    you assume correctly, a pin in the stack under the deck allow the stack through the deck to be removed and a water tight cap put in place.... but the hole in the deck can also double as an exit for a bilge pump operated from below or on deck... if necessary, not a good situation but an essential option for emergency type situations where the deck hatches must remain closed and water must be pumped from below decks.

    ... Alfred Johnson's! he had a bilge pump built into the deck, seemed like a nice touch viewing it in the museaum, but after sailing on the open ocean and contemplating raising the hatch and trying to bail while keeping the hatch from sliding overboard this set up makes a ton of sense... so many design details are understood fully only in the operation of the craft.

    back on the water again! planning a voyage this evening over Turkey sandwiches, the plan is to go on a adventure tomorrow with the flooding tide, looking for ancient Indian middens on Plumbisland, accessible today only from the water, as the Wild Life Refuge restricts all public access to 99% of the islands interior.

    sort of a work in progress... and it depends on where I plan on sailing.

    the "navigation" is very forgiving, particularly during day light hours, any thing this boat has a chance of hitting is typically very visiable, it is simple following channels and any sand bar or rock that I can not see or see turbulence from is likely too deep to hit.

    When we went to SRR in Blue Hill we had the required gear, including a Marine Radio, map of coastal Me, compass. We also had a GPS never turned ot on or used the compass or looked at the map other than at the morning briefings when we find out where we are sailing.

    Same gear for the trip to Gloucester.

    I also have a flash light, flares, horn, foul weather gear, a sweat shirt, sleeping bag, etc. all the basics. I have sailed with water ballast so far so I usually have 20-40 gallons of drinking water in gallon jugs along, and I have a few cans of random food and a can opener just in case I need to spend the night on the boat unexpectedly... this is a enginless sail and oar boat.

    an EPIRB is on the wish list, as are a couple of Survival Suits, which I have sent out a few emails about to Craigs List sellers, no luck yet. I would also like a sextant.

    the Centennial design has proven dry under the very benign conditions in which I have sailed her. the roughest water I have had her out in was likely the trip to Gloucester with 1-2' chop, nothing close to coming over the rail even on the low side.

    here's a shot of the typical sea state on the way to Gloucester.

    A wide mix of rope... nylon, manila, stainless wire... any philosophy on which for which task? Why stainless wire instead of dacron, and so on?

    yeahhh
    so I started with hardware store Manila for most of the running rigging. and on the way to Maine for the SRR we drove through a rain storm, the lines all got wet... which they were bound to do sooner or later, and the 1/4 inch manilla line expanded to 3/8th's -1/2 inch and refused to run trough the pulleys I had on the deck and mast... so I had plenty of spare line and swapped that out for the weekend... and havnt got around to changing it since.

    I'd like to get some real 1/4 inch manila that will still run through my blocks once it relaxes, right now i've got a heavy weight sash cord which works and feels great but looks a little... low class...? I may just end up getting some synthetics from NE Rope Co we'll see.

    I am planning on getting a length of the Amsteel stuff I think it's a Dyneema for the fore stay line. and had considered it for the rigging but I was interested in keeping pretty close to the look of a 1870's working dory, hence the wire rigging, galvanized hardware, blocks and cleats and the Manilla line.

    the Manila main sheet has worked fine it's a joy to handle and is actually the same main sheet I had on the schooner dory 14 years ago.

    Thanks, hoping to get another sail in before putting her up for the winter!


    guess I could say a little about her sailing characteristics and handling. Her rudder is pretty shallow but has excellent bit when sailing, significant bend to my oak tiller handle. The boat is about perfectly ballanced, weather helm but not hard to hold the tiller, with the jib up she has a very light touch on the tiller and will likely be able to self steer, though I have yet to test this out. The boat comes about reliably and makes little leeway with her centerboard and her hull/chine working to carry her to windward, I have left the board down running as it is weighted and contributes to stability. She rows easily in benign conditions but is an issue against a strong wind or tide.

