We found Happy and Grumpy when looking for a snorkel operator with a boat suitable for someone with significant erious back and knee issues, making a functional ladder/stair that goes well into the water essential. There were three in our party, one reasonably fit and active, one that has very limited mobility (limited walking with 2 canes) due to two worn out knees and a bad back and one that is senior with one knee replaced and the other on its way. All 3 of us are comfortable with the ocean and decent swimmers. They were prompt and helpful to pre-organize our trips and on our first day out quickly had everyone at ease. The ladder on the boat is extremely solid with a angle out from the boat (giving it more of a stair feel rather than straight up and down). While you certainly must be able to lift/pull yourself out of the water this was only slightly harder than a steep flight of stairs. The step over the edge of the boat was the toughest part if you don't have a good working knee. Jolene quickly sized up our ability and all 3 trips were excellent and well suited for us.
I hope to be back to Belize in the future and we won't think of using anyone else for our trips out to the reef.
