SV ROSIE G

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 form core and vinylester resin.  

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 is very light with carbon battens from RBS Battens and head spar (under 150 lbs). 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  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 three foot square opening hatch brings the outside world in when at anchor, and serves to load large items if desired. 

We have eight 170W panels, four make 48V for the motor, and other four are divided to charge to separate 12V house battery banks.

In the bow, there is a 100W panel for the battery system that runs the windlass, forward cabin lights, headlights and washdown pump.

Aft there is a 50W panel to charge the battery system that runs the electric winch, compass light, stern light and cockpit 12V outlet. 

All of ten our panels we bought from

Sun Powered Yachts.

All are run through Victron charge control which we can monitor through bluetooth.

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.