    the boat is fairly high sided and narrow on the water, bottom is 38" so she is fairly tippy at rest, like all banks dories. once you have the sails full and she is heeled over the rail is about the sheer plank from the water where she stiffens up and I have yet to put the rail under.
    the narrow waterline means this boat is quicker than might be expected for a sleep aboard short ship. Johnson recorded multiple days run over 100 miles and I imagine a run of 120-150 would be quite possible with ideal conditions.

    thanks Dave, were having fun... I spent 5 hrs aboard the other evening, eating supper, reading, catching up on some WBF videos (acorn- Arabela) and listening to the ice crunching out on the river and the rigging clacking against the mast in the evening breeze.

    short answer, yes... I built the hull to John Gardners lines taken off the original pictured above in the 1970's I stopped by the museum to measure the deck, hatches, mast/board location etc... I made alterations to the 1876 layout, including 2 acess hatches forward and aft and modifying the cargo hatch sizes and coaming heights, which I thought would make it a more useful Day Sailer.

    the only major mod I made which may affect sailing to a degree was going with an Eel style centerboard arrangement rather than the rectangular board in Johnson's craft.

    Also my mast is almost 3/4inch lighter diameter at the deck and correspondingly light aloft.

    my boat is up till now considerably lighter than Johnson sailed Centennial, he lists her displacement at 3/4 ton crossing the Atlantic my boat is about 1000lbs+- with about 400 of that in ballast.

    the tabernackle Mast set up on the original boat has proved to be excellent, once I have the sails lowered and furled on the boom, it literally takes me 1+- minute to lower the mast for trailering the half mile to my house, and only a couple minutes more tieing stuff down for Highway travel, and she sets up equally as quickly, all stays and lines remain attached, a huge advantage with such a complicated rig.

    Bit of a family resemblance.... the apple did not fall too far from the tree!

    When your water warms up will you try a capsize recovery ? She's a big 20 footer !

    Where is the 400 pound of ballast? Inside or bolted on outside ?

    yes once I get her ballast sorted out I would like to try a capsize recovery, which will likely need to be done with her rig folded.

    as ballasted currently I (215lbs) can stand on her rail and the gunnel is 3-4 inches from the water. I do plan on adding another 200 +- lbs of ballast before next season, april/may 2018

    It might be good to try a recovery with the rig up, 'cos when you go over that's how it will be !

    rig up would be ideal, the issue is most of the protected water where I would do a rollover test is shallower than the rig... but I' am also unsure whether I will be able to pull her over on my own without the mast to hang on to lever the hull over.

    In light sail and oar craft capsize in a gust of wind is common and to be expected like in the dorys and skiffs I have built in the past.

    Centennial is not our typical sail and oar boat. a capsize in Centennial would likely involve gale type conditions and dangerously steep breaking waves capable of rolling her hull and dismasting her with the force of the oncoming sea.

    you may have noticed in the short video we had +-20 mph gusts with full main sail set and did not put her rail under during the duration of the sail.
    as the boat heels further it becomes more stable and spills significant amounts of wind from the rig.

    I'd be tempted to do any testing in relatively shallow water, first to figure out how much water comes in the hatches when she is on her side. Playing with ballasted boats where there isn't enough floatation for the ballast often leads to the need for divers.

    ! yeahhhhh I have a couple locations in mind for testing, the best is just off the ramp at a small local lake, with no current and minimal wave action.

    the hatches will certainly leak with the boat over on it's side, I plan on removing her stove during the warmer months and would do the testing then as the cast iron would not be the best combination with water, especially if I'm in the salt.

    the original Centennial has 2 water tight compartments, one forward and one aft, with no access hatches on deck, I built in one bulkhead aft of the standing well with a large deck hatch as access where I stash tools and lifejackets and fuel for the stove... I have not built in the bow bulkhead... I am still considering it, VS the loss of easilly acessable stowage space for anchor, line and sails...

    theoretically the entire below decks is flotation, but like we said the hatches are likely to leak at some rate... this is the major bit of info that a roll over test could shed light on... how quickly does the capsized hull take on water.

    it is quite possible that with the ballast secured to the floor and weighted centerboard down Centennial will be unstable upside down and refuse to remain capsized.... we'll see.
