Re: Dinghy and Davits

These tubes came from FP and are the original wall thickness. A heavier tube would be nice but the inside diameter would have to be the same for the davit ends to work.

Re: Dinghy and Davits

Seems like a lot of leverage. I would want to make sure the inboard attachment was beefed up (especially on a charter boat).

Re: Dinghy and Davits

Probably have to get from FP as being 80mm OD it is not a standard size tube that I can find anywhere

Re: Dinghy and Davits

Nice job Mark. I don't see any drain - do you have one? Is the hull bottom out of the water enough to put a self-bailer in? That would be nice.

Re: Dinghy and Davits

very nice.

When you have 4 adults, does everyone sit on the centerline facing outboard?

What do you figure the load capacity to be?

Re: Catamaran Dinghy

Great dingy. Congratulations. Have been an admirer of the concept of a small cat dingy for a long time.

First saw the concept with a M&M design dingy built for a M&M 50ft cruising cat built in NZ some 12 years ago by an American couple that are now based in Tasmania.

There are quite a few home builders with there own designs but the Spirited Kit/Plans available in Australia in Foam/balsa/ply are similar in concept/weight to Cotemar's dingy.

Using such plans one could resin infuse flat sheets of foam oneself or have someone do it to be cut into parts for assembly if not in Aus or if in Aus buy the kits for assembly.

Spirited Designs - Home of the Spirited 380 by Craig Schionning

Quite a few building Schonnings catamarans have built cat dingys as a learning curve to building the larger vessel.

Not having tested a spirited design dingy myself but looks suggest similarities in operation. There are 3 x 4.2's that have been built in Hervey Bay in an article as day boats according to latest Australian Multihull world.

Anyone in or travelling through Hervey Bay In Aus that can check them out?? --- 44C perhaps !!

Re: Dinghy and Davits

I saw the article in Multihull world and thought the concept looked good. Passing through Hervey Bay in about 3 weeks so I may have a look

Re: Catamaran Dinghy

Damn near the perfect dinghy, well done sir.

As others have said some drawings would be great, I wonder if an "Open Source Catamaran Dinghy" thread would work

Kipper had made one which worked well. You may want to PM (Private Message) him.

Re: Dinghy and Davits

That catamaran dinghy is a thing of beauty. Did you build it? Lots of molded surfaces. Fantastically light no doubt due to design feature that blends bulkheads with logical curvature break points maybe eliminating/minimizing need for cores?
