Re: New design build Ally 40 footer

With the sail Drive I can sit the big fuel tank over the Keel will be a mission The keel will we have to pressure tested with a manometer first and then fuel tank pressure tested by the same method 2/8 feet of head water pressure and that means pumping the tank full of air into the clear plastic loop so that the Water on one side of the loop Rise is 8 feet above the water on the other side There is no good text testing a tank with soapy water you may think it is tight but if you leave them in the tank overnight and the water in the clear hose the water should stay at a given level in the hose Of course I have the water tanks in the wrong place I must move them forward a little because classification societies do not allow one tank against another* they must be separated by a coffer Dam Which is ok because this becomes a bilge pump station
but I think it is 700 litres of fuel it is all good fun the idea is to fill it up with red diesel from a farm)at tank placing after settle engine detail

Re: New design build Ally 40 footer

Hello, Since it's been mentioned that draft is a concern, I'm wondering if you've considered using a swing keel, possibly hydraulic which could be locked in the down position in heavy weather. Thoughts , anyone ? Thanks in advance, Pappy

Re: New design build Ally 40 footer

Or the solution Ovni took with the ballast low in the hull and a centerboard that is light enough to raise manually.

Yes I know that both took that check with the Swinging Rudder 2
But really the draught is ok as it is I like my Bala slow down I want this to be the ultimate I mean I know everybody says ultimate but put it this way I want it to be a very very good boat in very extreme conditions such as the conditions you off and get off the coast of New Zealand when returning from the Pacific Islands or if you want to circumnavigate the Ovni is a very expensive boat what it is very popular I can see that but I don't like the way it slammed to Windward and it back any small seas it is very noisy
But when I was commercially building I would like to be a fraction of successful as they were in marketing they are doing very well just need a bit of competition

FWIW, it is possible to edit a post for a while after it has been posted. You click on the edit button that appears at the bottom of the post, and a writing box appears. Seek out and change the typo. Click on "save". I confess, I use it a lot!

Re: New design build Ally 40 footer

Stuart,

Just a thought, but if you can place the water tanks under the cabin sole, then a lot of under the settee's area would become available for stowage.

Good on the shaft drive. Now, how about a Beta (Kubota) diesel , with parts availability from tractor supplies, instead of the Yanmar, with it's highly expensive parts structure?

Ann

Re: New design build Ally 40 footer

I've gotta say that I'm definitely a fan of flush foredecks, such as in this design. They make for a handy spot to put a hard dinghy. Not to mention being much easier to work on than climbing around on top of coach houses. Plus, having forward facing windows on the coach house, as in this design, makes for great visibility. Both at anchor, & when underway. So that one needn't always go on deck to do a cursory check of things, or for some types of navigating. Plus it makes it simple to lead the chain aft to a more central location, so as to get it out of the bow.

Such designs also have the perk of allowing some of the tankage to be put underneath of the cabin sole, in the part of the boat underneath of that aft coach house. And to be able to do so without giving up proper headroom inside. Quite the opposite really, as when done correctly, they raise one's height of eye up enough so that it's easy to see 360 degrees while standing inside of the cabin. So some of the older designs definitely had things right in this regard.

For fresh water tanks, I'm a fan of placing them underneath of a pair of pilot berths in boats of this size. You can fit ones which are 80gal+/- into a reasonable amount of space on each side. And in addition to giving you lots of water tankage capacity, they contribute greatly to a boat's stability. To the point where one can make the keel a bit shallower draft, or lighter, while still maintaining good righting moment. And extra Rm is quite handy in a boat designed to be a powerful sail carrier, as you stated in one of the initial posts on her in this thread.

Though when it comes to adding extra stability, I'm a fan of delta bulbs on fin keels. They put a lot of weight down low, while giving the boat a good flat surface on which to dry out. Are pretty hydrodynamically efficient when done right, & are fairly easy to construct, while leaving room to use the fin as a fuel tank.

I look forward to seeing how this boat evolves, & what she'll wind up looking like when she's "done". And it's always fun to watch a CNC laser do it's thing when it's plate cutting time. They're fun toys!


Edit: On the layout. Might it be possible to convert one of the aft cabins into a room with a dedicated work bench, including a vise. Along with built in shelves to provide for storage underneath. With stowed items to be organized in plastic bins (with lids), & milk crates, etc. Along with an oilskins locker with a built in dryer (from the engine).

Plus some dedicated storage for sails, spare running rigging, & an inflatible plus it's OB. I should think that with some proper racks, shelves, & bins, such a room would be invaluable in a cruiser. As other than in a charter boat, a 3rd stateroom is a bit unnecessary, & the space can be put to better use.
And before you ask, yes, I'm jealous of Skip Novak's setup in his boat Pelagic
