in any group, everyone should have similar boats.
i was selling my 9.5' Rush and some guy with a 16' sea-kayak wanted to buy it for his wife.
I refused as she'd never be able to keep uip with him and both would be angry. he for having to wait, she for being left behind.
When we paddle in a group, the longer boats are ALWAYS far ahead while the shorter boats are far behind.
It does no good for everyone to promise to keep together as that never happens.
one time Harry was in his 14' loon, I in my 12' Dirago and Gail in my slow Scrambler.
Of course Harry was gaone but when I looked around, so was Gail. I back[-tracked to find that she had overturned and could not do a wet-entry and was holding ontothe kayak while trying to push it across the lake looking for us.
I managed to help her reentry but it taught me a lesson and no one else ever learned. Watch out for each other.
