Looking good Larry.

I also find her a fair weather only boat any strong winds are too much. Hope nothing too serious occured.

Hi Larry , great photo's. Will I ever get mine done?

A chap at Doncaster gave my a good demo on plank on frame so I may build a second hull using his techniques it was simple and straight forward.I think he was from the Kleytonwest club.

Nice to meet Gareth and his wife from the Gool MBC Had a pleasent chat on yachties in clubs .It was a helpfull day but only got some batteries.

Hi Larry,

she looks nice on the water, looks a nice bit of water too.

If you have to add weight its best added at the keel. How are you controlling the sheeting, arm or winch servo? An arm can get the sheets out quicker in a gust, but can be more easily over powered when sheeting in.

[LARRY WHETTONParticipant @larrywhetton68737]

Thank you Kim,

sail are controled by a simple arm ,

as shown in photos on forum, will be adding extra weight to keel,

how did your sail boat go..?…. cheers Larry.

Hi All,

After a break of around 2 years, I finally got round to rebuilding the hull of my Jenny – I saved the keel of my damaged hull, and now have a new hull, planked, sanded and stockinged I have used varnish instead of fibreglass resin this time, as the fibrreglass was very tough to sand down afterwards, I'm hoping the varnish will be easier. I'm just waiting for the varnish to dry right now, before I give her another sanding, will then apply some primer, before fitting the keel.

Next job is sanding down to size the dowels for mast and booms, and making the sails – I must dig out the magazine with the build articles.

I'll post again when I have more progress, and try to remember to take some photos.

Cheers

Ricky

Hi all,

My Jenny build is coming along nicely, I have fitted the keel to the hull, and given it its first coat of enamel paint. I have been sail making for the last couple of days, and have washed and dried the sails. sealed the edges with 50/50 dope/thinners and started putting the eyelets in.

Just a quick couple of questions, the sailmaking article refers to "fabric backed sticky tape",for reinforcing the edges of the sail where it is laced onto the mast and boom, is this Duct tape, or something else? also, the reference to thin cord in that article, I bought some braided seine line, from boyes, this is a braided nylon, around 0.9mm thick. This should be good for lacing the sails to the mast and booms, but I am not sure if it will be OK for the standing rigging, anyone have any ideas?

I have collected several dozen coffee stirrers from various coffee shops for the deck planking, I am thinking of staining them mahogany colour before planking the deck, should look nice. I'm just debating whether to mark the edges with black marker pen, or glue black paper to the edges so that the planks stand out more.

Cheers

Ricky

Carl,

Although I have one of these little yachts, I am sorry I am unable to help with any of your questions. Regarding the sail making, for my yacht, I had he sails made by Housemartin Sails, as did Douglas McGhee (the designer). I also bought the braided nylon line and bowsies from this supplier. I guess the line, although the smallest size, is a little over scale. The smallest plastic bowsies were used on my model, where wood would have been more in keeping with a yacht of this period.

For the deck, a sheet of ply was lined with a black ball point pen. Your idea of using individual planks would make into a more accurate model. If using coffee stirrers, why not collect a few extra ones and use some as samples. As for the little cabin, my first one was made in walnut which bent out of shape (probably not seasoned) and a replacement mahogany planked one was constructed.

Sorry I can't be of any more help.

Looking forward to seeing the continuation of your model.

Hi Guys

Has anyone thought of enlarging 'Jenny' upto 36'' or even 50'' and if so dose it work ?

Just sitting here bored, as its to hot to work Reg

[Tony HadleyParticipant @tonyhadley]

Reg,

The designer, Douglas McGhee built a second model at a larger scale, rigged as a schooner. If my memory serves me right, he sold both models (something he regretted), and I am unsure as to how this second model looked or performed on the water.

A model along these vintage lines at a larger scale (1:10) and size (35" long) is the Bluebottle design – MM293 in the myhobbystore shop. Although this is a much more difficult model to build, some of the construction methods used with Jenny could be worth considering.

Enlarging a sailboat model rarely throws up problems of sailing quality. Its when you shrink them that problems arise.

The problems that can arise are in the area of structural strength – more or beefier frames, rigging needs to be stronger, control systems need more authority. If it comes to that, you might need to be stronger. Not only will it be heavier, the sails might make for rather a handful when carrying it in a breeze.

