran a few days ago. As you can see, it’s appropriately named BANANAS.

I love this little design. (Wish I had one myself).

Anyhow … the occasion for this photo opp was preparation for a feature about the Seaclipper 10 trimaran currently being prepared by WoodenBoat Magazine. As a matter of fact, BANANAS may even be on the cover … although I’m not 100% sure about that.

A boatload of guys (pun intended) have built their own Seaclipper 10s over the years. And a recent resurgence of interest in backyard boat-building has sparked new interest in Mr. Marples’ “easy to build” small tris for guys that want tough boats that are proven performers … without having to spend an arm and a leg.

John told me that a dad and his son (in Washington State) built one of these boats in about 100 hours. That seems to be the standard for this one. And all types of sailors, from novice, to experienced (like the one in the following pics, who has spinnaker handling skills) seem to have a blast in them too.

The sailor in these photos, by the way, is a young woman named Stephanie Evans. Stephanie emailed me right after this post went up and shared the following …

“I grew up sailing in South Africa with my family and sail 5-days a week out of the Berkeley Marina during the sailing season. I primarily sail for pleasure (and volunteer my time as an instructor) with Cal Sailing Club, and am a Sailing Instructor for Cal Adventures through UC Berkeley.

John’s Sea Clipper 10 design is very practical and just plain fun. Using pedals to steer freed my hands to to adjust trim and sail shape to my heart’s content–all lines feed to the cockpit. She pointed much higher than I expected and handled some fairly large tidal waves I encountered in Raccoon Straits (that would normally easily capsize the dinghies I sail) very well. And she surfed like Californian :)

I’ve read through more of your blog and I can see why people love these boats! Bananas was my first small trimaran sailing experience and I’m definitely going to try and get some more water time with this design.”

John Marples Built This Seaclipper 10 Trimaran & Named It BANANAS



  1. very cool. nice to see some other people figuring out what a great little boat this is. it looks like John has put more flare into the main hull than my older boat has. I’ve got the spinnaker, but never rigged it. I’m loving my junk conversion too much right now to play with it ;-)

  2. This looks like a great project, where can I get the plans to build this trimaran.

  3. Where can I find plans for the Searunner10?
