A helicopter and boats were deployed to rescue the 35 migrants, including about 15 who were in the water.
A migrant has died while trying to cross the English Channel from France to the UK, the Government has said.
More than 30 people were rescued after a boat got into difficulty in the Channel overnight on Friday, the French Coastguard said.
French media reported that the migrant who died was Syrian and was crushed by other migrants while on a leaky dinghy.

A UK Government spokesman said: “We can confirm there has been a tragic incident involving a small boat on the French coast which has resulted in the loss of one life. Our thoughts are with those affected.
“This latest tragedy underlines the terrible dangers of small boat crossings, and we continue to do everything we can to prevent them.
“These criminals only care about profit, not the lives they put at risk, which is why they are cramming ever-greater numbers of people on to increasingly flimsy and dangerous boats.”
