Building a stripper dinghy

There's really no question in my mind between inflatable and hard dinghies. One is a boat and one isn't.
That's not to say an inflatable can't be utilized as a tender and be a convenient accessory. It's just a more temporary displacement device. Climbing aboard a rubber bubble in a chop never quite works for me. Rowing against a breeze will challenge either type, but I'll get there sooner in a solid craft with a hull shape that works in the flow of water.

The second major consideration in dink choice is power. Blowing the budget on the Mother ship precludes shelling out for an outboard motor for several seasons at least. That and the avoidance of gasoline fuel storage and transport issues is a big plus for me. I also actually like to row, for a while yet, anyway.

All that rationalization and a pile of surplus basswood, along with a mahogany plank end just perfect for a one piece transom lead me to build a dinghy over the winter of 2013. Juniata was 200 miles away under her dirty shrink wrap and snow. I had room in the shop. What the heck?

Starting with the transom shape, I drew a midship station and several forward sections and set them up with thin splines to visualize the shape.



The hull was to be formed with basswood strips. From a run of a picture frame molding I had 1"x3" off cuts. These were dressed, ripped and thickness sanded to 3/8"x 7/8"x 11' long. The total ended up being 45 pieces per side. Over 1000 feet when you include a few breaks and defective pieces.

The adhesive is West System Epoxy with microfiber filler. The strips were buttered up and pinned to the forms with 6d finish nails. The practical limit of stable assembly worked out to about 6 pieces per batch. Clamping at the stem was the biggest problem. After a few rows of fumbling with clamps and goo, an alernative had to be developed. The stem form block emerged from the scrap pile shortly and worked like a charm as the angle of the strips against the stem rabbet held them against the previous row as soon as they were pinned to a form. Clear packing tape protected the form block and the station forms from the adhesive.

Dealing with the twist required of the strips as they turn the forward sections was the next issue to develop.
If there were no limits on clamping and I wanted to steam the strips I could have continued to apply the same section pieces. However, in the interest of stability and the easy route, I opted for a cutting a taper on the forward ends. These were pulled through the table saw in an entirely 19th century freehand fashion not to be recommended and smoothed with a hand plane to 'epoxy tolerance'. That is to say a medium gap that leaves plenty of room for thickened epoxy, which ensures a good bond and adds some rigidity to the final product.
The resistance to twist results in a stairstepping of the strips. The worst of these received another mini strip to fill the corner before the adhesive set. After the taper program was adapted the rows worked in much more smoothly. So much so that I recut the starboard side bow area to regain the more gentle bending loads. Needless to say, an opaque painted finish was planned from the beginning, as epoxy needs protection from UV radiation.

Closing in.
The keel strip was 1/2"x 1-1/2" mahogany, bonded to the tramsom and the stem before any strips went on. Turning the garboard I used thicker, narrower strips to be carved in later. After the hull was flipped over I layed in a wider beveled kelson board for strength and to fair the interior.

And now the sanding begins. Nails were pulled and high spots knocked down with a hand plane, the basswood's mild nature made sanding fair a relatively easy task on the exterior. On the outside the glue got scraped close as a matter of course before it hardened. The interior was inaccessable and subsequently a mess of hard epoxy dribbles. Using 4-1/2" angle grinder with 40# cut it well enough, but the compound curves made a tricky job of it. After the grind, interior surfaces required several curved blocks and lots of grunt work to knock back to fair. Some strip built boats use a cove & round edge profile to register the strips and leave a more fair surface. If and when I do this again, I will jig up for edge matching and the taper.

Sanding begun

Medium density filler applied

For the first fairing coat I used west's 407 low density filler. I wanted the strength for filling any open joints and remaining step corners. After glass, I applied a final fairing coat using the microlight 410 filler and a plastic longboard sanding tool.

Two layers of 6 oz. fiberglass cloth are on the outside, one layer on the inside. All wetted with West's 105/205 resin.



The skeg went on between glass layers and received two more layers of its own.

Weighing in at 68 lbs. before seats, rails & paint.

Right side up for the first time.

I had to patch a little bit of barrier coat on Juniata, so the balance of the quart Interlux kit went to a first coat on the dinghy. This sanded out very nicely and I applied two coats of Petit Easypoxy for the final roll & tip finish. 


In the tradition of advanced mathematics and empirical design I pitched the new boat in the back of the truck and dropped her in a friend's pool to plot the waterline and seat locations perched on a milk crate. 

Blue, but not the Caribbean, yet...

