Kids-Time travel-Cave with boat?

I'm trying to find a children's adventure book about kids that find a boat in a cave and it takes them to other time/places.
-Could be 2-3 kids, siblings + friend?
-Could be a series
-Kids were on a holiday, or just moved to a new town - England, Scotland or New England
-Don't remember when the book was published but the setting for the story felt older (mid 1900's)?
-First listened to this book 10+ years ago on tape or CD

The Wind Eye?

>1 tea_and_read: Hi, new here; exploring the site. The book you've asked, about sounds like one from the series "The Time Warp Trio". 3 boys, time travel, history. Fun books that my kids read 15-20 years ago.

Touchstone: Time Warp Trio

Hi! Thanks for the suggestions but they are not the ones.

I'm 70% sure the author is female.

I really appreciate the help! This quest has been driving my crazy for a while.

Maybe The River at Green Knowe?

Magician's House series?

It's not quite right but maybe Voyage of the Basset series? There are several sequels by different authors.
