Steve,
a Hartley 16, trailer sailer? Back in around 1970 my eldest brother handed me a design catalogue; “Boatbuilding with Hartley” (6th edition, 1967). Luckily, I have kept it. It is divided about 50-50 between plywood and ferrocement designs. The 16TS is there, for sure. Unfortunately there is no direct profile view with sail plan, but I am sure she would be easy to fit with a junkrig, some 12 – 17sqm, depending on displacement and ballast. If you are to trail it, I guess you want some quick way of lowering the mast, but it should not be too difficult to sort out. Small is beautiful, in this respect.
Cheers, Arne
PS: Now I found the sailplan and details: Disp.= 800lbs and SA=180sqft; that is 363kg and 16.7m2 in my money. The junkrig mast would fit through the deck, right in front of the cabin. Hopefully that will not collide with the interior. Remember, you can also offset the unstayed mast to one side, a bit, if necessary.
Thank you Arne. I have just been reading your introductory material on this site. One thing I was a bit worried about with the TS16 is that with a wide aft and sharp bow they do need to be watched in heavy weather as they are not well balasted and with the beamy aft they can tend to steer downward into waves as your quote from Bolger indicates. Two things I was planning to do to try to make mine more of a cruiser and less of a racer was to increase the balast somewhat by replacing the steel plate centreboard with a heavier one, and to re-rig her with something that is able to respond quickly to rapid changes in wind conditions, which is a feature of our local gulf water area in South Australia. It looks like the JR is the perfect solution to at least the rig question.
I figured the position of the mast to be as you indicate, just in front of the cabin. that area is not difficult to strengthen with some timberwork under the foredeck, and the mast would not intrude into living space, just into some storage space, which is a compromise I am happy to make.
I was thinking of maybe a tabernacle for the mast, but I don't really want the complexity of cutting a slot in the foredeck to allow for the mast base to swing through.
What do you think of a tabernacle with high cheeks? The tabernacle suport can still be mounted through the deck, but the mast base itself would just sit at deck level within the Tabernacle. A light aluminium tapered flagpole would offset the weight of the tabernacle and woodwork below deck so the balance would not be shifted too far forward.
The other alternative is to simply step the mast through the deck, which would be easier than a tabernacle, but I think it might be harder to mount and dismount the mast.
Your thoughts?