She rode nice and high. So much so that I cut a deeper sheer in before laminating on the mahogany rub rails.
For the painter I wanted a simple grommet around the stem. To avoid exposing the basswood core to water, I drilled for some 1/2" water hose and potted in short pieces at the bow.

After her first season, still looking good.
She has performed admirably during her first season. Two of us and a week's worth of provisions and Stuff can still handle a choppy row out to the mooring and remain dry. And in smooth water she is just dream to glide along in. Decent oars just a bit longer will be the icing on the cake.

Enjoy.

Bringing her home.

Plotting our delivery trip from Connecticut through New York City and down the New Jersey coast involved some research of current and tide information. Looking for the East River transit to occur in daylight, preferably morning hours pointed to a 2 day window recurring at two week intervals. We settled on the May 6-7, 2013 and made our plans.

Over the winter I had been building a dinghy, stripper style; adding a few rows a day here and there. After the fiberglass and sanding and sanding and sanding,  I just managed to get the hull painted and the seats installed before loading it the back of a one-way rental van. We filled it with the C-head, bedding, our flotation & weather gear to head up to Norwalk. We stopped at Linthicum Sailmakers on the way up to pickup the new bimini top, built to match the old top and accommodate the original side curtains and clear dodger panels that were still in good shape. We rigged the bimini on arrival and the cockpit seemed cozy and protected.  Juniata was riding fine in her slip and the bilge pump only spurted a bit after three weeks of waiting.


We heartily recommend "Molcajete" in South Norwalk on Cinco de Mayo for dinner or take-out. After dinner we provisioned at an unusual market called Stew Leonard's. I'm not sure a description here could do it justice. Think Trader Joe's does Hee-Haw. It's styled as a farmer's market with entertainment in the form of past-their-prime Disney jingle singing automaton farm animals. My personal favorite sideshow was the live web cam of the company farm on a big screen TV. At 10 pm the plot was a little thin and dark.

Monday, May 6 departure. Myriad tasks.
Drive to town to get another pair of oarlocks; the first pair didn't make it into the truck.
Pick up some christening champagne and normal beverages.
Install oarlocks and lifting eyes in the dinghy.
Return the rental truck across town and a cab ride back.
Name the boat, apply graphics.
Bend on the sails.
Fill water and diesel tanks.
Pay the yard bill; ouch.
Shove off.
The weather was clear and calm, 65 degrees at 4:15 pm and we had a smooth motor to Manhassett Bay, picking up a town mooring ball about 7:40. These are free the first night.




The weather forecast for the New Jersey coast was not optimum. Several days of strong easterlies had raised a 4-6' swell. Winds were expected to drop, but temps were to be in the low 50's and rain percentages were still a concern. I had a few places to hide in mind if conditions would become uncomfortable. There's a protected anchorage behind the Statue of Liberty, and Sandy Hook offered some protection from the east. We couldn't count on any marina access until Manasquan due to the massive destruction of Hurricane Sandy. Underway at 0800, we headed for the East River. The transit was smooth and uncomplicated. Juniata was able to hold between 6.5 & 7 knots through the water which let us keep up with the commercial traffic. A tug & tow came through behind us and we held our distance without cramping them too much. Listen to VHF 13 for the duration of this run. Commercial captains appreciate knowing that you are aware of them and what their limitations are. On the home front, when I've been overtaken in the C&D canal, I have pulled a U turn to let the tugs pass and received more than one hearty thank-you as I turn again to fall in behind them.



 






New York harbor was quite busy with ferry traffic, but almost no wind. We crossed to the eastern side of the channel, cruised in close to the Statue of Liberty and down the harbor to Verrazano Narrows. there was only a light breeze from the east as we passed Sandy Hook and the swell was down to 3-4'. With the mainsail up the damp breeze steadied the roll enough to be tolerable. Light fog came and went throughout the afternoon cut visibility to less than a mile. We were glad to have radar up and running. Juniata rode the swell and the still incoming tide through Manasquan Inlet about 1630. I had reserved a slip at Hoffman's Marina. they are eager to please if a bit pricey at $3/ft plus electric. A note about the approach; Manasquan River sports some brisk current and the marina is hard up against a low railroad bridge. The bridge stays open by default and sounds a horn to warn of impending closings, which are fairly frequent for commuter trains. The dockmaster directed us to the fuel dock first, which on the incoming tide involved a very early U turn to buck the 2 knot + current and nose up to the pier, port side to. After refueling we backed down to the next T-head under power (in forward), cross-ferrying like a 37 foot kayak. Actually entering a slip would have involved some very intense springline work so we were happy to hang on the T-head all night. At 0100 a re-rig of fenders and docklines in a rain shower was necessary for the outgoing tide.

