In English ‘hove’ is the past tense and past participle of the verb ‘to heave’. It retains those functions when in the compound verb to Heave-to. Thus: ‘Please heave-to’. ‘I have hove-to’. ‘That boat over there is hove-to as well’. ‘We were both hove-to yesterday afternoon’, It ought to be clear enough, but not to some people it ain’t: hence my lengthy examples. Personally I rather fancy ‘I have hoven-to’ for the past tense. Either is permissible, but the older ‘hoven’ pleases me. At all events, please refer to Heave-to.
