Re: Walker Bay RID 310
It should be fine for your intended use - as a side benefit you can get the optional sail package and turn your boys loose on it to learn to sail. It's no racing dinghy, but you can't capsize it either.
Use the main halyard to hoist it up over the rails, then swing it to the deck while letting out the halyard slowly
Depending on the E 32's stern you can pull the dinghy's stern up out of the water onto the stern when towing it, that reduces drag as only the bow is actually in the water (only on calm days as a following wave would fill the nose).
Lessons learned are opportunities earned.
