Header Photo Philadelphia Tuckup



The previous header photo was of the reproduction Philadelphia tuckup, Marion Brewington, built by the Independence Seaport Museum. I lifted this photo from the Green Boats blog which unfortunately went dormant two years ago.

The Philadelphia hiker and tuckup were Americas first racing dinghies. Racing these catboats on the Delaware River was going full bore in the 1870s (which indicates that it was developing in the 1860s and maybe earlier) and continued to the early 1890s, when expanded commercialization of the Philadelphia waterfront shut down the tuckup yacht clubs and their boat houses. Following the lead of the sandbaggers, the unlimited hikers had ridiculous sail plans, carrying cat rigs up to 450 square feet. The  Marion Brewington is a fourth class tuckup which had reduced the sail area to a more sensible 177 sq. feet (but still on the overpowering side in modern terms), set on a gaff rig on a hull of 15 feet in length. The fourth class tuckups were normally crewed by two. The two hull lines of tuckups that have made it to the present day, the Thomas Seeds and the Spider, are both fourth class tuckups

Ben Fuller put together a very interesting history of the hiker and tuckups in issue #148 of Woodenboat, pages 46 through 53. Well worth a read if you can get hold of a copy.

The famous and somewhat controversial American painter, Thomas Eakins, painted the hikers in his well known Sailboats Racing on the Delaware (1874).

HYC Cruise Day 6 July 30 Lay Day in Block Island

Blasts crew rented a car to tour the Island, by day, dined at the National on a gift certificate and reported that it was excellent.

True North remained aboard during the day to make sure their anchor was holding in the big winds and came in for dinner at The Oar. 

Everyone from Ohana and ILENE (except Ilene) rented bikes from Aldos at the Boat Basin for the big loop of the southern half of the island. First major stop was at the beach at the foot of Mohegan Bluffs. 

There the younger generation went for a swim while Bennett and Roger took a long walk west along the beach. I dont think I have ever been there at low tide before. It reveals where one can swim without fear of being crushed against submerged rocks by the breakers. Then a brief stop at the lighthouse for liquid refreshments as defense against dehydration. There we learned of the imminent plan to build a "U" shaped cup of windmill generators around the southern end of the island a mile or two off shore. We had lunch at Finns, where Bennett satisfied his craving for whole fried clams and Roger ordered this new (for me) treat too. Then marketing at the very pricey local market before returning the bikes -- 1.5 hours late for a half day (4 hour) rental but they did not charge us the extra ten bucks -- and we dinked back, except for Rolo and Chris, who went to the beach and returned by launch later

Dinner on ILENE for eight: from Ohana, ILENE and Shanghai. A weird assortment of foods that somehow came together magically.  A rain shower required us to migrate from the cockpit to the cabin. CJ enthralled us with stories from his interesting life. We eight were from China, the U.S., Guatemala and Denmark, and included speakers of about ten different languages.  Most of our dinner table pics are after the meal; eating seems to always take precedence over photography until plates are empty.
Rolo, Christian, Laura and Bennett

Jenny, CJ, Lene and Roger
Shanghais dink motor failed on the way over so they came in tow. And I towed them back. Maybe we can create one fully operative dink between Shanghais inflatable and Ohanas outboard. But, in fact, it appears that all of the places both boats intend to visit on their ways back -- yes we are at our furthest point away from City Island -- have either docks or launch service. The other alternatives are the blissful solitude of staying aboard a well provisioned boat or getting a lift from strangers.

Stay tuned.

