I my youth summer evening were often spent catching crabs on the South River at the point between Church and Crab creek. Brother Bob and I would meet our friend Mike in our respective outboards , raft up, toss out the anchors and some stinky old chicken necks attached to cotton cord with steel shower curtain hooks . In the course of a sunset we’d typically we’d catch a half a dozen blue crabs. Not many and hardly worth it form the standpoint of crab catching but the real value of the was watching the sun set in the company friends.
These days when cruising the Virgins, we like to take George, the dinghy, for a spin in the evening poking in an out of all the little nooks and crannies . You never know what you might find. We haven’t caught any crabs yet but we have caught quite a few sunsets … in the company of friends.
You’d think there would be a simple formula to calculate the power that a set of sails can generate in a a given amount of wind . But then you would be wrong. I did find the following after doing a little web search:
Wind of 7- 10 knots
HP = 0.015 x sail area in square feet
SeaSea has 18 HP
Wind of 11-16 knots
HP = 0.020 x sail area in square feet
SeaSea has 24HP
Wind of 17-21 knots
HP = 0.040 x sail area in square feet
SeaSea has 48 HP
Wind of 22-27 knots
HP= 0.070 x sail area in square feet
SeaSea has 84 HP
I also discovered that 10 knots of wind exerts 396 pounds-force on a stationary wall that has an area equal to that of SeaSea’s sails. I thought it would have been more. Yes pounds-force sounds weird but that’s to distinguish it from pounds, the weight and for that matter pounds, the currency . Imperial units can be super confusing when entering the world of physics. For those so inclined the above force amounts to 1760 Newtons. Sir Isaac, who sorted out the math, has the same birthdate as Jimmy Buffett making it all the more relevant to the island sailor.
If there was no friction to slow things down, applying those 1760 Newtons to SeaSea, or anything else with the same mass, would accelerate her at a rate of a little less than half of a foot per second per second. That translates to a 0 to 60 mph time of about 3 minutes and 11 seconds. Let the clock run, in the same frictionless world, and SeaSea will eventually reach the speed of light, where Einstein takes over for Newton . Albert’s birthday is, incidentally , the same as that of Billy Crystal, who has a great first name, and who probably knows someone who has been sailing.
Of course the above is over simplified and silly . There are too many variables. Friction exist, airfoils are not the same as flat walls , waves go up and down, fish fart, and seagulls squawk. Accurately calculating the horsepower generated from a set of sails is quite the challenge and probably futile, but if you really want to give it a go you might give this a look. Even here they are talking about force not power . Good Luck .
So my brother Bob is a realist. It fits, he’s an engineer and has been adjusting sails of one sort of another his whole life. Our parents somehow predicted his lifelong passion before he was born. Hence his name BOB , Butt On Boat.
Whether or not you are a sail trim fanatic SeaSea sails great.
Thomas was not really speaking of Cruz Bay, nevertheless , it’s probably not a great idea for a visitor to cruise by yacht into Cruz Bay . All those moorings are private, there is a fair amount of traffic, including that of the ferries and there really is not any dockage for transients. No worries. This lovely harbor with the best shopping, grocery getting and restaurants on St John has an ample dinghy dock . Moor around the corner at Lind Point or Honeymoon Beach and it’s just a short put-put to the bay . Bring a flashlight as you will want to enjoy the nightlife and will need it for the ride back .
This is SeaSea viewed form the beach of George Dog Island in March 2020. In the background is West George Island and Scrub Island . The dog islands are a small group of islands in the British Virgin Islands. They were named by early sailors for the barking they heard coming from their shores. This was, however, a case of mistaken identity as the sound they heard was not the bark of dogs but rather the yelping of the Caribbean Monk Seal. These creatures were valued for their oil and meat . Which, for them, is unfortunate as the last one was seen in 1952. After an extensive search for survivors they are now officially considered extinct.
For the vacationer the “Dogs ” offer fantastic snorkeling, diving and as you can see secluded beaches.
As crazy and complicated as our world can be , the notion that a dip in Maho Bay can put all those troubles to rest , is therapeutic. Just be sure to partake in the minimal effective dose and know that it is difficult if not impossible to overdose.

6/24/2020 . Sandy and I returned from the 10 day shake down voyage of SeaSea on March 12 2020. No significant problems . We are thrilled with our new boat. She is just about perfect and the islands are grand.
We return to the real world and … Surprise! It’s closed . What ? Yup . gotta wear a mask and not the snorkeling kind. If it’s not essential its closed. Can our charter guests travel to St Thomas ? Not really , might get a flight there , but if you don’t live there you can not legally check into a hotel , airbnb , or charter yacht so there is no place to stay . Yikes.
Fast forward to June 1 and the USVI finally opens to charter boats. By June 20 SeaSea has completed her first voyage with guests. We sincerely hope she took them on a fantastic adventure . Many thanks.
Not sure Ram Head is what Helen Keller had in mind when she said the above , but its a pretty good description of what this south east point on St John , USVI has been doing for thousands if not millions of years, standing over 100 feet tall and looking straight ahead across the ocean .
This viewpoint is from the end of the peninsula looking back at St. John. It is accessible from Ram Head trail which can in turn be reached from the road or one of the lovely moorings in the calm bays seen in the upper left corner of the picture . To the right is Drunk Bay . You don’t want to swim or anchor there but it’s only a short hike and is spectacular in its ruggedness.
