I have this....
as a dog.. he once went sailing...stupid dog jumped in the water...total weight was almost 180 pounds...I couldn't hoist him even with a makeshift canvas thing...he stared crying and swiming away from the boat...
I had to inflate the tender, get it in the water, and towed the dog to a beach..then got him on the
dinghy and he jumped on the boat...we tied him down as he wanted to jump gagain...I lost a lot of time..never again...make sure you study all possibilities...they don't like being hoisted, its not natural for them...and will sactach the boat and behave funny once they feel they are in the air...leave the dog at home...if God wanted them to be on sailboats, they would have masts and sails..
But if you must insist...build a ramp witha board and use the thender as a platform for it, the other end in the bow.
