Affordable seaworthy cruiser

I like it

 

I should have posted it under "Affordable passagemaker" thread.

 

Was appropriate on both threads,

thanks for sharing.

 

I think it is a Russian Espionage vessel. Notice antenna in superstructure.

 

Add a few cans of foam for good measure and make it an unsinkable passage-maker.

 

Greetings,

Back at it again,

Wheelhouse, fuel, and primary berths are right at pitch axis. The wheel house and berth area are 4.5' in height plenty for sitting. If there ever was a good reason for steps at door entry this would be it. Upon entry there is a full 12"x24" landing step with rail to the right this allows you to have some room to monuover into seat or helm. Exit is also made easier by steping down to open handle and then step out. There would be a flipup hatch next to railing to drop down at night to keep dark as well as additional water seal.

Five water tight bulkheads with dedicated engine room in one. Was on ebay and found new 28HP flat head cat diesels for $2,800.00 probably made by kubota or mitsubishi, would sound good to say its CAT powered. Preferred engine would be the Duetz air-oil cooled if smaller ones are available. Engine, fuel, and batteries are all brought very close to mid section. The five fuel tanks exit in engine room. Enough room for all filtering, tools, and maintence. Light guage aluminum can be used to line engine room for extra fire protection.

The wheelhouse has 6.33' x 2.0' chart table right in front of helmsman with space below for navigation equipment. If any of you have ever sat in a chevy van conversion seat you know how comfortable they are. Tough fabric or naugahide version, with built in seat belt, armrests, many adjustable positions and cheap.

One new twist if you look at foreward area is the developed forefoot, another Bolger idea but done differently since its included with the full keel. Boat is built with bottom up on frames, four layers of 3/4" AC nine ply on sale out the door at Home Depot for $25.00 per sheet. The bottom profile is more upswept forward, after the stacked keel is built the mini frames are added with plywood sheathing then filled with foam and whole bottom is glassed. Turn over and assemble bulkheads and frames. Sides and deck: 2x4 laid on edge and cut in half making 11/16" x 3.5" first layer running fore-aft with two more layers of 3/8" ply for total thickness with glass of about 1.5"

You guys can laugh about floatation but this is what you get constructing this way along with sound deading, insulation, warm looks, strength, etc... Even if on occasion an atoll is hit it should be just glancing the main concerns would be fire and lightning which if properly prepared for, remedies are already in place.

This way you have a V shape forward which with other benefits previously mentioned will give superb ride. From other boats with flat bottoms or low deadrise at mid section slamming is not a problem, there is only concern at the fore where the boat first encounters the water.

Small, easy to manage sails are get home measure as well as for steadying roll. Total of 550 gallons fuel and 210 gallons water. Aft of engine room additional space for berths, workroom, or maybe small clothes washer. For short excursions enough room to sleep six if master takes bow area, four can do extended cruising, and ideal for two indefinetly.

Forgot on deck their is aluminum or wooden slat folding seats.

 

Religion and boating

A tourist went to Israel and to lake Genessaret. By the shore he saw local "cruise" boats. Down he went and asked for a trip. The price was something he felt was a ripof..
-WHAT? With that price I can buy a boat like that back home!
-Yes sir.. but this is the lake where Jesus walked on water.
-No wonder... He didn't like your prices either

 

How do you access the pilot house? The door shown at the aft end of the house appears to connect to stairs which lead below. It appears from this sketch that you would have to open the door, and then jump over the hole in the floor to enter the pilot house.

Nevermind, I just re-read your description, it appears that I interpreted your sketch correctly. I can't imagine a less safe configuration than what you have drawn.

 

Goodwilltoall , if the box keel was about 2' wide then a center board would fit into the seats . I still think the engine should go in the keel and the pilot house over that , so you get a lower house with standing head room

F

 

The plan is obviously for a crew 5' tall while sleeping in berth and 7' tall standing in the wheelhouse. So there's no need for jumping..

 

Standing room is where its necessary, the galley and shower. For safety at sea and size you work with, not everything desired is possible.

Sail design is awaiting completion with probable inclusion of developed-Vee.

Off topic question but would like to know if a steel boat such as this design would need insulation in the engine room or storage areas?

Peace.

Another view:

 

Please, lower the house for safety at sea .

 

All de fuel on one side mon, she make de boat heel over, you know? Even I, an ignorant peasant boat man know that.
Full tanks heel one way (a lot), empty tanks heel the other way (a lot). Fuel tankage should be pretty well split p & s, so you can easily trim the vessel by drawing on one tank or the other.
Again I repeat to the point of absurdity, a $20 scale 'flotational model', using paraffin (scale weight of fuel) melted into place in your proposed tank locations and pennies for scale weight in the water tanks will make it obvious what the problem is. Trying to do this on paper at your skill level is not working as you make beginner's mistakes.
3/4"=1' scale is 1/16 full size and linear ratio is 16, which is very easy to square, extract cube roots from and to cube. 16x16x16= 4,096 so if your model weights one pound the vessel weighs 4,096 pounds. A Lincoln penny scales very close to 25 pounds in 3/4" scale so it's very easy to trim the model and work out every thing in cardboard and balsa before you launch the real thing and it's down by the stern and heeling 20 degrees.

 

Bataan if you do the math he has tanks on both side, no storage.

Goodwill if you are trying to save money how come your scantlings are so heavy?

 

In the drawing the math shows 260 gallons fuel on stbd side and 105 gallons water on port. Seems out of trim and not quite right to a seaman's eye.
