Boat Trip for somone with mobility issues

Could anyone suggest a boat tour on St Lucia that would be suitable for someone with slight mobility issues please?

We have visited St. Lucia before and went on Cosol's tour which was excellent, however part of the trip involved climbing down a ladder from the quayside into a water taxi which caused problems for mum who has a dodgy knee! Normal boarding of boats is not a problem, neither is climbing up a ladder but the poor love really struggled with getting down onto the kerbside and then down onto the ladder.

I'd be really grateful for any suggestions, thanks.

You could consider a catamaran or other ship tour right from the pier. You'd load and unload right from the pier, no large step-down or step-up.to contend with and gorgeous coastal views... Check out Mystic Man, SeaSpray Cruises, Carnival Cruises, Bateau Mygo, etc...

Happy sails....

Thank you so much. The Mystic Man tours look perfect and the reviews for them look really good. We're sorted!
