Half models

[flaming]

Does anyone know of a half model builder that would take a commission?

This sort of thing but for a specific boat.

Google is not helping...

Hedley half hull models - Hedley Half Models made a stunning job of one for a friend.

Just the thing, thanks!

Derek Moreland at Yachting Sports in Hamble Point Marina used to build those but I can't say I know whether he does anything like that now

Or if you would like a whole hull model, Peter Kunst builds these - he only seems to have a Facebook page though.

It'll be an interesting exercise if the boat's lines aren't published. My hull's manufacturer refuses to release them.
Lofting the lines would require the boat out of the water and quite a lot of skilled time I imagine. Photogrammetry is possible but a rather esoteric skill.
Anyone had experience in this?

A laser scan is quicker and cheaper, then can be scaled for a CNC milling machine

Bit of thread drift - there is a fantastic display of whole and half models at the New York Yacht Club. Over this side of the pond, the Model Room at the Royal Thames Yacht Club is a treasure trove of half models, depicting many of the most interesting yacht designs over the past couple of hundred years right through to today. Foiling cats and other modern keel appendages do represent a challenge for half model displays.

You will probably find that David Spy has made a couple of the displays in the NYYC.

Not boats, but same principle....

What type / make of boat do you have (apart from being slow, which I am sure she is not)?

I have been involved in taking lines off a few boats in the past, and it is not that difficult really, especially if you are not looking for extreme accuracy - you don't need many sections in order to compile a rough lines plans that you could build a model with.

The manufacturer of your hull needs to join the real world. Lift your yacht and a within a very short period of time, hours, a very accurate model of your hull could be made with a 3D printer, full size if you want, and then use it as a mould.

You just need a camera, some software (maybe free, see the link) and then feed to a 3D printer.

There have been a number of threads, I think in the PBO section, on 3D printing and some of those contributing to the thread would know how to develop the programme for the printers. Some public libraries in Sydney have 3D printers (as they do photocopiers) and offer support for the software - I imagine you might find the same in the UK. Commercial office support businesses offer 3D printing services in the same way they will copy plans (or charts).

The art of the 'half model' maker has been brought into the 21st Century (and I suspect might be cheaper than crafting by hand (painting is a different issue demanding different skills).

Surveying companies have survey lasers that sit in the middle of a site, or room, a kitchen, for example, & it rotates & scans all the dimensions. A scan of the hull of a boat could be completed easily, by such equipment. You just need to enquire to a local survey firm that does that work. They sub contract to architects to provide drawings of existing layouts.The data can then be down loaded to CAD
