In 1977, while living in the little yellow house by the River Vaipoiri, a different boat came to paper and then lived on as a dream.
We had SEMINOLE anchored off the river mouth. She was a fine vessel, built with love and attention, cared for, and well sailed. When we started her we were sailing savvy but naïve about the sea. We chose to build a ‘traditional’ design, from cheap plans in a magazine. The Atkin’s ‘Ingrid’ design would turn out to be wet and slow, and after sailing her for several years there were endless thoughts of how to do it another way, even to the point of threats to take an axe to the interior and start fresh.
Patrick Humbert was my friend though all of the adventure beyond the end of the road. We lived the barefoot vagabond life and dreamed of new boats. His own was lost on a Tuamotu reef so his madness was driven by being boatless. We would spend lazy hours in deep discussion about making boats with the fewest moving parts, the simplest of everything, and even limited use of metal. West System was getting rolling around then and boats of laminated wood and epoxy were getting popular and easier to build. So we drew dreams of cargo space, deck living, shallow draft, up-the-river kind of craft. The junk rig was logical and would be cheap and could be repaired anywhere with just about anything you can find. There were asymmetrical lee-boards externally like Dutch canal boats. We even fantasized electric power or none at all. All a little crazy for 1977. (If you're interested in reading the story, there is a great book "Dear Mom, The Bare Chronicles.")
In 2014, an early sketch reminded me of all the reasons why Patrick and I had tripped out on the different concept. Lots of quick drawings evolved until the scale ruler and drafting sticks became necessary. Lines and sections could be used to develop a design from a crude but experienced guess. We drew and erased and worked up to a scale that helped make it easier to visualize. When it looked real enough I called Jim Antrim because we had earlier meetings about other boat fantasies. He’s a patient fellow, and I knew there was no shying away from unusual design projects. Jim having designed Patrick’s TE MARAMA catamaran was a real connection also.
We found a fantastic guy, Cree Partridge, owner of Berkeley Marine Center, who was willing to build the Rosie G, and as of January 2019, molds were being made for the beginning process.

Fifteen years ago, a red cloud kelpie was born in Western Australia. Originally a desert dog, Rosie came to Maui, Hawaii when she was two in 2006. She adapted to island life including sailing on SV Cornelia. She quickly took ownership. Over the nine years we've had Cornelia, it was becoming more difficult for Rosie to get on and off, and down below.
Rosie wanted her own boat. The SV Rosie G.
She wanted her own blog to take you on her boat building journey. She also wrote a book called Rosie's Perspective, Dog Only Knows.

Rosie was getting on, like all of us. And like us, she wanted to get on and off easily, walk from the cockpit into her doghouse without climbing over anything, go "down below" in two easy steps.
Rosie had a great life, spending almost 10 years being on a boat. She passed over the rainbow bridge Saturday, 18 May 2019, the first day of her 16th year. While she isn't physically with us to see her boat get finished, she told us before she left us she would definitely be keeping an eye on the progress of her boat.
Rosie don't roll!
The SV Rosie G will be stable, go fast and be dry. There won't be any wires to trip over on deck. And it will be roomy inside, plenty of places to find comfortable cubbies to snuggle into for a nap.
Designed by Jim Antrim and built by Cree Partridge of Berkeley Marine Center, it is easy to board from a dinghy or swimming. The hull and structures have the finish of a good quality commercial fishing boat built on a male mold using CoreCel and glass/epoxy.
Scow Bow provides a soft ride, dry decks, long straight waterlines, massive volume and high stability.

The main (and only) sail is a ‘junk’ style. The sail will be very light with round carbon tube battens, boom, and head spar. Modern spectra sheets and halyards and ‘soft’ construction details make the sail easily set with the single electric/manual winch.
Instead of woven jute or hemp panels, bamboo battens, solid wooden masts, and coco fiber lines there is a sail made from varied weights of Dacron material, battens made from windsurf masts of 100% carbon, a tapered carbon tube mast from GMT Composites with sheets, halyards, and control lines running in the lightest blocks and fittings. It’s very winglike and controllable, lightly loaded, all sheeting from the leech, full twist control with low tension.
The entire sail can be swung on the mast to ‘square it and balance the loading, thereby helping to balance the boat. A junk rig has few parts and low loads. It is uncomplicated and easy to fix anywhere, no rigging to fail, infinitely adjustable and makes totally aerodynamic sense if you understand all
power comes from angle of attack.
The ballast keel, from MarsKeel,
is 7405 lbs of pure cast lead with
3% antimony and keel bolts are
316 Grade Stainless Steel.
The keel can be grounded
and stand the boat.
The perfect grounding shoe.
The cockpit and the galley/nav/dinette are on the same level... no ladder... and the doghouse windows open to make the space airy when cooking, eating, and hanging about.
Volume forward in the beamy shape creates a huge space (appx 13’ x 8’) that can have any choice for use, from light cargo to private cabins.
A four foot square opening hatch brings the outside world in when at anchor, and serves to load large items if desired.
QT20 is the electric power plant (20KW) and has excess power for necessary maneuvering.
The Max Prop can be feathered for lowest drag, or tricked into staying in reverse, which will charge the MasterVolt batteries using the
motor regen capability.
At the core of the electric dream is a small fuelless generator made with Neodynium 52 magnets and copper coils. When there is a constant supply of electricity available there are endless options for comfort and safety.

COPPERCOAT is possibly the most powerful and long lasting anti-fouling available today. Developed in the 1980’s and available to the public since 1991, COPPERCOAT successfully protects tens of thousands of boats saving their owners time and expense.
COPPERCOAT is the combination of a specially developed zero VOC, water miscible epoxy resin and 99% pure copper powder (not cuprous oxide). Each liter of resin is combined with 4.4 lbs of ultra fine atomized copper powder, making COPPERCOAT the strongest copper based anti-fouling available. Indeed no other anti-fouling exposes as much active copper to unwanted marine life as COPPERCOAT.
The average COPPERCOAT customer world wide gets about 10 years of protection before they need to do their first touch-ups. That doesn't mean 10 years is a magic number; if you are in a mild fouling location it might be 12 years or more before you need to do anything. And if you are in a high fouling area and using an aggressive pad to clean the waterline it might be only 9 years.

Unlike what might first come to mind, their process of producing pictures on glass, metal, wood, acrylic or any rigid substrate is not about taking a printed photo and doing a standard lamination onto the surface nor is it about encasing the photo on/in acrylic sheets. Instead, the photo is printed directly onto
the substrate via a Flatbed UV Printer. The
end result is an affordable masterpiece,
just like SV Rosie G's sail
