MARINE NAVIGATION

100. The Art And Science Of Navigation

IMG_3586Marine navigation blends both science and art. A good navigator constantly thinks strategically, operationally, and tactically. He plans each voyage carefully. As it proceeds, he gathers navigational information from a variety of sources, evaluates this information, and determines his ship’s position.

I have been asked many times for proof that the Murrelet can be considered ocean worthy. Until November of 2001, I was unaware that proof (outside of the mathematical ratios) existed. Because the uninitiated do not consider a trip across the English Channel, which is done by Mac26x boats, or a trip from Key West to Cuba, which I would like to do, or even circumnavigatingVancouver Island, to be an ocean crossing or passage it is difficult to convince doubters.

PHRF Racing

Murrelet’s potential as a racer was recognized shortly after her launch in 1999. The manufacturer even oriented its promotional literature around this potential. But racing organizations were reluctant to allow unballasted operation and it really wasn’t until 5000 hulls were launched that serious racers began to take notice of the one-design racing potential.

Primary Ballast System should be Water Ballast

James Boyd in his April 2005 Sailing World article (page 45) notes that the Vende Globe machines with canting keels also have water ballast. The question as to which is the primary ballast system on boats that have both may have been answered in that article.

Then, Now & Post Carbon

During the last 10 years, sailing technology in the Americas has made its greatest advancement since 1900. The US national park service provided some valuable insights in presentations made during the AC34.

Evolution then Revolution

Prior or to 2,000, multiple generations of family members slowly evolved fixed foil on center-line designs, moving the builds from wood, mettle, and cotton into carbon fiber, and moving ballast from the bilge to keel foils.

Remembering Hobie Alter, consulant to Coleman

hobieWe honor Hobie Alter who passed away on March 29th 2014 in simple ways. On my sailboat it is with a Coleman ice box. The only finished compartment on the MacGregor 26x sailboats is the place the manufacturer intended for that box, which stores a factory supplied Coleman ice chest.

Comfort and Water Ballast

It was pretty galling to watch the water-ballasted boats taking the conditions very much in their stride – and with significantly more comfort for their crews. 

The Cascails fleet exhibited a good representation of current offshore design, and it was interesting to see how they fared.

Ocean Cruising Comfort

I’m occasionally asked if I miss the larger, deep draft sailboat. The answer is always no. That type of craft now seems to me like a helpless one-legged seabird soaring above the surface of the sea, never able to safely land or seek shelter.

Water Ballast

bilge ballast According to Sailing Today, September 2000 page 83, Van de Stadt’s Dehler 25 sloop bested MacGregor Yachts by a year or so in the use of water ballast. The German Dehler 25s were produced from 1984 to 1991 and water ballast was reported in the US to be used for trailering reasons and cost savings.