April 20 Beaufort SC to Charleston SC 57 2 Miles

I forgot something that happened in Beaufort, probably because Id rather not remember. While we were in the theater we heard a loud storm going on outside. Some water came into the boat through the mast boot but that was easily picked up. I learned to dispose of a used American flag with respect. We had retired one at the beginning of this cruise which had been torn to tatters by the wind. But the wind tore our newish flag -- and its flagpole -- off from the boat. I will figure out a more secure way of attaching the next one.
Yes, I know I said we had decided to anchor in the Stono River, just short of Charleston, but our speed was so good today that we made the 3:30 opening of the Wappoo Creek Bridge and never had to deal with the fact that if you dont make the 4:00 opening, you have to wait until 6;30. It seems by dumb luck, we had favorable tide and the deep water of high tide most of the nine hours we were underway from 7 am to 4:00 pm. The favorable tide is proven by our average speed - 6.3 knots.
I have thought of several additional reasons why it is impossible for that hypothetical Ph.D. to figure out a tide algorithm. It depends on where in the river you sail: in the center the tidal flow is different from nearer the sides. It varies during the six plus tide cycle, slow at the beginning and end and fast in the middle. At bends in the river, one side flows faster than the other. And when you add in motor-sailing, as we did all day today, your speed will depend on the wind direction and speed which vary from minute to minute, relative to the boats course which was a near continuous curve, and on the diligence and skill of the trimmer. Today the wind was generally from near our stern and the small jib self jibed many times, as it is designed to do. I hope to never mention that crazy hypothetical algorithm again.
It was a cool but not cold day, warming up in the afternoon, with hazy sun poking amidst the light clouds. No rain.
We had two small problems near the end. I bumped into the throttle lever while walking past the binnacle, decellerating our RPMs and bringing back the "alignment" problem that we hoped we had fixed. The rattle was back and big time. But coming to neutral and building up the RPMs slowly -- the rattle was gone again. Something is still wrong and needs to be fixed. Shortly after this I think I caught a crab pot float on our rudder. The wheel became very heavy to turn and our speed was considerably slowed. I think that a crab pot was the cause of the problem but we dont really know. I turned the boat several times and slowed her and if it was a crab pot float, it fell off.
One of the crew at work, doing what he does second best (first is eating!)






















Here is Charleston from our anchor on the Ashley River. On our two prior visits here we took a dock at an excellent marina on the Cooper River, on the north side of town, which was full tonight. But we had no plans for sight seeing this time and did not lower the dink.

We have also determined, subject to plans D, E and F, etc., tomorrows (and the next days) passage: to the Masonboro Inlet and the anchorage of  Wrightsville Beach. At 6.5 knots this will take 24 hours, anchor to anchor. We plan to leave about 10 A.M., with favorable tide flushing us out. Decent wind from the west is predicted.
We have also determined our planning deadline for arrival back in NYC -- June 7. Lenes niece, Barbi, and her son, Trevor who we hung with in Amsterdam last June, are visiting and will arrive on June 10. We would like to get home a few days earlier to get settled and unpacked, and those few days also serve a second purpose: as a buffer in case bad wind prevents the Atlantic overnight up the Jersey coast, as it did when I helped Jim bring his 26 foot "Aria" up in about 1996.

Optimist Building in Virginia Beach

Al from Virginia Beach writes in and shares pictures of his project boat...

NOTE: ALS UPDATES CAN BE FOUND AT THE TOP UNDER PAGE TITLED "Virginia Beach Optimist Project"

Im building the boat for 3 and soon to be 4 grandkids. I sail and my 2 sons sail, so getting the little ones into it makes sense. The oldest is 8 but lives about 300 miles away, so when next summer comes and we get to our lake house hopefully the craft will be ready to use.

Im using West System to coat and put this together but am not glassing the boat - extra weight that I dont want or need. My boat is Maranti plywood, 12mm for the transom etc and 6mm for bottom and sides. Ill make my own foils from 12mm also.  For the "solid" wood I have found some very nice and cheap spruce. I plan to use some mahogany for the rub rails - I have some nice pieces. Almost at the point of fastening things together since today I got the chine bent and straightened - that was fun and am glad I had as many clamps as I have, but one never has enough clamps!

Steps:

I fished a piece of spruce out of my pond and tried again with bending a chine.  I figure that 24 hrs underwater with all the enzymes and slop in my lily pond should make it pretty bendable.

I clamped the stern and mid ship positions and placed the above type clamps to make it parallel.  Then I gently bent the end of the chine toward the forward bulkhead and did two things. First I used a long clamp around the chine and the nearer stringer. Then I hung my tool bag with saws, drills and assorted heavy items on the end of the chine. I never changed the weight but I applied the straightening clamps and gradually tightened the long clamp.



