I also have to mention that vessels under 7 m with max speed of 7 knots may exhibit just an all-round white , or some irritating, pedantic, Scottish Open University lecturer formerly known as Ubergeekian, and Doctor Megaphone on BBC TV for the under fives, will.
He sounds like a fascinating chap and I hope to meet him some day. I wonder if that's the Dr Megaphone who has just had a smash hit show at the Edinburgh Science Festival? Meanwhile, you haven't got it quite right. From the document to which you linked
23 (d) (ii) A power-driven vessel of less than 7 metres in length whose maximum speed does not exceed 7 knots may in lieu of the lights prescribed in paragraph (a) of this Rule exhibit an all-round white light and shall, if practicable, also exhibit sidelights
25 (d) (i) A sailing vessel of less than 7 metres in length shall, if practicable, exhibit the lights prescribed in paragraph (a) or (b) of this Rule, but if she does not, she shall have ready at hand an electric torch or lighted lantern showing a white light which shall be exhibited in sufficient time to prevent collision.
As the fellow owner of a very small boat I'd expect you to know this. My Hunter 490 came with an all-round white at the masthead and in the first year I had my Jouster I had to cross the Clyde at the Cloch unexpectedly late and fended off a cross Modplod boat by pointing out that the torch I was shining at them was fully compliant with IRPCS.
I hope this helps. As ever, your dedication to promotion of the rules is impressive.
