An entertaining video of a family sail (2001) across the South Atlantic in a new Atlantic 42 catamaran built in Cape Town. The owner, Sib Reppert, was an experienced offshore sailor, competition rower, ex US Navy and a IP lawyer. Sadly Sib passed away after a brief illness in 2013. You will notice that when the boat starts sailing fast there is a very loud humming noise reverberating through the boat. This was due to a small, 4" wide, swim step on the trailing edge of the rudder that did not have the edge beveled as directed in the construction plans. A square trailing edge starts a resonant vibration that can get very loud. Simply beveling the trailing edge with a file stops it completely. An easily corrected "new boat" bug. Three parts, enjoy.

Interview with crew, September 2019

Enroute from Bermuda to Newport, June 2019, crew of two, sailing 20 to 25 kts under autopilot.

The new Atlantic 72 catamaran is a comfortable cruising and charter platform with great performance. All carbon construction by Aquidneck Custom Composites. Five double cabins, each with head and shower, plus crew cabin. Twin 110 HP shaft drive Volvo engines yield a comfortable 12 kts. under power. Easy sailing speeds in excess of 15 knots.

In 1995 I had the opportunity to sail the original HAMMERHEAD 54 trimaran from S. Dartmouth, Massachusetts to Nantucket island with Bill Shuman her owner/builder and crew Joan Welsh. Conditions were good for the trip, although more wind would have made it faster. Elapsed time was 3 hours and a few minutes. While the point to point distance is 42 n.m. there was current against us all the way which varied from one knot in Buzzards Bay to 2 knots in Vineyard Sound. Add in a detour around a shoal and a dog-leg through Wood's Hole the distance sailed runs about 46 n. miles. I've done this trip about 50 times in JUNIPER, my own 52' trimaran, never making better than 3 h 25 min. So 3 hours and 8 minutes was very good for our first try in Hammerhead. The video tape, as you will immediately be able to tell, is un-edited and includes a close up of my hairy leg. Please feel free to fast forward!!!! The fastest sailing is about 15 minutes into the tape. Chris White
