Just bought YAHOO,25 cat from Modesto Cali. hopping to talk to former owner with upgrades and how they all work.Big Question for now is once that big piece of iron is down can it be locked in so it doesnt move??Or was that a problem with the design?? Nice boat with new home on Vancouver Island.Launched today and had lots of problems getting the mast up rigging confussing etc etc Look forward to putting it all behind me soon.Look forward to this form.TX barniclebob
