hard water sailing

Michigan, as well as most of the Midwest, is in the midst of the polar vortex – with horrific cold temperatures and wind chills approaching -40 degrees F (and C, coincidentally…).  seems appropriate to share a sweet drone video of the DN iceboat North American Championship racing that was held recently on Lake Charlevoix in northwest Michigan.

JFK: we are tied to the ocean

I love how JFK had such a passion for the sea and for sailing – particularly small boat sailing.

(although his halyard could stand to be tightened a bit to get that upper spar up closer to the mast…)

the joy of tiny sailboats

an interesting video about malay jongs – tiny little sailboats.

jongs

For centuries the Malays in South East Asia have been racing jongs, or miniature wooden sailing boats. The sport has been dying out in recent years, but volunteers are determined to keep their tradition alive.

points of sail

here’s a nice points of sail diagram, with a bit of humor mixed in!

ins & outs of ratchet blocks

here is another really cool video by Harken to visually demonstrate how their ratchet blocks work to reduce the load that your hands see for holding lines that are trimmed often (so your mainsheet on a Sunfish, and spinnakers or jibs & other lines on other sailboats).

they use a load cell (or load indicator) on the line going to his hand to show the load reduction that occurs with a ratchet block.  a key note: the load required to trim (or pull your sail in) is the same as without the ratchet system, but the load required to ease or hold the line is reduced (quite a bit) due to the ratchet block mechanism (a combination of the “stopped” sheave and the grooves that increase friction).

Sunfish sailors often use one of the following blocks for their mainsheet control:

I’ve traditionally used the 2135 (shown here on my mainsheet controls upgrade post), as it is usually cheaper, and the switch is usually easy enough to reach if I wanted to release the ratchet mechanism to allow the line to run freely.
