You may need more than your 6 criteria.

1^st is it a powerboat with or without accommodation (this covers water
ski boats etc), or is it a sailboat with accommodation (yacht) or
without Dinghy. (Yes I would be curious to know if my Mirror sail No 530
is still around 43 years after it was built).

The next two criteria is builder/manufacturer and their model. Some
boats were built by more than one yard (505 dinghy was built by Parker
boats, Ronda boats and others). However a Moody 41 or a Moody any thing
else will only be built by Moody

Size can be in feet or meters

The style of Rig maybe a good criterion to have (Bermudan Sloop, Cutter,
Schooner, Ketch etc)

A general description in yachts for the one off’s either under the old
Ton rating system or the more modern R.O.R.C. (Royal Ocean Racing Club)
classes

The current owner (although how you keep that up to date?)

Any Registration info

Names of vessel present and Past

That’s the absolute minimum

and contact details.


Thanks, that's very useful. A couple of Qs:

Type - is there a list of boat 'types', or would that list be so
diverse as to be useless?

Size - AM I right that boat size is always in feet?

Thanks.
