My Personal Recommendations for Portsmouth
I’m guessing by mentioning Chichester to Bournemouth you like the idea of swimming and water sports? Me too!
Theres a wakeboarding place at the top of Portsmouth, pretty much on the m27
https://www.southcoastwakepark.co.uk/cablewakeboarding 15min sessions free training and low cost wakeboard and wetsuit hire.
It’s a basic sort of place, not like liquid leisure in Horton, but at less than £30 per session it’s a great way to use up some of that teenage energy.
as far as swimming goes for little or no £ the Witterings is a great beach

be careful though, the parking has changed and may be extortionate.
if you’re travelling down towards Bournemouth, there’s Avon beach, where there’s a restaurant the noisy lobster that does beach takeaways, a bit pricey but the car parks sensibly prices and it’s still a reasonably cheap day out. You can always walk into miseries town for more sensibly priced fish and chips and have a stroll around the harbour.

Depending on your budget you may consider hiring a boat/doing a yacht charter. I’ve found these two that seem more watersports orientated

great for family days out, they leave from Port Solent marina and can visit the Isle of Wight.
i haven’t personally used them, it’s an little too costly for me just yet, but saving for a special occasion.
Port Solent at the top of Portsmouth is a great place to visit, with restaurants car meets etc.
https://portsolent.com Check out their calendar, Sundays are always good there.
if you want to visit the Isle of Wight, there’s ferry’s that leave from Portsmouth, Southampton and Lymington, which will be a lot more cost effective that the yacht charters, there’s a product for everyone.
hope this has been helpful.
