Re: getting a Tartan 34C ready for offshore trip
I think closing up the lockers with bulkheads would be ideal. Making sure they have heavy duty latches and hinges that lock would be a fall back position that would probably suffice.
I'm guessing you have have the vent on the fore deck just aft of the hawse pipe that would also be a concern for down flooding. If you seal it and can fabricate a semi permanent plug for the hawse you would probably be ok.
Just keep in mind that these are vulnerable points in the event of a knockdown, and secure them accordingly.