[Tony HadleyParticipant @tonyhadley]

Whilst stored in the old shed (which leaked like sieve), this model had suffered during storage. Now I have a new dry shed, Jenny has been undergoing some much needed tlc. Hope to have her back on the water next week.

Took this photograph which shows the lovely shape of the small yacht's hull.

Hi. I started a "Jenny" around ten years ago, following the lead of a friend in Northampton. The intervening time has been taken up with model aircraft and secretary-ing for a Club.

I have now gone back to boats, which I should have done years ago, The Jenny is complete as far as hull, keel, ballast, stocking work. The decks are cut out from sheet spruce 1/16" thick and I made a jig so that I could be sure the decks were well in contact with the hull when gluing, using balsa "props".

I now have to complete the model. I have enjoyed reading this thread, and will take on board some of the suggestions. I aim to get all the sheet work within the hull, rather than an external arm. Finishing the servo installation is the next job.

I will post pictures as I go.

[Tony HadleyParticipant @tonyhadley]

Spotted this new kit, Lili, from German manufacturer Aero-naut. Looks very similar to Jenny, with similar gaff rig and model dimensions. Looks a really neat little yacht. Not sure of the availability in the UK.

I no longer have my little scratch built yacht Jenny, sold earlier in the year.

Hi Guys

,I built two Jenny's in 1988,. one`use to sail very well but the other its a bit of a rat bag.

I think they were base on a 1920's young boys toy. I have not sailed them for some years but I am re rigging one at the moment hoping to have sail again this down under summer that's if I pick the right one!!!.

Cheers ,

Hutch.,

[hutchParticipant @hutch73959]

Hi Guys,

I have re rigged both models of Jenny and found some servos for them,plus a receiver for each I have a 2.4 ghz system.
The hulls have cracks along the join between the keel and the hull {well they are 30years old next year} I have used putty to fill them ,then will repaint, I hope to have them in the water next week.

.Our group the Adelaide Model Shipwrights meet every Tuesday morning at the Bonython Park round pond just by Port Road,Thebarton, Adelaide South Australia.

Cheers,

Hutch

I've been inspired by the lovely lines of Jenny and have consequently purchased the plans. I'm considering making some alterations and would be interested to hear any comments.

1. I intend to sheath the hull in glass and epoxy rather than the nylon stocking suggested,
2. If possible I'll mount the sail arm servo inside the hull (it's pretty tight for space but I'm hoping I can figure out a way.)
3. Filling the keel space with lead shot doesn't seem a great way to ballast the boat. The lead nearest to the hull will hardly be providing any righting moment when she's heeled. I'm considering two options.

• retain the underwater profile of the boat but add on a cast lead extension to the bottom, taking care to retain the fore and aft weight distribution;
• scrap the keel and replace it with an aluminium fin and lead bulb held in a keel box formed by plywood doublers inside the boat. Of course this will take up valuable space within the hull.

I'd appreciate any thoughts. Or am I overcomplicating things and would be better to just follow the plan.

I might just pick up with Jenny again. Currently refurbishing an IOM Wotsit 15 years old, and doing a bit of wood turning as well as gardening and and and.

I have the arm in place and the cabin coaming made. I need to route the sheets and try it all out before attaching the deck. I will probably replace the servos with Savox ones, which have worked very well in my IOM 3-dogs (20 years old) and a semi scale 8 metre yacht (1 metre L-WL), of which we have around 20 at the Club. We also have a fleet of DF65s, and I am (fairly) sure they won't mind if I tag along at the back with Jenny.

I ballasted Jenny with cast lead sheets to about half way up the keel and epoxied in place, when the keel was still open down one side. When I made the hull I had no idea what to do, but it seems to float well and should be stiff enough. The keel is bolted on with SS bolts, and the join is filleted with P38 filler. I used the nylon stocking approach, and covered the hull and keel separately, prior to bolting. I have a brass ready-made rudder and tube, which I intend to clad both sides with thin ply. A good size rudder will help with tacks. Last thing, if you use Spektrum, consider the fairly new AR410. I use them and have had no problems in the sea water we sail on. No aerial, so they can be enclosed in a balloon.
