Founded in 1949, the Skegness Sea Adventure Society is one of the UK’s oldest diving clubs. Our dive program consists of local dives plus a annual trip to an Mediterranean. Occasionally, we even go further afield, while our regular meetings also feature guest speakers.

We have local dives every month, and we have used all of the dive charter boats from Boston up to Mablethorpe. In recent years, our members have taken part in trips to a Caribbean Sea, Spain, South Africa and Malta, and we’re always looking for new members and new ideas.

1 Our dive program... 2 local dives 3 a annual... an Mediterranean ?

4 further afield, while our also 5 used all... 6 a Caribbean Sea 7  members and

Explanation:

1 Dive is an adjective to program so the participle diving is better.

2 Local (diving) excursions is more accurate.

3 The correct form of the article is an annual  and  a Mediterranean one refers to one of the local 'dives'.

4 Skip the afield replace while for and and also refers to something else that is not mentioned.

5 Used all wants to impress but it is better to note that the diving association works with charter boats.

6 The Caribbean Sea because there is only one.

7 Replace and for with.

But I´m sure there are more mistakes in this text...