It was still showering in the morning but the weather radar indicated clearing so we got underway at 1000 hours, bucking the swells in the inlet without much issue. After one more rain shower we turned towards Absecon Inlet and Atlantic City. 9 hours of windless motoring an a cross swell could get on one's nerves, but the real stinker was diesel exhaust in the cockpit. We traded fresh air for temperature comfort and took down the dodger panels after an hour of hoping the breeze would pick up. About 1630 a breeze filled in from off the port side enough to roll out the headsail and pick up to 7.5 & 8 knots for the last two hours. We took a berth at Farley's at $2/ft + $5 for electric and splurged on a fine dinner at the Charthouse right next to the marina. In our defense, we went looking for the alleged cheap joint nearby first but there was no building to be found at its predicted location. The marina was quiet, due to early season timing or post Sandy lack of traffic.



On Thursday morning I spent some time tightening the compressor belts for the fridge. It works fine on shore power but there's no sign of life in the old engine driven system. It was 6 hour motor run to Cape May Inlet in flat water, compared to yesterday, with a light breeze on the nose. There were a few boats anchored on the east end of the Coast Guard station, the preferred spot in the harbor. I was able to find enough water to the west of the station, off the Corinthian Yacht Club to anchor securely for our first time. the barometer was still 990, but skies were clear and and it was almost 60 degrees at 1830. We beached the dinghy and had a stroll around town. Obviously still pre-season, we passed block after block of empty rental cottages.



Up at 0530 on Friday, May 10, we departed at 0615 to scoot through the Cape May canal and catch the tide up the Delaware Bay. Saw our first porpoises at the Cape May/Lewes Ferry terminal and since low tide at Brandywine Shoal Light was at 0450, we rode the incoming current, making 7 knots over ground at 2000 rpm. Passing Reedy Point at 1330, we turned into the C&D canal. Slack water at the east end of the canal was at 1345: perfect. At 1530 we dropped anchor in the basin at Chesapeake City, MD. where we met up with our friend Roger, on his way back north for the season. Beers at "The Hole in the Wall" taproom and jambalya on "Strider" made for a pleasant evening. After retiring to Juniata and sacking out, a passing thunderstorm put a stiff little squall on the basin. The shift swung us close enough to a local's pier to put out a fender and tie up. It was the reasonable course of action since the basin was full of cruisers on short scope swinging over towards us. The landowner made a point of greeting us in the morning, but just casting off and falling back on our hook was all it took to relieve the situation and take time for breakfast. Last leg Today!

Cheaspeake City to Hance's Point. Still motoring into our perennial light breeze, we got underway at 1100. Once we were below Turkey Point we turned off the wind and raised all sail, tacking back to Grove Point and across to Aberdeen just to be underway without the diesel running! We turned up the Northeast River just as the wind died down and motored up to HPYC, tying up at the pier to find out which mooring was to be ours. Distracted by visitors and dinner for several hours, Juniata Lily's keel settled into the mud to spend the night. In the morning we took our mooring and congratulated ourselves on a safe and successful delivery run, at a cruising pace.

Enjoy.

Commissioning Spring 2013

The boat had been on the hard in Connecticut for at least three years. Serious cleaning required.
Facing a long delivery run to the Chesapeake, we needed to be confident in her seaworthiness and systems.
I intended to immediately replace the old style rubber cored Groco units, but a lube and inspection let us postpone the job til this coming winter. Other items included the following:
Replace the abused stuffing box with a PSS Shaft Seal
Cockpit drain hoses needed replacement.
New batteries: 2 Group 27 in parallel for the house. 1 Group 27 for reserve/starting.
Add Battery fuses.
Running light repairs.
Rewire the Simrad Wheelpilot WP30
Rebuild the manual bilge pump.
New pickup hose for the electric bilge pump.
Epoxy repair to chipped barrier coat.
Bottom paint (2 coats of Hydrocote black).
Powerwash topsides, leak check ports & hatches.
Launder all the green and crusty lines.
Tuff Enuf bilge cleaner is good stuff.
Install C-Head portable toilet. (Lectrasan and amateur holding tank installation must go!)
Install new used 10lb propane cylinder. (Found an orphaned aluminum tank!!)
Check rig tensions.
Open fuel & water tank access plates. Drain and clean tanks.
Engine oil change, filter, raw water impeller.
