We have a couple of sea kayaks that we might take cruising. The problem is that they are about 17'' long and weigh about 60#s. Does anyone have any experience with sea kayaks on sailboats??? Can you tie them to lifelines??? I have got into mine from a dock but never from a boat especially with waves. We enjoy them a lot but I''m afraid that they might be too much trouble. We are shopping for a boat right now. If you are using sea kayaks please tell me the type/size of boat. We are looking for a 30-35'' boat.
