Yes Ashley advised to use foam for the tricky bits and then the whole lot will be glassed. Might bring a few strips forward to the bow lower down near the keel where its still fairly straight.

Need to try and get a bow thruster in there too.

Thanks for that shop tip, looks great. Going to be a few weeks (if not months) before I get to that stage though.

Thanks!

I would see how you get on with the planking at the bow, and plank until the curve just gets too much (down forget you can make 1/2 cuts at the back of the strips to help the bending and THEN foam.

See. easy with the right equipment eh!! get some spare blades in . It doesn't take much to break them.

Mintanic coming on a treat, up to "planking" the rear hull curve now, and going better than expected.

Undecided on what motor to use. I have no 385s or 540/1s, only speed 400s and a 540 of unknown type. I do have a couple of 555s and Graupner ECO 600s….but the 555s are horribly sluggish on less than 12v esp as I will be using a small 35 ish mm prop, and the 600s are overkill. I expect the boat to be heavy-ish so a bit of oomph is required, so perhaps my 540 is best.

As designed the top roof will lift off complete with funnels (found some plastic 22mm plumbing pipe) and it can be turned upside down to lessen box height!

Created a Mintanic photo album if anyone was interested. Or not.

It doesn't look like much now, but I think the paint job will make it all super.

Ashley

[NoelParticipant @noel26080]

Ah right so its a wooden rendering of the plastic toy, so will it be blue/white/yellow or correct colours?

[ashley needhamParticipant @ashleyneedham69188]

OBVIOUSLY the right colours! And the funnels will all be the same shape.

All I need is a massive Titanic sticker I can stick wonky on both sides for that authentic touch.

Wow….just seen the price of the largest bow thruster at Cornwall model boats Noel…..wowsy wowsy.

A suggestion from the bench was perhaps a bilge pump could be used, to blow to [ort so as to turn the bow out to the open sea assuming you would likely be coming in clockwise…?

Or use two pumps on differential switching (spare channel?)….these could be sited in the centre of the boat with just some 15mm plumbing to get the water to the bow???Ashley

[Colin BishopModerator @colinbishop34627]

Will there be spare binoculars in the crow's nest…..?

You can get an Iceberg lettuce from Tesco which would be a green scale accessory.

Its cheaper just to bump into swans, Colin.

I had noticed the pricing on the Raboesch thrusters, the 19 to 25mm thrusters are about £40 ballpark, then you have to pay double for the 30mm one. Same motor. I know props are bigger, but doesn't make sense to me.

Doing final fiddling with frames and bits and pieces before making a start on planking the Ark.

[Ray Wood 3Participant @raywood3]

Hi Noel,

You don't need much thrust to move a ship sideways, my 20" TID tug with a 30mm prop with a 400 motor can move a 14' bulk container ship, quite amazing 😄

Regards Ray

[Tim CooperParticipant @timcooper90034]

Could you use two of the smallest thrusters? Guess that they could be separated by a few inches at the bow. Would still need only one channel or combine with the rudder.

Tim

[NoelParticipant @noel26080]

Two smaller ones still £65 though,  But based on what Ray says, something 8ft long should be OK with, say, a 25mm bow thruster which comes out at a tolerable £40 or so? That would be reassuring for the wallet as I have to invest in 4 motors, shafts and a decent speed controller too.

thanks, Noel.

I have 3 or 4 boats with 2 motors which are on separate channels, using a Robbe F14 navy. It makes them easy to turn on the spot. Some of my boats have a bow thruster which works ok but response time is a bit slow.

[NoelParticipant @noel26080]

bow thruster is probably only to help with low speed movements, I intend to have the shafts mixed with the rudder, was thinking of an Action P94 to control the outer shafts to get the effect you mention.

[ashley needhamParticipant @ashleyneedham69188]

We are thinking that the bow thruster will be needed when you are parked at the jetty and want to move off. Being able to shift the bow out a bit will be hugely beneficial, as I don't see that the turning circle will allow you to drive off and round???

I may be wrong of course, hopefully I am wrong and you will have much a much better turning circle than we think…

Hi all, just a few pics of my new Brigantine, should be ready to sail when all this marlarky is over….. hopefully!

[NoelParticipant @noel26080]

Lovely decking. Is she based on any particular vessel or just a minds eye?

[Dave MilbournParticipant @davemilbourn48782]

I'm pretty sure I've seen something like this done. It uses a standard 3-blade prop running in a plastic tube and powered by a cheapo brushed motor via a shaft set at an angle. Elegant it's not; 100% efficient it's probably not, but it's cheap, easy to make and would work OK.

[Richard BarnettParticipant @richardbarnett67129]

Not really Noel, like most of my stuff a bit off the cuff with cues from the clipper ships of the late 1800s. Going to be using two sail winches, one for the square sails and one for the big gaff + the fore sails. Should be really controllable and interesting to sail.

[Eddie LancasterParticipant @eddielancaster]

Hi.Richard, I also like your deck detail, I have a schooner at home waiting for me to get back to, the first job will be the deck planking, I hope I can make as good a job of it as you, what size is your boat? and the width of your planks?

Regads.

Eddie.

[NoelParticipant @noel26080]

Dave, on same subject I was thinking similar,like this:

Which might be easier to install.

[Colin BishopModerator @colinbishop34627]

Could be easier to install but I think you woud find the the sharp bends would severely affect the waterflow.

Car windscreen washer pumps have been used as some of these are bi directional so the the water can either be delivered to the front or rear wipers. I think this would require a hole in the bottom of the hull to supply water.

Colin.

[ashley needhamParticipant @ashleyneedham69188]

DM like your sketch, but not sure Neol has the width available at the bow?

Noel. I think that two bilge pumps in the centre section leading to outlets at the front would be effective. You only need to bash some 50mm holes n the base and sit the pumps above them. The pumps are rated for about 4m of lift so a few feet to th3 bow would be nothing. 24 quid for a pair…

Ashley

[Dave MilbournParticipant @davemilbourn48782]

I doubt that a car windscreen washer pump would have the power to push this monster around, Admiral. A couple of the Rule 12v bilge pumps that Ashley uses would probably do the job but that would push the cost back up.

Dave M

[ashley needhamParticipant @ashleyneedham69188]

That’s what I meant DM, the bilge pumps. Non-rule ones are 12£ a pop. Ok so far on my two operational craft.
