How do you make modifications to a home you do not own? For example, the houseboats we rent from Paradise Point for ephemerisle do not come with curtains around the bunks. People jury rig rope/sheet curtains with duct tape, but this risks damaging the finish of the paneling on the boats.
One possible solution is to use suction cups, and tying a rope between the suction cups. Here’s a few of varying strength and prices:
Addahook The Heavy Duty Double Locking Suction Hooks (holds about 10 lbs):
Generic Uline Industrial Suction Cup (holds 100 lbs)
4 1/2″ SeaSucker with Aluminum Handle (120 lbs holding capacity)
Check out the SeaSucker website for many more ideas on how suction cups can be used.
