Hi teemie,
Firstly sorry for your recent loss.
There are two main ways of selling boats:
1) Privately, have a look at Appolloduck website to get an idea of adverts
2) Through a broker, who will charge an agreed commission on the completion of the sale.
There are pros and cons for each method of selling.
If you have a look at a few brokers websites you will get an idea of the information provided. The type of info typically provided
1) How long is the boat in feet? (if widebeam how wide, ie: what is the beam?)
2) What year was it made and who was it made by? (Eg: Liverpool boats, Colecraft, Reeves etc)
3) What engine does the boat have? How many hours on the clock?
4) When does the Boat Safety Certificate expire (MOT for boats that lasts for 4 years)
5) Recent maintenance.
6) What type of heating system/water/electric systems on boat.
You can try the following sites to get an idea of the info presented by brokers