The whole process took no more than 45 minutes and I never heard a creak from the wood.  When the chine was finally in position I removed the long clamp and tool bag and attached the chine to the forward bulkhead with a clamp. Not a screw in it yet. I will let it dry for a few days before removing clamps and attaching with screws. Then Ill see how the skin fits.

The Garcia Exploration 45 Jimmy Cornells New Boat


Aluminum Boat Building Is Alive And Well (in France)





Allures and Garcia Yachts http://www.garcia-yachting.com/ were well represented at this years Annapolis Sailboat Show. With the Allures 39.9 and the Garcia Exploration 45. In this review I will be discussing the Exploration 45 built by Garcia Yachts. Also known as Jimmy Cornells New Boat.

The Exploration 45 was designed with the input of veteran sailor, voyager, and cruiser Jimmy Cornell. The design comes from the board of Berret Racoupeau Yacht Design.





Even though this is a new design, and something I have not seen before, it does have something in common with other Garcias and the Allures Yachts a centerboard with twin rudders. This design makes for a very efficient sailing design because one rudder is alway vertical under sail. At slow motoring speeds having the twin rudders without the benefit of prop wash can make this type of design difficult to maneuver. The Expedition 45 solves this problem with the installation of a bow thruster. I was impressed with how well the boat maneuvered in the tight confines of the marina. With a draft of 3.44 with the board up and 9.14 board down shallow water cruising opens up a new world not usually visited by monohulls. With the board down windward performance is better than you would think of a centerboard yacht. As with all boats this design is a compromise of shallow draft and windward preference. It is a compromise I can live with! In our sail off of Annapolis, Maryland in 15-20 knots of wind we obtained speeds of 7-9 knots. The Exploration 45 handled well, which was to be expected of the design. In the afternoon the wind continued to increase and we decided to put a reef in the main. The process went with out a hitch. Over all, sailing this boat should be very easy for a couple.



One of the most impressive features of the Exploration 45 is the navigation station. The navigation station is located in the forward saloon. This allows great visibility out of the house windows. I was impressed in the fact I was able to see over the bow from this position. The interior was easy to navigate underway and comfortable. My only complaint is the limited access of the engine which is below the sole at the companion way which could make servicing the engine underway difficult. I found the filters and strainers were easy to access. The cockpit felt safe and comfortable. For the watch there is a safe place to sit behind the house with the chartplotter/radar within easy reach.

Down Below Underway


What about the construction? I took a very close look at the construction of this yacht. I am thankful that the Builder and Swiftsure yachts allowed me access to the bilge and systems areas of the boat.
I was very impressed with what I could see. The metal work stands out on Exploration 45. The hull is fair, the welds are well executed, and the hull to deck edge is beautifully done. The cabin top is made from fiberglass composite. The aluminum decks are covered with cork decking to give the appearance of a teak deck. The footing of this deck is very good and it feels good on the knees.

Hull Framing


I would very much enjoy finding myself hundreds of miles offshore, watching the miles tick by on an Exploration 45.

With Allures and Garcia Yachts being marketed in the USA by Swiftsure Yachts http://swiftsureyachts.com/garcia-exploration-45-2/ 
I hope to see more aluminum boats on the water here in the states. I look forward to when these yachts are on the used boat market and I find myself surveying one.

Header Photo Balmain Bug Aussie Historical 6 Foot Skiff

Australian Historical Skiff




The previous header photo was of the "Balmain Bug" a 1994 reproduction of the Aussie 6-Footer Historical Skiff Class. Aussie Ian Smith built her and she is shown on the dock sporting her light-air rig with a boom at least over 2 times the length of the boat and a bowsprit approximately 10 feet long (3.19 meter). Talk about being over-canvassed. The 6-footer class takes the cake for being the craziest of the crazies!

