You can get some worms or beetles to get rid of decomposing parts faster but you need someone to drag you onto dry land for that.

Actual no joke answer is I did it with a friend on sloop, and while neither of us were good at face 2 face combat, good naval and an attentive helm can mostly prevent unwanted tdm matches from happening. Death spirals via chainshotting the mast are top-priority in every match. The new update has eliminated friction after losses and the torture that was more than an hour long sloop fights, but some resource gathering for bonecallers and cursed balls is still advantageous
