Thoughts on two part dinghy

[Wansworth]

Latest thinking(mine) is a a 7 foot dinghy made in two parts.The stern section 5 ft long with athwart for rowing stiffening the forward thwart.This section could be used on its own in emergencies.The bow section about 3 ft long would be basically a sealed box with access for carrying light stuff.There would be room to stow the bow into the stern and the whole would stow over the forehatch,which could be left open.Basic flat bottom skiffconstruction in 9/6mm ply.

Interesting!

Two parts - one 3 ft one 5 ft make a 7ft dinghy.

I should have concentrated more in my maths classes!

dinghy issues..

i guess i'd need to know how much space you have on the foredeck for dinghy storage. if a 5 footer would fit but a 7 footer would not, then you don't have much choice btu to go with the 2 piece. as for me, on our 33 ft boat we carry a 7 ft pram (chesapeake light craft eastport pram) which is all in one piece. it hangs off stern stanchions in harbor for easy boarding and theft prevention. and swings onto the foredeck easily for traveling at sea. our neighbor built himself a 2 part dinghy and found it to be quite a pain to dissemble/reassemble each time he wanted a dinghy. of course he had a 25 ft cape dory so had little choice as his foredeck length limited the space for storage...

The boat is a 27 footer so to leave room to work the anchour etc a five footer leaves enough space and the three foot bit(making 8 foot!!!!!) gives a dinghy that can be rowed properly in semi shelterd waters.Having had an inflatable I think the time for assembly etc would be quicker that inflating and you would have a decent rowing boat

Wot do you expect I had a comprehensive education!!!!

an idea which has been looked at previously. PBO had an article a few years ago with line drawings. It might be worth a look in their archive section.

This might be of interest to give you some ideas:

This might be of interest too. I have just built an Eastport pram - the fixed version, and it is a grand little dinghy. The UK agent is Fyne Boat Kits, but I don't think they are listing the nesting version yet.

Wooden Boat has the Nutshell Pram, a 7ft6in stich and glue tender. Rows and sails quite well. (also comes in 9ft odd) Decide where your join is going to be and fit two bulkheads separated by some thin card while you make the boat in one piece. The bulkheads should be well above the expected water line and come up to the gunnels from, say, seat level. When finished, use a thin saw to cut between the bulkheads. If you fit some locating pins, then a few SS overcentre clamps on the outside would be a quick method of assembly. Two at the gunnel and two at the water line, protected by wooden fairings.
Nice winter project.

Thanks to all,some interesting ideas.

Mogy,
This guy seems to have designed and built a few nesting dinghies and offers a plans service. http://www.wavedancer-yachtdesign.com/html/Piccolo.html

I have had a bit of a dig and cannot find any reference to the design of mine but there must be plans somewhere. I will PM the original owner though he may I suspect be pretty busy so don't hold your breath on that one. It is unusual in being a stem and not a pram design. Did Iain Oughtred (sp?) do any perhaps?

I believe that Snowleopard of these parts has just built a dinghy using epoxy covered foam sheeting, a method that I favour over plywood.

Another approach would be to have a wander around where your boat is and procure some dinghy and literally saw it in half and add two half bulkheads? At least you will have some idea of the finished weight then! And could be v inexpensive.

I belive that J Slocum cut a dory in half-so would be in good company!

I saw a yacht recently with a Nestaway dinghy on its foredeck, and to be honest it was still a BIG lump. On your 27ft boat, I think it might be too big. There's a lot to be said for inflatables.

 

[Poignard]

I have a 28' boat with a narrow beam and I think the only way I could have a rigid dinghy is if I tow it.

 

[PuffTheMagicDragon]

My Centaur is 27 feet long and carries the dinghy on davits over the stern. Murphy is 202cms long (approx 6' 7") rows beautifully and moves at a fair pace with the Yamaha 2 at half throttle.

Been there, done that with a 9' nesting thing from BandByachtdesigns.com the designers of the Two Paw mentioned already. I modified mine to make it a canoe stern, so it fit on the foredeck better.

A few issues became apparent on my 26' yacht. Lifting the dinghy assembly up on my shoulder to set or retrieve the anchor. The 15-20kg weight of lifting those 2 parts onto my shoulder as I set the anchor, and lastly "what would I do if I needed the inner forestay?" from the bollard under the dinghy parts.

I've gone on to build folding dinghies now, with the www.woodenwidget.com Origami model and one of the www.seahopperfoldingboats.co.uk Am soon to test them for practicalities in the summer holidays.

If you are considering folding dinghies, try the flapdoodle (google it). We built a 6ft scaled version last winter. It rows beautifully, stows in a locker (but our lockers are cavernous), but is a bit heavier than we'd like. Mark II is on it's way!

Yes a bit tight on the foredeck.Iam thinking to fit the dinghy up against the mast so there will be more space for anchour work and the forehatch can be left open under the dinghy as required