Quoting from the seminal book on the history of the Aussie skiffs, Bluewater Bushman by Bruce Stannard [1981];
"It is believed they were first built at Balmain in the 1890s and although they were first conceived as childrens boats, there is no doubt that they demanded the strength of three men who were courageous, good swimmers and had the strength and agility of circus acrobats...They carried a staggering 1000 square feet of sail including a main, jib, topsail, spinnaker, ringtail, and even a watersail. [Mike Scott, over in comments, defines watersail as..."hung below the main boom to catch that extra drop of wind.....almost drooping in the water....hence the name....!] With so much sail up and so little to support it, it is hardly surprising that the 6-footers spent a lot of time "in the gutter"....
The class peaked during the early 1900s, attracting numbers because it was the cheapest way to go racing. Here are some photos of the early 6-footers sailing around 100 years ago. [Found on the Net]


The original crews sailed the 6-footers upwind with the bowsprit plowing a furrow in the water; probably the only way they could balance the whole package upwind.


Now for photos of the modern 1994 Smith reproduction 6-footer. A picture of the "Bug" off-the-wind in a fresh breeze, shortly after being launched. Looks like the crew is trying to get to the back of the bus when reaching but, alas, there is no back of the bus.


After ten years out of the water, the "Bug" was relaunched in October for this years Balmain Regatta.

A quote from crew Campbell Reid:
"Even though she is based on a design close to a century old you can see how for their time these boats were pretty high tech...She will bury her bow in the blink of an eye but we were impressed at how seaworthy she was and were really happy that we could get upwind pretty well. In the six foot division of the historic skiff fleet at the regatta we think we are a serious threat.

 The precarious crew position Campbell Reid finds himself on the foredeck/bow may be the most comfortable one in drifting conditions. [The next two photos pulled from the Balmain Sailing Club website.]


Stick two grown men into a 6-footer and the scale becomes obvious. A 6-footer becomes a true "micro" dinghy.


The obligatory GoPro video shoot from this years relaunch. The bowsprit is so long it gives a perspective of a much larger dinghy. The 6-footers, like her bigger historical cousins, sported canvas lee cloths in a vain attempt to keep the water on the outside




A more recent 2015 video of the Bug including flying a good size spinnaker without driving her under. (Came pretty darn close though!)

January 20 Pumpkin Key to Rodriguez Key 27 7 miles

It worked like clockwork. The alarm got us up at 6:30 and after coffee we were underway at 6:50 and Angelfish, which we feared, was easy; no soundings of less than 8.2 feet. We were through it by 7:50.
The tide flowed strongly against us in the Creek, with surface eddys swirling, as in the East River back home, and the wind in our faces, both of which slowed us down, which is good if you fear a grounding. So you can chalk us up in the group that holds that Angelfish is doable in a 5 8" draft hull. (High tide was at 8:10.)

Once out in Hawk Channel the depths were in the teens and we ran under Genoa alone at speeds of up to 7.5 knots with the wind a bit forward of the port beam. Yes, we actually got to sail!!!  Yesterday and today we were greeted by dolphins again after a long absence from them in Dade County. Hawk Channel is wide and marked by buoys.

We were anchored behind Rodriguez Key by 11:30 am.  The key is a big uninhabited, wooded oval l.8 miles long and 1/4 mile wide, which lays east to west. It is a nature preserve, girded by mangroves, with no apparent means to reach it by land, sea or air. On its north side, between it and Key Largo there is room for a hundred boats to anchor in 7 to 9 feet of water. We were the only boat here when we arrived, later joined by eight others. The winds were from the SE and hence the key provided little protection from them or the waves they kick up, but mild winds were predicted for the evening and night.

We were here so early that I wondered if one could tie up a dinghy on Key Largo (Spanish for Long Island?), a mile away. Yes, but only by the payment of $20! My curiosity to explore a bit of Key Largo was not that strong. We also thought to play with the SUP which has not been used since we rented it back in Miami Beach. But the day was not pleasant, cool, grey over head and showers predicted, so we did not do that either. And not many chores -- a low tie of the genoa to its roller furler was redone, as was the lower tie of Old Glory to her staff. The hose from the gas tank to the outboard now works again. I am so lazy these days. reading, writing and laying around. Is it possible that Im slowing down?
